Tsumego From Games 56

  Difficulty: Advanced   Keywords: Life & Death, Problem

From a game between two 4D on KGS. Among the spectators, the question arose of how to respond to White a. Is a response necessary? If so, where should Black respond.

Dieter: Yes, Black should respond, and b suffices. The question for me is if c is also possible.

Velobici: During the game one suggestion was W a, Black d, White b, Black e.

Dave: You mean 1 - 4 here? Then W5 threatens a double atari at a. B6 prevents this but W7 is then seki. Note that if Black plays 6 at a, W7 kills Black.

Velobici: Indeed, the seki was one of the proposed results of the position in the kibitz discussion during the game.
