We talk here about >crafty single cpu at 300k nps against an opponent at a million NPS. Crafty should have been able to find Nxe6. Why it didn't, I don't yet know. It seems that it was moving far faster than it should have. I can't reproduce the fast moves here, so it was something that happened in London. I may have given Graham a bogus command that screwed up the time control. He may have entered a time control wrong. I might have a program bug that asks for seconds but means minutes, somewhere. Until I know more, I don't have any idea why it would be moving in just over a minute. However, I would take the white position as a human, any day. Until someone convinces me that black wins no matter what. > >We don't talk about a few blitz games B01 or something at icc. > >We talk about WMCC and about Crafty versus Fritz where crafty >repeats a line which and loses chanceless, even though everyone >in this room felt it wasn't smart to repeat the same B99 mainline >as against Nimzo. > >Still finding Nxe6 doesn't solve the problem for you. > >You lose a few moves further then. I am not convinced of this, yet. I have seen Fritz make tactical errors. I have seen everyone make them. I don't think this is as clear as you imply it is...
