Thick Plays In The Endgame/ Discussion

Bildstein: Would I be right in assuming that B1 is shobute in the sense that Black is hoping that White will protect the bottom right corner instead of capturing B1 (after B7), but then when White does capture B1 instead, he is refuting B1? Or did Black make up some ground in this game with his shobute of B1?

Mef: As I understand if, B1 is shobute because it tends to lead to an unclear position, and black being behind would prefer an unclear position. Since White is ahead, it is to his benefit to simplify, so he can play a move that costs him some points (namely W1 in the second diagram). While this move loses some points for white, the resulting position is much more clear and Black has no more aji he can use to try and make up the rest of the difference.

Black's fight 1  

Dave: According to Sakata Black plays the marked stone hoping to mix it up. If White plays the hane underneath at W1 here, Black will cross cut with W2 and stake the game on the ko fight after B8. Note that White can not simply capture the cutting stone because Black will connect at 5 having broken into the side.

Black's fight 2  

Dave: If White plays the hane on top at W1 here instead, Black will again cross cut. Now Black views a and b as miai.

White's answer 1  

Dave: White's answer at W1 in the game denies Black the fighting sequences above. If Black plays B2 here, White answers calmly with W3 - W7 and Black is lost.

White's answer 2  

Dave: If instead Black plays this B2, White calmly connects at W3 and now a and b are again miai but this time for White.
