Beginner Exercise 31 / Solution
Sub-page of BeginnerExercise31

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

heresiarch: What threw me on this problem was my desire to kill the black farmers hat group - which I couldn't for the life of me divine a suitable method. It doesn't say "white to kill," which for an astute player should suggest other outcomes, but for a new player like myself in a groove from the last few exercises, all I want to do is kill. Perhaps a note on the problem like "White to continue for life" or "White to continue" with a link to possible outcomes of exercises like this.

When figuring out real game problems, it's been useful for me to remember that my three options are killing attackers, making life, or connecting/running. Reminding that all options are viable in real games and are thus important to consider in these problems might also be a good idea.

[Diagram]
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]
Variation a - Black 4 at marked point

White lives after this sequence to W7 - one eye in the corner.


[Diagram]
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]
Variation a, Subvariation 2

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


[Diagram]
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 W7, by which time White is unconditionally alive.


[Diagram]
Variation b - Subvariation 2

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