Beginner Exercise 49 / Solution

Solution

The solution is to capture at B1.

[Diagram]

Black lives

If White tries to escape with W2, then Black B3 makes two eyes and lives.

[Diagram]

White captured I

White cannot escape now.

[Diagram]

White captured II

White cannot play inside anymore and Black is alive.


[Diagram]

Black still lives

Even with an additional stone helping White to connect, Black lives.


[Diagram]

Failure I

The connection at B1 is a failure, because after W2, Black has only one eye.

[Diagram]

Failure II

Directly preventing the WC stone from connecting is also a mistake. After W2, White dies with a farmer's hat big eye dead shape.

[Diagram]

Failure III

If B1 here, W2 sets up a ko which Black must win in order to live. Since Black can live unconditionally, this is not the best result .
