Pushing battles in joseki 8
Difficulty: Dan level
Keywords: Joseki
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:
Naturally with a bad ladder White 5 will set up a net instead.
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.
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.
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.
Seong-june Kim 6d gives this variation. This looks bad for White, unless there is some corner aji to use. Pushing Battles in Joseki 8 Corner Aji Discussion: what can White do in the corner now?
A Korean book considers this possible situation, with Black 8 avoiding being shut in rather than attending to the corner. This is a copy of the living page "Pushing battles in joseki 8" at Sensei's Library. ![]() |
