A few addtional answers, and one more test for the crucial lower left
corner.

Not sure I agree here. L13 is sente and the difference of not playing it
is too big to just give it away.
If GNU Go would play L11 next move, the capture would be clean. And of
course it has several chances later...

H7.

Maybe F10.

D11. Btw, locally I think P18 is tolerable. (It does capture everything,
and pretty cleanly.)

How about:

loadsgf games/olympiad2004/19x19/gnu-ind.sgf 237
??? reg_genmove black
#? [A7]

This makes black alive locally.
