Black to play.

After B1, White is left without two eyes.



B1 threatens to capture the three white stones to the left of B1. White can not form two eyes without these stones. White must connect these stones to the rest of the White group using a or prevent Black from capturing these stones by playing b. b makes a Black attempt to capture the stones by playing at a a self-atari.

Unfortunately for White, neither White a nor White b make life.

It is Black's move. He will destroy White's potential eye on the right with B3.

The key to the problem is the first rule of killing groups: Examine a play at the eye-point.
