Alive

Black is alive... or more correctly, mostly alive.



Analysis

[Diagram]

White's best play

For White, W1 is best. B2 forms a bent four and lives, and White can play at a to capture the stones at the corner.

[Diagram]

Weak attack

W1 and W3 is a weak attack, B4 lives easily.

[Diagram]

Black's tesuji

W1 and W3 is probably the strongest attempt to kill. The main thing to see in this problem is the tesuji at B4, which makes W5 and B6 miai for life.

[Diagram]

Black's failure (9 at 7)

B4 is wrong. White makes a placement at W5, followed by an atari at W7 on the entire Black group which forces B8 to capture, finally a throw-in at W9 which makes the eye at the corner a false eye.
