Capturing Race Exercise 3 / Solution

[Diagram]

Solution

The solution is W1. Black is captured cleanly without ko.

[Diagram]

Solution

If B2 connects, then W3 wins the capturing race by one move.

[Diagram]

Solution

For B2 here, W3 results in a snapback.

[Diagram]

Failure

The atari at W1 here allows B2 to start an approach ko. Although this ko is favourable to White, but it is still a ko and not unconditional life, so we consider it a failure for White.

[Diagram]

Failure

The throw-in at W1 is worse. After B2, it is either seki or direct ko.
