     The best that black can do in this problem is to force a ko on white.
That is of course if white is bright enough not to kill himself off. Please
note that after black 1) A-2 if white plays at A-3 he dies and if he plays
elsewhere... black 3) B-3 is a snap back.

    Black must make the first ko threat but this is alright. This ko is so
large that white will most often allow black two moves somewhere else on the
board. Black can be happy no matter what the outcome!
