Answer To Last Month's Problem

British Go Journal No. 66. [1] November 1985. Page 31a.

The problem for this solution is on page 31 of BGJ 65 [2].

Diagram 1





Diagram 2





The symmetry of white 1 should have helped readers find this move. White 1 in Dia 1 prevents black 1 in Dia 2, which forces white to reduce his eyespace with 2. After black 3 white can no longer make living eye shape.

Diagram 3





If black still tries to kill white, with EG 1 in Dia 3, white 2 lives easily because of the extra internal liberty. Note, however, that white cannot play at A in reply to black 1. Black blocks at 2 and can make the dead "rabbity-six" shape - (see the "Life & Death" Elementary Go Series book).
[White has life in seki.]
