Beginner Exercise 31 Solution
  Difficulty: Beginner   Keywords: Problem

lavalyn says that unkx80 is starting to make the problems a little harder than "beginner" as Beginner Exercises should be.

[Diagram]
Diag.: Atari at 1

White prepares to connect with the corner and make an eye there. Because Black is in atari his response will be one of the two labelled points.


[Diagram]
Diag.: Variation a - Black 4 at marked point

White lives after this sequence to White 7 - one eye in the corner.


[Diagram]
Diag.: Variation a, Subvariation 1 - Black 4 at the square mark, White 11 at the circle mark

Should Black choose to resist in making the easy corner eye, two eyes form in the corner.


[Diagram]
Diag.: Variation a, Subvariation 2

Throwing in doesn't work either. White will live again.


[Diagram]
Diag.: Variation b, Subvariation 1 - Black 6 at marked point

White constantly keeps the Black stones in atari and thus can make all her moves in sente until 7, by which time White is unconditionally alive.


[Diagram]
Diag.: Variation b - Subvariation 2

Black's stubbornness in keeping the two groups disconnected yields the death of the blockading group.
