Pushing battles in joseki 8
  Difficulty: Dan level   Keywords: Joseki

[Diagram]
Diag.: Atari underneath variation

Black 7 from beneath (rather than at a) is given superficial treatment in Ishida - just two diagrams. See Three Four Ikken Kakari Low Small Pincer for those. There is a ladder question, but this joseki occurs in pro games even when the ladder is good for White.

That is, the following development is sometimes seen:


[Diagram]
Diag.: Atari underneath variation

Naturally with a bad ladder White 5 will set up a net instead.


[Diagram]
Diag.: Pushing line

Instead Black 2 is correct shape to hold everything together. Black 5 as shown is now joseki: Ishida gives White at a (Sakata Eio-Fujisawa Hideyuki 1961-03-08) which appears now to be obsolete. The issue now is whether or how White continues to push along. There is some curious aji in the corner.


[Diagram]
Diag.: Pushing line (continuation)

White 1 here is normal, with a and b also having been played. Black responds at c or d (but not hane [1]). White in the latter case then closes off the open skirt or gets ahead with the knight's move.


[Diagram]
Diag.: Hashimoto-Rin

Hashimoto Utaro-Rin Kaiho 1974-05-02 continued in this way, with Black 11 at a for a fight in the centre. Omitting 6 was tried in a recent Korean game.



[1] Black hane in response to White 1 was played by Christoph Gerlach 5d against Hans Pietsch in the 1996 Fujitsu Cup. White cut immediately.

After Black 2 we have transposed.


[Diagram]
Diag.: Kim's variation

Seong-june Kim 6d gives this variation. This looks bad for White, unless there is some corner aji to use.

Diag.: Korean book analysis

A Korean book considers this possible situation, with Black 8 avoiding being shut in rather than attending to the corner.
