I had Crafty 15_18 play a blitz match (4 min + 2 sec inc) against the 1.21
Little Goliath update. In game 13 (ominous number?) of their match Crafty
blundered away a clear win. The Crafty twilight zone started on move 75 and
ended on move 77 after which the previously won position was a clear loss.
Little Goliath garnered an undeserved win and I was left completely in the dark:
hash-collision, tablebase problems??? Perhaps Bob Hyatt can help. Here's the
game. (Endscore 15-5 for Crafty)
PS: AMD-K6-II/300 128MB, 10 megs of hash for Crafty.
Regards,
Djordje
