Gokyo Shumyo, Section 1, Problem 73 / Solution

Main line: HashimotoUtaro
Variations: Dieter


[Diagram]
Main line  

B3 is tesuji, and so is B5. If W8 covers at B5, Black captures seven stones at a.

[Diagram]
Variation at 6  

Capturing at B7 obviously makes life.

[Diagram]
Variation at 4  

W4 creates shortage of liberties for himself.

[Diagram]
Variation at 2  

W2 here doesn't work because of B7 atari.


Failures

[Diagram]
Failure at 1  

The crude play of B1 destroys all possibilities and White links up. If B5 is to the left of W6, then White plays at the point B5.

[Diagram]
Failure at 3  

This is essentially the same crude play as in the previous diagram.

[Diagram]
Failure at 5  

Omitting the atari of B5 at W6 and cutting right away with B5, again gives White the necessary liberties.
