o18 looks like the move to me, i don't see how white can kill black after that but i maybe mistaken.

Black can't play o18 because white would play p17 and escape.
I don't see a way for black to survive without inferior play from white.

How about the sequence below? All White's responses seem forced to prevent Black making a second eye. Black next connects at 'a' and has broken out. The key point is that there isn't space for a second eye in the corner but there seems to be just enough potential that Black can use to drive White along the way.

Dave's reply seems to work.
This also occurred to me:
Next black plays at a, sacrifices some bits and gets a living shape in the corner. White has other replies e.g.
Next: And black seems to get a ko at least, so Dave's line is cleaner.

Looks a bit like the 19-point trick play to me... Black gets a reasonable number of points in the corner, but white has forcing moves to seal him in painfully.

and then takes two moves on the left to force black to play inside for the semeai, and white seals black in sente.Re: Go problem from my game tonight

Did you forget that in the 19-point trickplay both sides have played the same number of moves, but in this one white has 6 more stones?skydyr wrote: Looks a bit like the 19-point trick play to me...
