Weiqi Gaoji Jieti Xunlian, volume 2, problem 55.
What puzzles me is not the problem, but rather the second fo the two correct answers shown in the book.
Makes sense. and are sacrifice stones to wring out the eye space within the black group.
unkx80: in this diagram is as funny as answer #2, isn't it death in gote?
But why in place of capturing at a ? Seems to me that after , Black can capture three white stones by playing at b. Why give up the three stones ?
Andrew Grant: Why not, as long as Black dies? White isn't actually losing points by letting Black capture the three stones. White gains three points by virtue of the fact that when the white stones come off the board the three points vacated become part of White's territory. The end result is the same.
Xanthus: What puzzles me is and in the solution. It seems to me like white can tenuki after and black is still dead, am I missing something?
unkx80: I think so too.
