The idea behind
If White does play at
This variant was played by Yoda Norimoto and Cho Chikun in the 1999 Meijin title match. It shows the main problem that White might have in this joseki: In this fight, Black might well be able to build territory on the left side while attacking.
After the game, the aggressive move of
Extending along the upper side with For a thorough analysis of White's threat of pushing at b see 4-4 point low approach tsukenobi, degiri. Playing at Black a next is not a good strategy. If Black finds himself wanting to play here, he should have played here directly, and not have applied the tsuke-nobi first.
This tewari analysis shows why:
But Black can do even worse. Exchanging
The proper way for White to play here and use her aji, is the invasion at
Playing
Giving atari from this side does not help White either.
Gounter:
Is
However on the other side: if White tries to connect to her stones on the right, she dies.
Same result.
So this way is probably better for White. Black sacrifices his two stones but takes back the corner.
Your diagrams are correct, but the conclusion which you draw from them is wrong. Having White live in the corner like this is no problem for Black at all. Sure, Black has lost the corner territory, but his gain in thickness is worth much more. On the other hand, your last diagram is not very good for him. Sure, he has kept the corner, but it is only 7 points in size. White's territory at the top is clearly larger. It might be playable for Black because the white stones on the left side are almost dead, but if I had to choose I would not hesitate a moment that the first diagram is better for Black. Black has more thickness and about as many points, White has less thickness and fewer points. - Andre Engels moved from 4-4 point
''However, it is also possible to play an attachment (tsuke) against the approaching stone, such as the old joseki sequence in this diagram. (Black often chooses to play 9 elsewhere.) There are also various other options, such as a pincer against the white stone from the direction of 8 in this diagram. What is important is to envisage what shapes your stones will have after the sequence has been played, and to evaluate how this shape will work with your surrounding stones. Bill Spight: I don't know why Go books persist in calling this a joseki. It has been known for over a century that Black 9 is inefficient. Black a instead is good. Maybe they think that Black 9 is OK in a handicap game. <shrug> Charles Matthews Indeed, I recently saw Magari 9 dan in a lecture set up this joseki in the four corners in a four-stone game, in a spiral pattern. And then after a short continuation claim that White was leading. So this sequence must shed quite a few points. Crippler?: According to Ishida Yoshio, when playing handicap games with 6 stones or more, making an iron pillar is the good way to play instead of black 9''
I saw this in a korean game, between 11 gup and a 5 gup player.
Charles Ladder? Maybe
Black seems not to have anything here. Sazn: Well ladder or sacrifice stone action
