Beginner Exercise 222 / Solution

Sub-page of BeginnerExercise222

B1 is the only solution, setting up a ko for the life of the black group. If Black wins, he will capture white+square, making two eyes (well... three, actually).


B1, hoping to catch the white stones in a connect and die, is a failure. After W2 Black cannot play atari at a because of shortage of liberties. B1 at a, W2 fails similarly.

Two stage ko  

Bill: Black can live by capturing white+square, but that should be a last resort. This is properly a two stage ko. Black should normally play to win it with B3 and B5.
