Kyu Exercise 4 Solution
  Difficulty: Advanced   Keywords: Life & Death, Problem

Solution 1

[Diagram]
Placement on the second line.

The simpler solution would be a placement on the second line. B3 forces W4, and B5 reduces the eye at the bottom to one in sente.


[Diagram]
Placement on the second line.

Why sente? Because if White obstinately makes the other eye with W6, Black captures White with B7.



Solution 2

[Diagram]
Placement on the first line.

The placement at the first line also works, but B3 and B5 are probably a blind spot.


[Diagram]
Variation.

If W2 simply captures the two Black stones, Black can simply set up a snapback with B3 and B5.


[Diagram]
Failure.

B3 is incorrect. Although B5 is a ploy to reduce the eye in sente, but W6 answers correctly and lives.


[Diagram]
Failure.

B9 and W10 are miai.



Other variations

[Diagram]
Atari.

The atari at 1 is a mistake.


[Diagram]
Atari.

Black makes a throw-in at B5, but White occupies the vital point of the bulky five with W6 and lives.
