Kyu Exercise 5 / Solution

Sub-page of KyuExercise5

Main line

[Diagram]
Main line (6 at 3).  

The sequence of B1 and B3 is the key. Note that if Black captures the three white stones, the group will get a second eye and lives.

Main line (4 at marked atone).  

The rest is atari all the way.

Which ends in a shunt after B1. Ironically, the white+circle stone appears to be at a very beautiful position but does not help White at all.



Variations

[Diagram]
Variation 1.  

If W2, Black lives simply by atari at B3 and B5.

[Diagram]
Variation 2.  

Same case.

[Diagram]
Variation 3.  

The jump at W2 will only cause the entire chain to be captured.



Failures

[Diagram]
Failure 1.  

The direct atari at B1 does not work.

[Diagram]
Failure 2.  

The sequence of B1 and B3 is wrong. After W4, Black is dead.

[Diagram]
Failure 3 (8 at 5).  

The smart aleck move at B1 will only remove White's weakness.
