Also, i think fruit has some time management issues when you use an increment (it seems to really save time a bit). I am not sure exactly at what time increment fruit starts to do fine. I 've tested it on a single computer at 15 min 10 secs and it was strong there. Maybe it only struglles in bullet. I must say I am surprised by fruits poor performance at very short intervals. I wonder if fruit does something like clear out the hashtable between each move and maybe this causes it some problems in really short time controls. Or, the chessbase interface my still be turning off its history pruning and this is why it does badly at very short intervals. Anyway, bullet time controls (under two min) are not terribly meaningfull anyway. Fruit is clearly one of the best programs around
