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 heavy for White, although conventional wisdom tells us that the ko is heavier for Black. The reason is that 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.
