Subject: Human player blows Crafty 19.12 out of the water

I use crafty 19.12 on www.chessanytime.com and i was playing a user named
Pipoca,
he plays my computer a lot, loses everytime, not by much, but he loses, he lost
about 11 games to me tonight and drawed one.  But he did win one, the son of a
bitch won a game, and it totally blew crafty out of the water, its unbelievable,

10min blitz,
athlon 1700
48hash
and 8 for pawn hash


I'm not sure which move was the blunder for Crafty, but b2 just crushed it, eval
goes from 0.00 to -10.00 in only a few seconds, where could crafty have avoided
this terrible exchange?


its hard to say, lets hear some input from everyone,
he's definately human, as he has more blunders after the devastating pawn
exchange than any program ever could,
I feel that this was actually a blunder by crafty, although i can't find the
obvious move, it was obvious that the allowance of b2 was unwarranted.
