02-06 00:27PodcrazyIf it says in the View box that white can tenuki, why is it labeled as bad?
02-06 00:24I am still weak, but as the ladder doesn't work, how does this help?
02-01 07:32so theres only 18 people on this site
01-31 05:20S17 before O14 is answered simply with O16. Very good result for Black.
01-30 15:24What the hell is this move doing here? Plz get rid of it!
01-30 03:51すごい手ですね。私も打ってみようかしら
01-12 20:03SampiS19 and S13 are not miai. If black plays S13 white dies.However, professionals have been known to live and create ko in this corner as white with different sequences.
01-09 06:24Perhaps the question you should be asking is in what sense is this possibly good for white?
01-08 08:30Funny variation :D
01-06 16:23I am wondering about this move too
01-05 08:20why is that bad for white?
01-05 07:30i would hane p17, for me its best for black
01-03 07:18Is M15 good for Black?
01-03 06:13Takemiya also played this one
01-02 15:35Yoda Norimoto has recently used this move in one of his games and It worked out okay for him. I don't think it can be called bad.
12-27 15:39is ko really a settled position?
12-27 13:33Depends heavily on what is in the corner closest to this move.
12-19 12:34I think you would kick the p17 stone and make white overconcentrated.
12-18 17:26BrilliantGo Seigen recently commented that this was a bad move by black. However, it has been speculated that this is simply an attempt by Go to raise awareness in the Go community of other opening styles. In fact, Go was the first person ever to play this fuseki as black, and it remains reasonably common amongst professionals.
12-18 17:22BrilliantI have marked a couple of sequences following from a black pass. They are not necessarily joseki, but they are examples of the kind of thing that can go wrong for black if he passes.
12-18 12:37could anyone explain why it's considered bad move?
12-18 07:44What if black ignores this joseki and plays elsewhere?
12-17 20:58I cleaned up. I think it's good to let people know that M11 local move exists, and that L10 response is generally not good (I have seen kyus play it occasionally, often with one of the deleted "followup moves" from here ending in not-a-natural-tenuki).Whole fuseki from single pro games from the 1930s are interesting, but not desirable here.

12-17 05:57a strong taiwanese player at our club says that this result is better for black because later on in the game the aji at s14 can come into play
12-16 00:09sinse33If is good for white, why R17 is not the best move and just a good move ?
12-16 00:03sinse33What is the best move for white after black play [p14]
12-05 15:31Why is it good for white if there is a move labelled as 'mistake' for white?
12-04 05:14anyone knows a continuation here?
12-02 08:07How is the continuation here? Where should W play?
11-22 18:19BrilliantIn what sense is it incorrect? If you read the comments earlier in the sequence, you will see that it is labelled as a way to refute mirror Go. In that sense it is an entirely legitimate sequence.
11-20 04:05Could someone correct or remove this sequence please?
11-17 18:15I am questioning this as being superior to another extension due to the sequence I have entered following it.
11-10 10:24dkillerIn fact the black stone don't negate white wall and there is still some aji starting with R13 if I don't mistake
11-06 00:18This is much better for White than the joseki. White can yet improve by avoiding the P8-Q18 exchange.I hope that helps.
11-04 07:49DarkSyctheProbably this is slightly better for Black than after white pushes once then jumps
11-03 16:14Played when black has supporting stones that can trap/kill white group when it escapes towards middle.
10-30 18:17If R15 is bad, what is a good move for B? If there is no good continuation, why is S17 marked as ideal?
10-22 23:46This black move is described as incorrect in Yilun Yang's 'Tricks in Joseki'
10-19 21:49blargyity blargitiy blarg
10-16 08:22This seems to be the among the most popular moves with professionals in this situation, so I feel it is only fair to call it ideal rather than good.
10-13 04:24leitet in anderes Joseki über, das entsteht, wenn S direkt auf p16 mit p15 anlegt. Daher kann q15 nicht als schwach angesehen werden.
10-06 18:39JoeSekiThis is the right move, black has to protect O15 or he loses all those stones
10-03 07:47чем этот ход плох???
10-02 13:27BrilliantIf something leads to complicated variations, is it necessarily a trick move just by grace of its complicated nature?
09-30 09:09BrilliantI have put some ideal continuations after this move based on games from my professional database, but the database has 017 occur 95 times in total, so none of the variations have a huge body of work to back them up.
09-26 17:07BrilliantThis move does not appear to achieve anything at all.
09-22 15:14BrilliantI don't understand your comment. If white plays k16, black still has sente. Q18 is far and away the most common move here among professionals.
09-20 19:40sinse33This move is the correct answer, but [q18] for white is bad, because black keep sentewhite need to play near [k16]
09-19 15:00The historical proverb is not that "a diagonal move is never bad". Shusaku said that THIS diagonal move will never be bad no matter how far in the future. Another, different, proverb says that the one-space jump is never bad. All these have to be taken with a grain of salt since whether they are good or not depends on the surrounding position.
09-15 16:56BrilliantI am calling this good since, despite being the standard response for punishing this mistake when you first learn it, it is never the response played by strong players. Indeed, it feels almost like a trick move.
09-13 06:41BrilliantWhite is dead ;)
09-11 20:31SampiBlack takes the corner? what??
09-07 10:30omgn00b_kgsI've played as black that way, with K16 and D16 (san rei sen)Is this good?
09-04 13:14BrilliantThis is clearly inferior for white.
09-03 06:48How should you approach this then?
09-01 09:18How can thispossibly be good for white?
09-01 08:48This move is fine when the top side is most important and white needs to invade.
09-01 06:43This move just means that black captures one more stone and finishes in better shape than the normal variation. Since it offers no improvement for these things, it cannot possibly be good.
08-31 18:00Did someone say Aji Keshi?
08-31 12:57My database has a winning percentage for this move when it is played by black and a losing percentage when it is played by white, out of 80 and 40 games respectively. Both times the results are close to 50%, though, which makes me feel that it is at least a good move.
08-29 14:45SampiWhy is this a bad move if it has been played professionally?
08-27 17:48This move has a losing record in my database, but (obviously) has pro examples. Changed to good pending a source on 'bad'.
08-27 17:33*Tengen* has been played professionally and I think can be happily considered a shinfuseki move. However, some of the lines marked "ideal" should be "bad" and the "normal" (tried by professionals) "center approach" is missing (I will add it now).My cause for concern is that I've seen (weaker) players trying ""openings" on KGS I believe they have "got" from here.
08-27 17:23Unless some high level examples or commentary are cited explaining this, I think we should change this line to "bad" or remove it (meaning no disrespect; it appears to be unplayed and defies normal opening theory).
08-24 18:37I am going to be brutally honest and speculate that actually, I am not convinced this sequence is Joseki at all.
08-21 15:02Phillip Priddyor you can try goshrine to compete against other go players
08-21 12:31BrilliantThis (or a number of other sequences) are playable for white as a continuation, but are not really joseki any more.
08-20 13:58BrilliantWhilst not common, this move is played regularly in professional games, even when neither player has any supporting stones.
08-19 12:11BrilliantIn what sense is this a good move?
08-14 09:52DarkSyctheWhy is this a mistake?
08-14 01:35Best response?
08-14 01:35From a professional game. What are the ideas behind this move?
08-13 13:13BrilliantAccording to my GoGoD disc, there is no instance in which any professional has approached the 5-5 this way. This position only occurs when p15 is played as a ladder breaker.
08-12 14:50SampiI've marked this move as ideal because... why wouldnt it be? It's been played professionally.
08-09 07:44Not, nessecarily bad. In KJD, black gives secure 4th line terretory.
08-05 18:00BrilliantAt the end of all the sequences that have been listed here, I can't help but feel that o14 looks misplaced - in some situations the position would actually make more sense were it not there at all.
08-05 17:53BrilliantIf you are still looking for professional game joseki, Eidogo has a decent selection of professional games and a corner pattern search facility.
08-05 17:51BrilliantThis the (a?) normal result when black plays 3 from a 4-4 point, but now it seems too good for him since w can't invade effectivley any more.
08-05 17:42I have not been able to find a good continuation for white after this move by black.
08-05 13:07DarkSyctheSan-san is not a trick move. I have no idea who would ever label it as such.
08-01 09:12Can someone add more information about this ?
07-25 15:06SampiThis makes no sense...
07-25 12:08xiumaI think it is not good, baxauce Black plays San San und White leaves weakness, so hi should play one more, but there is no move which is a good continuatio.
07-24 12:35I am quite new to Go, but I do not understand why this is a mistake. It would seem to expand white's ability to gain territory on the right and is not easy to cute in isolation.
07-21 05:018p played played this against me in a 4 stone handicap game.
07-14 17:48adumseems to be a new pattern from Lee Sedol: http://gogameguru.com/commentary-xie-he-lee-sedol-8th-chunlan-cup/
07-14 14:57DarkSyctheChanged to mistake because of 1.
07-05 13:10hola
06-29 18:14DarkSyctheWhy is this a mistake and R10 not?
06-28 19:38sinse33This sequence is correct ?S19 and S13 seems miai
06-28 15:09DarkSyctheChanged to good because all of the sequences after White 2 are at least slightly good for White
06-26 19:42This is the way out.
06-26 06:25yo
06-25 19:03Josekipedia.com is correct! Ding,ding, ding!
06-25 19:01This is good for white.Black seems low on the 3rd line and 2nd line.
06-24 10:59DarkSycthechanged to mistake because the only sequence provided is good for Black.
06-21 18:57DarkSyctheThis has been played by professionals so I don't know if you can really call this a mistake.
06-20 16:59Pariah.Priest@DarkSycthe - I get where you're coming from, but I'm looking for specific situations. Not just opening moves. Perhaps even some old game records of Professional Go Players.
06-20 11:52DarkSyctheThis move is very slow, so maybe a simple jump such as R14 could be a good response.
06-18 17:45DarkSyctheCan this be playable for Black? Black has less points than White!
06-16 18:21DarkSycthePariah Priest - this site :)
06-16 16:45Pariah.PriestDoes anybody have a good site where I can get some joseki for free?
06-10 09:55Das fernbleiben von Schwarz nach Q3 finde ich fraglich. Schwarz profitiert meiner Meinung nach nicht ausreichend von dem zusätzlichen Zug unten rechts, um den Cut O4 auszugleichen. Zudem konnte Weiß auch noch mit C11 die Ausdehnung verhindern.
06-07 15:25this was a mistake, move shouldn't be deleted
06-05 09:30According to my database this isn't a mistake, it's the most common continuation.
05-31 17:09i dont know, if these are really "ideal moves", but maybe these are ideal for this kind of strategy. the corners were not clear w's territory, but open for attac. black gains influence over the center. but personally i wouldnt play this as black, too ;-)
05-30 18:29sinse33Good if black have a stone on d16 ?
05-26 10:06DarkSyctheNot sure if this is joseki or not but I think this works for Black.
05-25 16:23DarkSycthep17, sorry
05-21 17:55after a sequence like this, W would like to move T16 to S17
05-20 14:14まいどー(^笑^)/白後手になるのでノビが良い。
05-20 14:13まいどー(^笑^)/白味悪そうな気がします(ー。ー;)
05-20 14:10まいどー(^笑^)/一着ある方が手厚い。
05-20 14:09まいどー(^笑^)/シチョウで取らなくてもいいかも(=´▽`)ゞ
05-20 14:05まいどー(^笑^)/黒は隅を生かして外勢を得ます。
05-20 14:01まいどー(^笑^)/一段落。右辺展開の足がかりを用意してまずまず。
05-20 14:00まいどー(^笑^)/ハネると右辺展開か隅の生きが見合い
05-20 13:51まいどー(^笑^)/よくある展開です。
05-20 11:43DarkSyctheI think the idea is that if White doesn't respond Black can start attacking the stones. Otherwise, White can easily make eyes by capturing that stone.
05-04 23:10VoseI have seen this in pro games so I would say it is Ideal?
05-04 23:10I have seen this in pro games so I would say it is Ideal?
05-03 04:40jokepHow is the continuation here? Is this move really correct?
05-02 01:18jokepHow is the continuation here?
05-01 11:21good for white ????????
04-30 13:42erinnert das nicht an eine variation eines 3-3 joseki nur umgedreht und mit p17 und o14 ?
04-30 02:12White played approach move and he got sente. It's ok.
04-26 08:58Shijimawhy is it all blue? stupid!!!
04-24 16:32tailswQ19 bS19 wT19 bO19.
04-24 06:10VoseHow can W answer this and get benefit?
04-24 06:10How can W answer this and get benefit?
04-23 15:57DarkSyctheBlack should cut at 1 anyway before trying the trick play on the side here.
04-23 15:57DarkSyctheThis doesn't allow the ladder to work., so I don't see how it is a trick play.
04-23 15:56DarkSyctheThis should be the branch for the trick play.
04-21 19:32I don't have a source, but I believe this clamp is considered too early unless W has a stone at R12 or so. I was told by a 7dan that W should extend on the top first.
04-20 00:04AmonMISTAKE "for black, against the approach he can adopt solid measures such as 3, 6, and 11," [= The Number > 11
04-19 15:15DarkSyctheso Black must have this ladder, right?
04-05 22:08pfff, qui a mis des sequences idiotes comme ça...comment ça peut être joseki ça!
04-05 22:04^^ c'est pas du tout un mauvais coup !! ne dites pas ce que vous ne savez pas (voir cours de guo juan, ou parties de lee changh ho ;)
04-04 20:25sinse33seems a better respopnse for white
04-03 01:49VoseI think that it is great to have fuseki as part of this dictionary. It is good to have and talk about all broad elements of opening patterns. This could be the best place to do that.
04-03 01:49I think that it is great to have fuseki as part of this dictionary. It is good to have and talk about all broad elements of opening patterns. This could be the best place to do that.
04-03 01:29VoseIt seems to me that white gets too much from this? What do you think? Also black seems to not be settled yet so by the time black settles white has gotten the profit. Black may tenuki but I am not sure. (Do I post this here or in the view section?)

03-31 07:04mafutrctYSY 8p: bad move, gives white chances
03-25 21:56by me on now
03-22 17:49sinse33seems a bad move because white can play P19
03-17 07:04what if black q17 stead o16? less complicated it seems? then w o16, b r14
03-13 03:46GelyaYeah, an interesting move. My opponent tried it on me. I think black must have the ladder to play this way.
03-11 23:58Is this good for White? Later on White can destroy the corner territory easily.
03-09 13:15After White extends to S17, Black is in trouble. If Black extends to s16, White can cut at P16. If Black connects at P16, White can connect with the single stone at R14.
03-08 22:37why is it a mistake?
03-06 14:45why are black's moves are ideal move?after this variation,w got 4 cornors and b got.... nothing solid
03-05 06:23Including the option of pincering i.e. one should pincer an approach to a 4-4 stone 5% of the time or less?
03-03 23:31sinse33What is the good answer about this move ?
03-03 14:44Seems a lot to give away for third line base making. R13 and R10 not better a line higher?
02-27 06:25takmakприемлемый ход в этой позиции?
02-27 06:24takmakкак чёрным отвечать на этот ход?
02-27 05:21互角
02-24 09:33adumL17 is too close to white's wall
02-24 04:26Isn't L17 instead of K17 ?
02-23 12:32blue88No source, no tags, no description for the path. So I changed this move to question type for now.
02-22 17:25Now what?
02-22 17:18now what?
02-18 09:28Василийя играл так, за черных играть трудно но и выгода есть, хотя играть надо хорошо...
02-18 08:09blue88The Ko still looks like a flower ko for Black and White can't avoid it without becoming a shapeless dumpling?
02-18 08:08adumi have referenced a source calling this joseki. if you want to change it, please provide a source.
02-13 04:38blue88Looks pretty good for Black as well.
02-13 04:37blue88Maybe this is a nice Choice for Black? So far I couldn't find a good way for White, but I didn't really go through the cross-cut variations. ;)
02-13 04:36blue88This looks too good for Black imho.
02-13 04:21blue88It's difficult to find study material on this Fuseki. Looking for responses to White [d16] I only found this sequence played by Kanno Kiyonori 5p vs. Shirae Haruhiko, 5p in an Oteai.
02-12 04:52blue88In my game i played this Hane directly, but it's a bad choice because Black can fix his defects now.
02-12 04:40blue88What happens if Black extends his side?
02-12 04:38blue88After the cut I found two possible respones r17 and o16.
02-11 23:55blue88Compare to Ryu Shikun vs. Cho Chikun. 58th Honinbo League 2002-11-25.
02-10 15:25Is this really a reasonable opening move, with no other stones on the board?
02-07 06:40blue88To me it seems like pushing at [q16] first was better, because now Black has the choice of erasing the outside aji by playing [q16] himself.
02-06 12:09look at go seigen game versus kitani minoru, kitani played like this one
02-06 04:21blue88Compare to Gu Lingyi 5p vs Zhang Wei 6p: 22nd Chinese CCTV Cup, round 4: 2010-04-09.
02-06 04:20blue88Compare to Qiu Jun vs. Huang Yizhong: 12th NEC Cup semifinal 2006-11-04.
02-04 19:10Isn't white very weak now?
02-04 19:08Why is this trick play? Black does not have a very good position
02-04 03:29breakfastWeird move. Never saw it before
02-04 03:28breakfastIt's an old joseki. The result is better for B. No ladder-breakers for White
02-03 13:36blue88This move starts a fight. Many ways to continue are possible.
01-29 13:01jokepWhat is the continuation here? I doubt that W can tenuki
01-27 10:20Василийхм... белые в плюсе...могут играть в другом месте...
01-27 08:58bumping your head into w stone will help w's shape more than b's.I see q17, p15, o15,p14, o16 as a likely continuation.
01-26 12:37blue88Used by Vanq (KGS 9d). Is it a trickplay?
01-26 12:08blue88Shouldn't Black make shape like this?
01-25 14:57This looks solid. Why not here?
01-25 09:24Double hane is ko, but not a cheap ko for b.
01-25 08:15blue88Is White's corner still unconditionally alive locally? What can Black do?
01-24 15:09blue88Looks to me like Black can choose now? Let White make a position on the outside (Black p18) fight a ko for the corner (r14).
01-24 15:08blue88What if Black cuts here?
01-23 17:28my guess would be to attach at either M16 or Q12.
01-23 14:27blue88Changed to question type due to missing source. Added another variation with source.
01-23 14:22blue88You are right. However, referring to "Making Good Shape" there is a new variation, so this move can be played again.
01-20 13:52How can a sequence of "good" and "ideal" white moves lead to a result that is good for black?
01-19 06:07Василийпфф...тупая связка
01-18 09:42this should keep b out of the center, while giving b lots of territory.
01-18 08:02if b has strength on the top side (enough to hane at o18), then s17 will kill
01-17 13:58Василийа дальше????
01-17 05:45blue88I marked this move 'bad'.Don't do this exchange with a tripod group!
01-17 05:43blue88After s17 White continues with r15.This is somewhat advanced technique. As a result she got free moves on the outside, which can be used later.
01-16 00:44хм, и что теперь делать черным?
01-15 00:46blue88If Black ignores or pincers here, what does White do?
01-15 00:42blue88Looks like o17 is ladder dependant because of this cut?
01-10 15:46I think black has life aji on both sides, that's more valuable than white territorial expectations here.Am I wrong?
01-10 13:16adumwhat does this kill?
01-09 21:16isnt this bad ? where is the source
01-09 05:41blue88If Black was strong around or had no ko threats, wouldn't he just play here?
01-08 12:41Any better options for white here? please?
01-08 12:40...continuation?
01-08 12:39A little superior for black, no?
01-08 12:37Looks a little better for b, no?
01-08 12:36I can't see anything good for white out of the resulting variations here....
01-08 12:35This move seems to lead to nothing good for white... is there any better response? Otherwise, should this really be considered joseki?
01-08 12:35This makes more sense for black, no?
01-08 12:33This also looks awfully small for white...
01-08 12:32This is ok for white? Really? Black gets the corner, and has already placed a stone negating white's wall, AND he has sente?
01-08 12:31slightly better for white in most outcomes, no?
01-08 12:20This seems to lead to an inferior result to the alternative given... should it be labelled as 'good' instead of ideal?
01-08 12:18Yeah, maybe as a continuation or end game sequence... too small otherwise, I would think.
01-08 12:16Does black need to take? Is this really balanced for white? Black got corner, and is free, and some side; white just got side...
01-08 12:07Is this really so much better for white? It looks possibly even for very advanced players, but white's advantage might be a little difficult to wield...
01-08 12:02This feels too good for black...
01-08 12:00Not P17? Or maybe M16?
01-08 12:00Woah... Jump to middle?
01-08 11:59How does one finish the trick, and finish refuting it?!?! Maddening...
01-08 11:58This does look like *black* did awesome, I now understand what the previous comment meant... How should white play here to balance this?
01-08 11:53I can't see how this could not be better for white than N18?
01-06 18:51What should be done here?
12-29 19:16-.- just tenuki
12-28 19:39i've never before seen reference to second line territory as a moyo.
12-28 14:02extending to p18 is a bad move because w could get a bigger moyo with p17
12-26 00:51blue88Maybe like this?
12-23 16:00DarkSyctheThis looks good for Black. Is there any way out of this for White?
12-21 14:21No, this is refutation branch. black didn't fall for anything.
12-21 12:05so black fell for the trick and it's "slightly good for black"?!
12-21 05:30blue88This sequence happened in my game. Did White play correctly and was Black E3 a mistake?
12-20 07:03blue88What happens if Black plays here without preparation?
12-18 05:07breakfastWrong order for White
12-18 05:05breakfastVery unusual move. More common, if the position is one line higher
12-18 05:04breakfastYes, R15 is bad move
12-18 05:03breakfastNarrow extension is more solid, but everything depends on position. On empty board we cannot call K17 bad
12-18 05:01breakfastWho called it bad for White?
12-13 14:36mabaIf these moves were played in the order 1,2,3,4,7,8,5,6 then white would just have played a bad move according to that variation. How is this possible?
12-13 11:25Black initiates taisha and white collapses
12-12 09:49This happened to me in a recent game. Threw me of guard. Thus I managed to screw things up. I might have played better if it happened to me now, but still, would be nice to know what others feel should be the appropriate answer by white.
12-07 05:16blue88When Kageyama said this would lead to an equal result, White had a Hoshi stone in the upper left corner, pushed once more and then played K17. So I guess he was referring to an equal result globally.When he said the result was bad for White he was referring to the position locally. Please push once more and play L17 to see why it is locally bad for White.
12-07 05:10blue88Ok, this is kinda weird: 40 pages after telling the reader how even the result coming from this sequence is, he indeed says that these pushes are bad for White. (p.94)
12-07 02:24This is endgame move
12-06 08:06blue88There are some continuation paths but none is good or ok for White, so I changed this to a question type move until someone adds a continuation that actually works. :)
12-05 02:24blue88I removed this description:"Allowing black to push out on the 4th line (of victory) is bad.Source: Lessons in the fundamentals of go, by Toshiro Kageyama"Because it's wrong: Kageyama says that White's nice framework is compensated by Black walking along the line of victory SO NEITHER SIDE HAS ANYTHING TO COMPLAIN OF THIS WALK. (p. 56)
12-02 12:37This is an old joseki, nowadays considered slightly better for black
11-29 11:54blue8838 Basic Joseki recommends this move. However, that must be a mistake in the book (or an old variation maybe), because every pro whom I heard to speak of this position (must have been at least 3 pros by now) said it's a mistake for the reasons given in the move explanations.
11-29 11:16jokepno, because W would not play R19, but T18.
11-28 12:20blue88I changed this to a question type because it has no source and the result is the same as in the Joseki from 38 Basic Joseki I added, except for the fact that White has cut already (but should probably save the cut for later).
11-27 18:30DarkSyctheI think this move is rather bad because it gives black a nice wall and sente.
11-23 10:08blue88I removed the description "forced" as this move is by no means forced. Instead White should Hane.
11-20 07:47if the ladder is in w favor, and b squeezes and extends, how unfavorable should it be considered?
11-20 07:40given that b has played an extra stone, if he has the advantage, it is slight.
11-20 03:17blue88This move is possible (38 Basic Joseki p.197) but no continuation has been added yet.
11-19 18:58LindseyKSlightly better for b, no?
11-19 12:13not joseki, this just shows the ladder. w r17 required ladder. b o18 required ladder.
11-19 09:17Couple things to consider in b's favor.Having p18 makes r18 more effective.As far as sides are concerned, b is on the 5th line, w on the 3rd.
11-19 09:06you might be right if you had to have an eye at p15. but extending down the side (or something like s15 or m14) is going to be worth more than the 2 points o16 makes.
11-19 08:54kill is optimistic. i'd start the attack on eye space or shape at o18/o16, or surround at n15 maybe
11-19 08:47this makes n17 an aim for b
11-19 05:22LindseyKWhat? This is Joseki? If the ladder works, this is terrible for white. If the ladder fails, this is bad for black.
11-19 05:18LindseyKWhat a shocking Joseki. It works, I guess, but every move after a certain point caught me by surprised. Isn't this slightly better for white? Seems like he got the better part of the corner, and jumped out first. I would think black also needs an equivalent jump to truly balance, making this sente for w, and this seemingly much better for w.
11-19 05:16LindseyKSo this is slightly better for black? Otherwise, the parent a couple back at Q16 shouldn't be labelled bad, no?
11-19 05:15LindseyKShouldn't this actually be a little better than N16? It's more balanced, and protects against potential future weaknesses, while giving slightly better influence as far as I can tell... Someone higher ranked than me care to elucidate?
11-19 05:14LindseyKYes, very much. White and black both can either reach into the corner or reach out to leave, so they're both in Miai for life.
11-19 05:13LindseyKCould someone talk over the differences between 1 and 2?
11-19 05:12LindseyKHow does black finish off this kill?
11-19 05:11LindseyKIt was said that M17 and S18 are Miai for life--can we see that?
11-19 05:07LindseyKthe problem with this move is that S is a relatively small point compared to the massive waste that this wall becomes when black counters somewhere around L16, for instance. It's a decent follow up sometime around mid game, I think, but first focus on expanding from the wall and salvaging the situation.
11-19 05:00Why is this listed as bad? This seems clearly superior to the move listed as "good", as black is required to respond at 1, giving white better shape when he does kill at 2. Granted, it's terrible to begin with, but this is better than killing, and then being put in atari, letting black have all this while wrecking your shape *in sente*.
11-18 13:26Not a big fan of this result. I wonder if cutting at r17 without the r15/s16 exchange might not be better.
11-18 12:15blue88Happened in my game, when I needed to make a base as White in enemy influence. A simple Ikken-Tobi looked too attackable to me so I played Tsuke at the pincer stone. What do you think about it?
11-18 12:07blue88Happened in my game. Looks pretty bad for Black doesn't it? I think Tsuke-Osae is not Joseki when White has o16 sitting ready on the fourth line already.
11-15 12:14blue88White has to be careful with r17 because there is no ideal variation (or not yet added?) that leads to a satisfying result for White.
11-14 05:34white is alive in the corner and has sente
11-11 23:51blue88Kogo's suggests this move and I've seen it before. Added as 'good' and not ideal because I know neither source nor follow up.
11-10 14:22this requires a favorable ladder
11-10 12:38blue88Doesn't this create a serious weakness at S15?
11-09 14:13blue88I changed this type from Trick Play to Ideal, because if the ladder works, it is a very good move and not a trickplay!
11-09 13:29blue88There is no positive continuation, so I changed this to a question type.
11-08 17:24i have a move that i always do and start this same way and then next white move wood be r17how is that?
11-04 17:06blue88Kogo's says White can still live in the corner with [r17], but how could she?
11-03 09:19i would suggest r13. If s16/17 get cut off, then the s17 r17 exchange is bad for w.
10-31 00:54I see black P17 played pretty often here. It might be useful for someone who knows more than I to work out some variations around that...
10-26 12:53blue88I'm not sure if White needs some reinforcement to play this move, but basically it exists.

10-24 15:07takmakкак правильно ответить на этот ход Б?
10-22 09:56blue88Since the continuation is not complete and there is no source, I changed this to question type.
10-21 09:40What is black's best response to this move?
10-20 12:31blue88Black has to defend but the book doesn't say how. I think this is fine.

10-12 10:50blue88s16 doesn't work I added the punishment given in Graded Go Problems for Beginners Vol. 4.
10-12 03:49blue88Does this move need the ladder that follows Black q18?
10-12 03:46blue88Looks like White needs the ladder to punish this move? What does she do if she doesn't have the ladder?

10-11 13:59blue88Many difficult variations here.
10-11 12:24blue88Why would Black play here? Looks too small?
10-11 08:48breakfastTennuki is best for White, because his corner stone cannot be killed
10-11 08:44breakfastFujisawa Shuko played it first in Kisei titlematch (in Chinese fuseki, against Cho Chikun)
10-11 08:43breakfastIt looks good for White
10-11 08:43breakfastVery rare move for Black. I heard the opinion that it's wrong
10-11 08:42breakfastReally great result for Black!
10-11 08:40breakfastI heard the opinion that it's better for White. Nice wall and sente hane at T16
10-11 08:35breakfastShape is not good, but B's corner is too small.I feel, White is better here
10-07 13:08blue88More detail about this (why J16 without another push first is bad and possible sequences after m14) in Jennies KGS+ Lecture at 02.10.2010 from Minute 59 onwards.
10-02 16:07DarkScytheI have changed this position to a bad move
09-30 15:00blue88Is this just the punishment if White doesn't have the ladder? Or is it really Joseki with Black continuing at Q19?
09-30 14:13blue88It's a trade. Cornel wasn't sure how to evaluate it.
09-29 09:53blue88Sequence played in the 11th Chinese City League. I added it as question path, since no other variations are here yet.
09-28 14:55SampiThis move is not good, as Black can get pressured at P16.
09-22 18:17DarkScytheThis is not necessarily a good move (possible timing issues) but the idea is to make the tiger mouth shape over-concentrated. I will agree this move seems somewhat odd, maybe premature.
09-22 18:15DarkScytheSee the 2-2 point move. Apparently this is inferior for white, although I think it looks ok (though not especially good either)
09-21 11:34blue88I deleted the label 'slightly favourable for black' as Jiang Mingjiu, 7p said about this position that it is hard to say if it's good for Black or good for White. 'It's just a joseki.'
09-20 14:05blue88Compare to 2010 special Meijin tournament: Lee Changho 9p vs Gu Li 9p.
09-20 14:05blue88Looks like Black can still get a ko.

09-19 13:46DarkScytheThe 2-5 point is usually only played against a hoshi stone with an extension.
09-18 09:50DarkScytheSeriously? Slightly better for White? White has no eyes, a floating group with terrible shape, Black has sente, and Black has the corner. Am I missing something or does Black seem to have a huge advantage here?
09-18 09:46DarkScytheand how does black continue?
09-18 09:43DarkScytheWhite needs another move to stop B p16
09-17 18:13adumi think you should add the variations. they look valid to me too. of course, i'm not a pro either :)

09-11 14:38время от времени встречаю этот ход. почему он плохой и как за него наказывать?:*
09-10 13:01totally wrong, it seem this move exist only with a komoku
09-10 09:29blue88Deleted. Please start Joseki in upper right corner and stop adding whole games...
09-09 11:30blue88"Ladder dependent for W. After the attach - hane underneath - crosscut, is there a way for W to play if the ladder is good for B?"This Question was asked in the move description: No there is not, that's why White should not play the second line Hane if the ladder doesn't work.
09-08 13:31gfootWhy does white play here? After black's response, white's M17 stone is very weak.
09-08 13:20For handicap games white passes until all stones are set up.
09-07 15:01adumit's okay to add some fuseki, but this is not the place to input whole games. please go to the Games section for that.

09-06 11:20White has sente and a few points in the corner, but Black's wall is like a block of concrete, controlling a large part of the board.This result is regarded as good for Black locally, but is often White's best choice, nonetheless.
09-03 21:30I have added lines 1 and 2. The situation seems iffy for black.
09-03 03:14Like this black is able to "hane at the head of two stones" which gives him the lead in this "race". Just compare with the joseki. In Joseki black is pressed down, here white is pressed down. Difference is really huge.
08-31 08:23blue88This exchange was played in the 35th Gosei final rd.5 between Sakai Hideyuji, 7p and Cho U, 9p.
08-31 08:02blue88This is the continuation, that followed in 35th Gosei final rd.5
08-30 15:58it's a settled complicated position with a running battle? aren't these tags practically mutually exclusive?
08-30 15:19DarkScytheI think White can just extend along the side (for example Q10). That way Black won't want to play an enclosure (too overconcentrated) but White can still invade.
08-30 13:09blue88I removed the trickplay label because of Alexandre Dinerchtein's (3p) comment on the position:'We cannot call it trickplay, better to say: new joseki.'
08-30 11:14This was played by Cho U against Sakai Hideyuki in 1020 Gosie title. IT was the final game and Cho lost it.

08-21 19:02DarkScythethis isn't really joseki. This is more like fuseki.
08-21 19:02DarkScytheI know this is a bad move because it's over-concentrated (see 3-3 enclosures) but there are times when I have played this when I was strong on both sides and around the central area. Perhaps it should be labeled a good move like the R16 move (which is also highly inefficient) since it can be useful in certain situations
08-18 16:56DarkScytheIf white has a moyo along the top I think this can be playable. Note it's white's turn right now too
08-18 14:56DarkScytheperhaps the best counter is to just tenuki. This works because black has no good follow-up here
08-15 08:03DarkScytheAnyone want to show continuations why this is so bad?
08-15 07:51DarkScytheJust because this isn't a conventional move doesn't mean it's bad. Just like tengen, it hasn't been explored much and therefore you can't really say that this is objectively a bad move. In my opinion, this should either be labeled as good or otherwise completely removed because of the lack of known variations and continuations.
08-13 22:41How white must play in this position?
08-11 21:57This is Chinese Fuseki, not Joseki. I feel like this doesn't belong in this database. All continuations from here on are even less relevant as far as I can tell, but I'll leave that to someone else to delete if desired.
08-11 21:55I deleted this entire line because there was no citation. Also, whole board positions aren't really joseki.
08-11 21:53Anon: You are indeed correct. Though R16 also seems inefficient. Even if you enclosed the corner, black has his stone hindering your expansion along the right side. Perhaps the star point is the best in this case.
08-11 13:43blue88Out of all possible plays in the corner, I think with Q17 you chose the worst. Now Black can approach at Q15 and exert power from his Q10 stone as he planned to do.
08-10 15:27DarkScytheonly played when there are stones in the vicinity around r10. Otherwise it would be much too cramped
08-03 18:26結局小目打っちゃうんやで
08-03 18:25大斜百変やで
08-03 18:24目外し最高やで
08-02 05:01Even if w lives its tiny, just make sure b gets sente and all is good.
08-01 08:46adumyes, White will play P16 immediately
08-01 03:57NhaneWhite must play S19 no ?I mean, he won't seriously tenuki here ?
07-31 16:18DarkScytheI have seen this played before (with Chinese fuseki) and the result doesn't seem that bad to me. Anybody want to explain why this favors white?
07-31 16:17DarkScytheThis isn't necessarily a bad move. It can be played when there is a Chinese fuseki going on. If black replies with 1 (P17) then white plays r15 and happily takes the side (It's good as far as invasions go)
07-31 10:08DarkScytheI think this move should be marked as a mistake. If you compare the end result with the other variation where White plays the correct move of q13, here the q14 stone is too close whereas a stone at q13 would be a bit better placed.
07-25 14:11blue88A KGS 4d showed me this sequence, in a situation where Sente was important...
07-25 08:23njpadinhaI'm confused. Why isn't there a joseki continuation listed for black at this point?
07-25 03:24s17 then?this is stupid joseki!
07-25 03:05what if w play n16?????
07-25 03:01then?

07-05 10:23blackmoaAfter 3-3 Black looks kind of overconcentrated

06-26 04:39Hi, Isn't too good for black ? I think White must extend to Q10 to end this joseki.Black take the corner, the sente and probably a good position to take the North side with K16 or K17.

06-07 14:57thucomThe only advantage I can see to this spot is that it should force a response from black. Since black played the center position in the first place, it should be a valued position to black.
06-07 14:39thucomHmm, no second move. I'm guessing that white would play like they were black next and the effect would be not felt until later in the game. But in the interest in making things interesting, how would white go about neutralizing this position?
06-04 08:03If white does not have a stone on the third line, where should black push?

05-15 16:07tailsDone. Please see [path:pdttpf].
05-15 14:47tailsI'll delete this node, and move all the children into Q14.
05-12 15:58tailsHmm... Strictly speaking, this move should be at R12, like the first move is at Q16 and not at Q4, according to the guideline of this site. Should I flip the positions (this one and all the continuations)?
05-11 07:15MarkingDepends on the postion, if black wants a fight, then P17(taisha) is definetly better.
05-10 07:27What is "san-san break move"?
05-03 10:43..
04-25 07:29actually its really simple, when you for example just play on the 3-3 point and than let black run along on the second line.White gains lots of influence and black just gets very little territory, which is worth not really more than sero.
04-25 05:10To a 15k this seems like really dificult move to counter with white
04-22 16:54This leads to a big exchange: the corner for strenght. But locally looks better for white (the corner is big).Remember, however, that this turns out as a result of black's choice upon blocking at p15. In other words, if black played this way is because he wanted to stress the outside and give up the corner.
04-22 16:51Similar to another well-known variation, but not white's position is somewhat better. In any case, black's satisfied and locally the result favours him.
04-22 16:501 or 2?
04-22 16:49This leads to a big exchange: the corner for strenght. But locally looks better for white.
04-18 17:08tailsI've changed the label from "Good for white" to "Good for black". You can also do that.
04-18 16:30Erreur de traduction ..... pas "Bon pour blanc" mais "Mauvais pour blanc"
04-18 03:45tailsThis move violates the symmetry guideline, and has no continuation.
04-15 14:00tailsPlease see [path:pdqdqcpc] instead.
04-13 11:59tailsI think wO10 is somewhat slack, and Black has many good extension moves along the edge.
04-13 11:03adumthis position is joseki, so it's equal.
04-12 12:28I added this variation to show why black shouldn't play S18. I'm not sure about the continuation but it seems OK.
04-07 15:04Deutch???
04-07 10:06for one, S16 should get you back to [path:pdqfqhqcqdpcocrdrercqeodncrfoesend]O17 and S14 look interesting
04-07 10:03for one, S16 should get you back to http://www.josekipedia.com/#path:pdqfqhqcqdpcocrdrercqeodncrfoesendO17 and S14 look interesting
04-05 10:55Does anyone know the proper white refutation of this move? The cut at P16 no longer succeeds at killing the R16 group, as it would have if black had played S16
04-04 00:13While its true that black can create a wall and gain center influence, you must remember that white has a living group in the corner while black does not. This means that if timed correctly, white could attack black's eyeless wall and gain a lot of territory while black is busy running away.
03-31 06:12This is a trick move, I think - The 2-2 stone is vulnerable, but black's idea is to sacrifice it and gain a strong wall on the outside while holding white down to a tiny corner.
03-31 02:57Black might think that this move is clever and that white is pincered, but this is not the case. Black's S18 stone is no vulnerable and white can happily take the corner insuring life. This leaves black's Q16 stone extremely vulnerable to attack and white can exploit it easily. Playing on the S18 line should be something you do only after playing at least one corner, but even then its not a move you want to make unless you are extremely confident in your ability.
03-30 17:37tailsThat's interesting. Can you show some continuation?
03-30 16:09Jonas JermannDieser Zug führt zumindest zu einem gleichwertigen Resultat oder sogar zu einem guten Resultat für Schwarz. Ich würde in dementsprechend nicht als "beste Widerlegung" bezeichnen...
03-28 20:352008-01-29 zhang li vs zhang weiwei plays the kick in the opening and has no stones nearby. Many other pro games that played this move also...... It settles the group quickly. The label "bad move" itself could be incorrect in regards to go. This is really over simplifing the game a bit.
03-26 02:10UzmestIt is bad if black does not have a stone or more around k16, pro say so, every high dan will tell you that too
03-24 07:14If this is a bad move then why does everyone on tygem use it? A lot of the joseki books out of japan are just trash. I wonder about this one also??
03-24 05:57very succesful with low digit kyu in kgs.S16 is both the intuitive and loosing move.
03-24 03:09this seems to put white in a bad place
03-23 04:14This is joseki !
03-21 18:26surely, black will cut and white will have hard time defending his two stones. Hane seems risky.
03-20 22:37I agree with the other adum and Marking here, the 'kick' here is generally played when there is a stone at the q10/r10 area. White from here does not have 100% life, but is very close to it. (Which is why the stone at around R10 is needed)
03-17 19:40How does White continue in this position? White needs to take care of both of her groups.
03-16 13:56this looks like a sequence from a handicap game. i think w has gained a little. the b stone on the right isn't nearly the worry for w as the w stone on top for b.
03-15 13:43tailsLet's add continuations to [path:qdttod] instead of here, if any.
03-13 10:40tailsI think that this position and [path:peqcoc] should be merged. And, for the other position is better developed than this one, I think the continuations of this one should be moved there.Ryo33, will you add your positions again there?
03-12 12:14s16 ist manchmal möglich
03-10 23:15tailsAnd, to follow the symmetry guideline, this move should be at L10 rather than K9.
03-10 23:12tailsThis cannot be a joseki. I'd vote for deletion.
03-09 21:09gnosI looked this up on Kogo's. I'm calling this joseki for the time being.
03-09 21:02gnosI still see no answer to my question here. The problem I see is that it looks to me like white gets an inferior position at this point. If s16 cramps white's style, what is the point of the avalanche joseki? As a 6 kyu player, I can never get to it as white because my opponents will all S16. Is that joseki? If so, what is the follow up?
03-04 04:04mafutrctJoseki = common sequence, it does not have to be a kakari.
03-04 04:00mafutrctOh it's quite common :) Just an exchange
03-04 04:00mafutrctAfaik, black is never strong around Q10 because then Q16 would be a mistake in direction.
03-04 03:57mafutrctImagine black not playing the hane. That results in two things:1. White is a bit less strong (preverable in midgame)2. White can play S15 to get big yose. Black S15 prevents exactly that.
03-04 03:56mafutrctbirdwm: afaik, yes, it's a one way street after Q16.LindseyK: Afaik, every variation that contains a white atari at R17 is called avalanche.
03-04 03:54mafutrctThis should be fine for both players.
03-04 03:53mafutrctThere are good responses, it just was not added yet.
03-04 03:50mafutrctAfter S15, black S14 becomes gote, and white can tenuki. Without S15, black S14 hurts a lot more.
03-04 03:49mafutrctNo, as white can prevent a very big yose at b S17 and the black shape still has holes. Also, white got very strong, moves like b R9 are not much of a threat anymore.
03-04 03:48mafutrctIt's good shape. Other moves here usually result in worse shape and/or do not satisfy the initialjoseki idea (building influence...).
03-04 03:46mafutrct"Doesn't white need an equivalent jump to balance this out for an end to the Joseki?"- no, as S18 and M17 are miai for life, so this extending would be only yose, and not particulary big.
02-26 18:06tailsThis move must be a pass, and all the continuations are shown under [path:qepc] (opposite color, flipped position). Sorry but I'll delete this node.
02-26 17:54tailsDone. Please let me know if anything went wrong.
02-26 15:52tailsI'll transfer this move from D4 to Pass later.
02-26 14:51LindseyKWhat an interesting, bizarre sequence.
02-26 14:50LindseyKThere are many variations, how can we know which is the avalanche joseki from here? Could someone indicate that?
02-26 14:50LindseyKPerhaps there are special cases where that is true, but allowing a forcing move like that at any other time would be too damaging to be settled as Joseki.
02-26 14:47LindseyKendgame sequence? ....
02-26 14:47LindseyKThat would just mean there were other variants than the one shown that are not yet present.
02-26 14:46LindseyKHow is this a masacre? White doesn't have some awesome wall on the outside or anything... and black has a solid corner, that, if left like this, can still extend from the fourth line.
02-26 14:43LindseyKHold on, the three space jump is considered "ideal", but there is no good response to it being invaded? um, hello?
02-26 14:42LindseyKHow did that play at S15 help?
02-26 14:41LindseyKIsn't this too good for b?
02-26 14:39LindseyKThis is really ideal? This moves seems really random. I'd love to see an explanation...
02-26 14:33LindseyKThis sequence is in the Ear Reddening Game, but I've read that Shusaku made a mistake, though from what I've read it appears Inseki made one first--his last move should have theoretically been at P14, no? This is how the 8dan played it, though, so....
02-26 14:28LindseyKI'm no expert, but as far as I can tell, this is very necessary. -8K KGS
02-26 14:27LindseyKThis is my speculation on how this would ideally continue... seems fairly obvious, perhaps there's something better to do? As it was left, black was unsettled, so I just thought I'd post why--thus this thread.
02-26 14:19LindseyKThere are problems with this branch... an ideal move disappears part of the way through? This sequence perhaps should not be labelled "ideal"....
02-26 14:15LindseyKThis is really considered Ideal? How is an approach on the 2 line a possibly "ideal" move? Surely something is missing...
02-22 11:39This move is ok
02-21 13:43adumit's unclear to me if [src:21st] thinks this is an ideal move or not.
02-20 07:54mafutrctThis move and all continuations is a 30k level mistake - do we REALLY need to include this??
02-19 08:40in isolation, probably b is better as he has solidified territory. But in a position where a b moyo has just been erased ...
02-18 12:16which side comes out of this in a better position?
02-14 20:26chantrealol how do u even save a game
02-14 20:22this has helped me with my go ranking...
02-14 20:20i don't get it
02-14 08:26tailsDone. Please let me know if anything went wrong.
02-12 13:55adumhard to imagine. i will delete it.
02-12 13:44is this really a move that a strong player might consider?
02-12 12:48Kosumi!
02-12 07:28gnosIsn't this Joseki? I won't relabel this until I find a source. But I believed this to be joseki up until now.
02-11 18:40adumthis move is not a mistake, unlike White's previous move
02-11 18:40adum[jiot] actually says that black has influence here
02-11 16:42birdmwsince there is no alternative line, wouldnt the avalance have been started before?
02-11 01:40gnosIf R15 is a mistake then it should be made clear how this is a refutation. Honestly, aside from their being better plays than R15, I can't see why it's a mistake. The best argument you can make I believe is that it's aji keshi. But then that should be explained in the commentary.
02-10 22:00tailsTo follow the guideline, this move should be at S17 instead of R18. I'll flip the move and all the continuations later.
02-10 15:10yoyomaI think this leads to unconditional life.
02-10 07:26I think you will find b l17 / w k16much harder for b than just starting at b m17 / w n18 / b k16(or k18)
02-09 21:16Konstantin V. PleshakovПочему черные забирают угол? Я ошибаюсь или белые еще могут выжить, сходив в сан-сан?
02-09 15:06mafutrctYea, of course, but sometimes it's still better to play here instead of Q12 or R11 as usual. At least this move was played by pros. I'd still vote to flag this as "bad" with an explanation that it is _sometimes_ good.
02-06 04:17breakfastBlack can win the race, but it makes W too thick outside.So, usually it's bad for B
02-06 04:14breakfastBlack plays here, if there is no way to attack White's group.If it's possible to attack W - it's too slack. In this case (with J17) it's better to answer actively by P18 or empty triangle at Q17
02-06 04:12breakfastThe whole pattern is outdated. You cannot find it in recent pro games.White's wall in gote is not good enough usually
02-06 04:10breakfastBut where can you find modern pro games with this pattern?Last time I saw it played in 70's
02-06 04:08breakfastJust outdated. Cannot call it bad
02-06 04:06breakfastBlack can just give up 2 stones
02-06 03:58breakfast70.88.111.22 is right
02-04 18:03What happens if white pushes through immediately instead of playing 1 or 2?
02-04 10:08problem with q11 is the s16/r17 exchange. Without the exchange, If say B jumps in at r12, W r11 followed later by R17 would allow W to effectively sacrifice r14. But after the exchange, W could not find life on the inside.
02-04 09:16mafutrctI'm not going to say this is a good move, but it can probably be played with a low shimari in the lower right.
02-03 18:00tailsSo, the essence of my question is: Is bT19 really a trick move and wS18 really tricked? If this position is good for white, then the "trick" doesn't hold.
02-03 11:26mafutrctThis situation is utterly insane.
02-02 17:34tailsIsn't this position good for White, especially compared to [path:qcpd]?
02-01 17:41gnosI'm unlabeling this as bad move until someone provides a refutation. A suboptimal move may not be joseki but it cannot be called a "bad move" unless there is a clear refutation of it.
02-01 12:53tailsI have transferred this move from D4 to Pass.
02-01 12:27tailsOk, I have transferred this move from P17 to R15.
01-31 16:25przprobsIf white plays like this, he is just giving black sente.
01-31 16:16przprobsQ13 is a mistake unless black has more stones on the side because it leaves the group open.
01-31 16:15przprobsattaching here is usually thought to be too defensive.
01-31 16:13przprobsattaching at n16 is seen as less favorable except in emergency situations because normally attaching against a weak stone is bad.
01-31 16:10przprobslook at l17 for the continued variation
01-31 15:57przprobsIf white doesn't have the ladder, he is in deep trouble. If the ladder is good for white, the result is still not good.
01-31 15:55przprobsFor modern pros, to protect the cutting point is the only move.
01-31 15:50przprobsBlacks thickness is not that great because of the bad aji with R14.
01-31 15:47przprobsWhite plays like this if the right side is important, like in the Chinese Opening.
01-31 15:42also, the peep at o14 would be the main reason why o16 is considered not as good as o15.
01-31 15:36modern pros believe that o15 is better than o16 because white does not need the eye shape o16 gives, and o15 is more solid.
01-31 15:29White plays this way if he has stones in the top left corner, making a nice extention.
01-30 20:38tailsTo follow the guideline, this move must be at R15.
01-30 20:24tailsBecause Black can be tricked, like [path:pdrbqcrcrdqbpbqeqdocpc].
01-30 19:45Why is this tricky?
01-29 11:55tailsThis move should be a pass instead of playing at D4.
01-29 01:26breakfastYes, it's a joseki. Usually B plays like this, if he wants to fight, when his position is thick
01-29 01:24breakfastThis result is usually good for White. Big aji at R13 later
01-28 19:29hyperpapePlayed by Yamashita Keigo in the second game of the 34th Kisei. No idea if it's joseki or what. White had a low solid position in the upper left, black had a shimari in the lower right.
01-28 18:58hyperpapeYamashita Keigo and Cho U played this way in the first game of the 34th Kisei. I don't know if either of the past two movesare good or joseki. Cho, playing black, won the game by resignation.
01-28 10:44tailsI have changed the type from Good to Ideal based on: [src:shojiten,Hoshi Joseki, p. 84]. The book says that this move is honte.
01-28 09:29tailsI have changed the type from Ideal to Bad based on: [src:shojiten,Hoshi Joseki, p. 201].
01-26 07:55tailsI have changed the type from Bad to Ideal based on [src:shojiten,Hamete, p. 85].

01-24 07:43tailsNice job. I think they are fuseki rather than joseki, and should not be included in a joseki database. If there are sequences starting in the center of the board and we call them joseki, then they should be local in the center, like bK10-wL8-bJ8 ([src:shojiten,Fuseki, p. 236]) and bL10-wTenuki-bJ10 ([src:shojiten,Fuseki, p. 237]), but I think they have not been fully evaluated as joseki.
01-24 07:07tailsI have added a description (in Japanse) and some continuations. Hopefully the Question is settled.
01-23 01:04Andre EngelsThis settles the corner for the time being: There are no big points left to play.
01-23 00:48Andre EngelsBlack's thickness is impressive, but white should still be happy about living comfortably after having played 2 moves less in this corner.
01-22 06:18mafutrctisnt this joseki?
01-22 06:11mafutrcti deleted some variations starting from tengen. they were empty anyway. does not make much sense to have tengen anyway in this database.... (?)
01-22 06:09mafutrctabout the description: this definitely is an "approach" by definition of that word. i think there was a translation mistake, maybe the author meant that this is not an "approach aiming at the corner"
01-22 06:06mafutrctthis move was discussed in detail at http://mafutrct.wordpress.com/2009/06/16/mafu-studies-joseki-15/. I asked various mid to high dan players, so there should be no retarded mistakes. however, it was never verified by a pro or book. should i still add the variations? btw, the final result was that this move is 0.5pt worse than joseki.
01-22 06:03mafutrctbut it leaves a weakness, so you have to consider it carefully. anyway, this is already very deep in the variation, so of course you xan implement different ideas here depending on the board.
01-22 06:02mafutrctyes p14 is also possible.
01-21 23:39adumThis is joseki according to [src:sps,p. 141].
01-21 23:09Andre EngelsLooks bad - white is strengthening the stone she should be looking to attack. I can find one professional game where this is played, but in that case there was a strong black wall as the backup along the 6th line.
01-21 18:02Andre EngelsI think P14 would be a better move.
01-21 03:33tailsHi, 220.255.7.* user. We don't need this move in the database. This move is rude only as an opening move, and just a symmetry as a joseki move.
01-20 13:28mafutrcti don't see a problem with tenuki..
01-20 13:07mafutrct?
01-20 12:36mafutrcti'm not sure about the result. i think it was ko? anyway it is not optimal.
01-20 12:34mafutrcti'm not sure about the order of this move. inseong made a mistake in his documents sadly.
01-20 12:23mafutrctI thought this is a bad move?!
01-20 11:33mafutrctthese statistics are far to small to be considered, i think
01-20 11:23mafutrctBlack is a bit thin
01-20 10:55well if b r15 fails ;)(i think it depends on the ladder?)
01-18 16:49tailsAnd it was me, forgot to login.
01-18 16:47I have deleted all those variations starting from white. (Actually, they all had no continuation, only one white stone for each.) Let's not have them unless there is a good reason.
01-16 21:01adumthis is a mirror of the other 4-5 point. as we only show variations down and to the right of the diagonal, i am deleting this starting point.
01-16 13:54Henry HemmingThis joseki leaves white in gote.
01-16 05:06tailsThe book says this is greatly good for black, so I labeled "Good for black" again.
01-15 23:53Andre EngelsPlayed too rarely to choose among variations.
01-15 23:50Andre EngelsPlayed in the days of Doseki.
01-15 23:43Andre EngelsThe usual move if white has a pincer down the right side; I changed from 'bad' to 'good' because there are cases of professionals playing it with the right side empty (about 20 times in my GoGoD-database, which is about 6% of the cases in which the previous move's position appeared with both sides empty)
01-15 10:26adumi think you mean previous move? i agree. i have changed it to Ideal.
01-15 09:43Andre EngelsNeeds support in the lower right corner; however, normally this is the case when this position is on the board.
01-15 04:18tailsSo, in what situation is this the best move?
01-15 03:00mafutrctI changed it to "good" and added a comment. please check if that is ok.
01-15 02:55mafutrcti'm not sure why this is bad?
01-14 21:54Andre EngelsBlack gets a nice amount of territory, while white has to worry about the cut at P15.
01-14 21:25Andre EngelsThe white stones are light.
01-14 21:20Andre EngelsVarious continuations have been played here, but I cannot find any to choose over the others.
01-14 14:34tailsIt was me, sorry.
01-14 14:32The book explicitly states this is worse for black than the other move. (It is written in Japanese so I can't fully quote it here.) Maybe you can mark this move as "good", despite of the book, by explaining the situation in which this move is the best.
01-14 13:50Andre EngelsIf white captures the stone at N17, she is very solid, but saving it is heavy.
01-14 00:52mafutrctthis leaves better yose for white. i'll mark it as bad.
01-14 00:32mafutrcti think this should be joseki as well. mark as ideal?
01-14 00:30mafutrctafaik both moves are common.
01-13 23:24mafutrcti agree that this move is soft, but since it is the best possible move sometimes i'd regard it as a "good" move - not ideal, but also not bad. i don't know if the source explicitely states this is really "bad".
01-13 23:09Andre Engels'Hane at the head of two' is a proverbially good move.
01-13 15:36tails has a source for his claim -- mafutrct, if you can find a reference that refutes it, let's hear it!
01-13 15:23tailsThis move is too soft when you could choose the other move.
01-13 08:03mafutrcti think this is not a mistake
01-13 07:41mafutrctthis move should be at R16 to be consistent
01-12 11:44if w protects the cut at M17, then b Q18 takes the corner
01-11 21:05gnosIs this position settled? It looks to me as though black can monkey jump and kill the corrner if white doesn't respondOn the other side, black can cut successfully and break out.It seems to me that this cannot be the end of the joseki.
01-11 08:18isdThis move invites black to secure the corner territory and take liberties from the white stone at the same time. In normal circumstances this can only be described as a bad exchange.

01-07 15:37I'd like more detail and commentary about this refutation. Why is it a refutation? Believe it or not, it's not that obvious.
01-07 14:34I added this extension, and added the text "the usual extension from the 3 3 stone". However, someone I played against told me that the large knight's move is more common... I don't know which is the case. Can someone informed please comment on this so we can get it right? I'm not adding the large knight's move because I know absolutely nothing about it. Informed people please speak up.
01-06 13:25looks better than P17 to me
01-06 10:15Yes it is. The point with this move is to invite white to take the corner so that you make "2 moves in a row" against the corner stone. And although it is a unusual move profesional players have played it: http://senseis.xmp.net/?46PointTo me it looks like Q17 is an better answer as Q14 doesnt seem to be threatening to take that stone or shut it in the corner.
01-04 15:34I would assume the question move (8) would be less desirable because the points white gains on the top aren't worth as much as the influence from allowing black to drag out so far.
01-02 10:55MarkingThis is only good if there is a pincering stone around R11. This is because it makes white stronger, and the corner isn't yet secured.(it can still be invaded at 3-3)
12-31 11:29adumi agree -- this probably should be 'Good'. i think this is a good variation if white wants to take away territory and black's influence won't be valuable.
12-31 09:33gnosI understand the labeling here. White has to do something about that corner and invading gives black too much influence. However, Since this technique was used against me with great effect, I would like to know why this is a "mistake" and not just "not joseki". The 3-3 invasion is labeled as joseki, and this doesn't look all that different.
12-28 21:56adumhi, these questions are better suited for the forum. you can choose your language through either your browser settings or your user settings on goproblems.com.
12-28 11:09Is position settled here?
12-28 11:08....? Is this considered Joseki? Is this settled? Is this finished? This looks like black got a massacre...
12-28 09:35gnosMore detail on this refutation please. It looks like if white presses he gets bent four in the corner and black get's a thick position. Please elaborate this position!
12-28 09:31gnosMore detail here please
12-28 09:30gnosI (7k on KGS currently) got tricked by it as black. I believe the presence of nearby stones can strongly affect how good or bad this move is.
12-28 05:59LindseyKAlso, how does one choose which language one wants to view in? I made an edit in Esperanto, and now I can't see English when I switch to "view". :\
12-28 05:52LindseyKI asked this on the forum, but perhaps it's good to do so here as well; how does one go about translating the website, labels, etc.?
12-28 04:34vinhanlook at joseki Kogo for example
12-27 19:22JagarBlack can play here if white already has a stone around k17.
12-27 11:15adumfor this site, we wish to remove symmetrical patterns because otherwise it is hard to find things and a waste of effort. therefore, we always choose down and to the right in a case of symmetry, and so i'm deleting this move.
12-27 05:20MarkingThe 5-5 point is considered joseki, but since it's so far away, it isn't very efficient. (that's also the reason there aren't any specific joseki's for 5-5) However, if you prefer influence over territory, it might fit your style. I myself don't see it as an "ideal" move, but a "good" move, but there are many other opinions.
12-26 15:05This is not joseki, this is invasion
12-26 06:53yes, leading to a black wall in gote for white if he wishes to retain an eye at S14. the shape is virtually useless for white
12-25 05:57vinhanthis is bad move . i think . sometimes it's only use to probes
12-23 21:49adumi don't think this is really joseki
12-23 13:31gnosPlease explain why this is a mistake.
12-23 08:18adumlet's leave the center point (tengen) as the one center opening unless there's a reason not to.
12-23 03:12Isn't the 4-6 point also sometimes played?
12-22 21:07adumthe labeling is a good issue to discuss on the forum. i'm pretty sure the 5-5 is considered joseki, though i don't know any books that cover 5-5.
12-22 19:42gnosAdding the 2 4 approach as "good".
12-22 19:39gnos4463 enclosure. Adding as "Joseki".
12-22 11:44gnosThis sequence looks very good if black has one or more stones around Q10 .
12-22 11:01gnosWhat about tenuki here for white? Since white has two eyes already, isn't that better in alot of cases than just preventing the forcing move at P13?, for example, if black is already strong around Q10?
12-22 10:42gnosAccording to Eidogo, This move was an innovation of Kitani Minoru's, taking sente while taking a slight disadvantage locally. A lot of detail and a lot of detailed commentary needs to be added to the refutation here.
12-21 20:01John KerpanNotice White only has extended three spaces from his three stone wall. If he goes further, a Black building move in the area might risk invasion of a thinner position.
12-21 19:58I think it is important to note that this should only be used when White does not favor one side or the other. If White actually wishes to build a moyo on one side or another, it makes more sense to approach directly from that side. Otherwise, Black has a chance to make the moyo an empty skirt.
12-21 14:44adumfor now, there's no automatic way to do this, but you can put links to positions into the descriptions.
12-21 13:23Any chance we could sequences with different order of moves combine in some manner?
12-21 11:24aduminteresting sequence... does black R16 next?
12-21 09:58adumi think this is only good if black already has a stone around [r11].
12-20 11:10gnosAdum, this move is not labeled so I assume it is not the start of a variation. I do not believe it is the end of a variation either (There should be a way to know this for sure, like marking a move as "unfinished" or something.). I assume you intend to add branches here. I was going to add the branch I found on gobase today, but I'm not sure I understand how this works. I will wait for you to add at least one branch before I do anything here. Will find simpler joseki to add in the meantime.
12-20 08:20gnosIs the 5 5 point actually considered joseki? I've played it and had difficulty getting a good game out of it. I don't see any variations of this yet that are labeled joseki here, but if there are any I'd certainly like to learn them. So that brings up a nice technical question, if there are not any known joseki arising from a certain point on the board, do we label it green or brownish green? I see the logic of making it green, it's just a move after all, has nothing to do with joseki yet until the other player responds locally to it, and we don't want to say that this particular isolated move is "not joseki", as though it were somehow wrong (from the point of view of joseki). But some might contend that if there are no joseki arising from it then it is not joseki and should not be labeled as such. I would vote to keep the green labeling, but it is worth hearing the opinions of other people on this issue.
12-20 01:34dkillerIf black is not captured please present a refutation
12-19 22:32apetrescTo answer your question, it's in the "Edit" tab, second menu in the "Tagging" category.
12-18 16:17adumhmmn
12-10 16:12adumtrue, this is not the avalanche. the large avalanche is [path:qdodocpdpcqencnd]
12-09 14:12adumthanks for your comments about Brugo -- i had missed some things and have updated the comparison page. i don't want to be unfair =) we can discuss more when i have the forum online.
12-03 13:30The comments "... often translated to english as the great Avalanche" is not true, the Great Avalanche is a totally different joseki.
12-03 05:37brugoI see this website is a merge of ideas of other seperated services, which is always nice to see them combined.However your comparison is not really complete in my opinion.- BruGo also supports color codes- Brugo also lists the recently added sequences. - In fact brugo allows to ask questions both by feedback forms, joseki can be added by the users as well, and there even is a forum (the forum is currently down due to server migration though).Of course there are also a lot of criteria missing But it's understandable from a market point of view not to mention those. :). Perfectly understandable.But for the rest, I must admit I like your websites and the ideas behind it. Welcome in the joseki world. :)
11-13 04:20santa chm, when i add a question it keeps the description ("please add a description here and only write something which cannot be expressed using the tags" or something along these lines in hebrew if i chose to save the position >
10-30 02:57Bassyet more testing
10-19 18:19adumI meant in [src:aaj].
10-19 18:18adumNot at all like [path:qdoc].
10-19 18:03adumi like to study [path:qdodpgqcrcpcrekc] sometimes.
