Beginner Exercise 177 / Solution

Solution

[Diagram]

Solution

First, W1 makes a tiger shape, and then W3 throws-in to make a ko.

[Diagram]

Comment

Note that this ko is fairly lopsided: if White loses the ko, the loss is quite substantial.

[Diagram]

Variation

If B2 prevents the ko, then W3 destroys the eye and kills.



Failure

[Diagram]

Failure

The descent at B1 fails. The cut at B2 is tesuji, and Black gains sente to live at B4. Now White cannot approach at a and capture the three Black stones.

[Diagram]

Failure

W3 here is useless.

[Diagram]

Failure

The connection at W1 fails. After B2 makes the second eye, White is unable to play at a, so Black wins the capturing race at the top.

[Diagram]

Failure

B2 captures the stone at the corner and lives.
