Beginner Exercise 232 / Solution

Sub-page of BeginnerExercise232
White kills.  

W1 hits the vital point. Now a and b are miai for the kill...

Black should not play either a or b now, since both are utterly useless. However, either move can be used as a ko threat later. If black plays one and white ignores it because the ko is more important, black plays the other and saves the otherwise dead group.

Continuation 1.  

If Black makes an eye with B1, W2 connects outside, leaving Black with only one eye.

Continuation 2.  

If Black forms an eye with B1, White proceeds to falsify the other eye with W2 and W4.

White failure.  

Playing atari with W1 results in a ko, which is not the best result for White.
