Beginner Exercise 21 Solution

Diag.: White escapes!

Black is caught in connect-and-die. If black 'a', white 'b' captures. Otherwise, white captures at a, and is connected to the outside and escapes, thus living (by tsumego convention).

Diag.: White failure

The double atari is wrong here: black chooses which group to sacrifice, preventing white from connecting and escaping. Note the the bottom row of four is good for at most one eye. After white captures (perforce; if white tries to start making an eye below, black will capture and white only gets one eye), black reduces that to no eyes with the double hane:


[Diagram]
Diag.: White failure (con't)

White again has only one eye.
