This is a whole board collapse but unless someone makes the effort to localize exactly where the position collapsed sometime soon I'll close it as wontfix.

I replayed this game using the latest CVS, and there are a number of places where gnugo plays differently. The first occurrences being at moves 1 and 24. I think maybe this should be marked as fixed, or at least resolved.

Move 1 depends on the random seed and a difference there is irrelevant. Move 24 is for the opponent but it's quite possible that black's position was already hopeless about that time.

Looking at this again, I believe move 9 (black D4) is questionable. At this point in the game, black needs to be more aggressive. With --monte-carlo and a higher level set, gnugo finds E7, which would be better.
