Deep Thought easily beat Cray Blitz every time >we played (except for the first, where we could have won had we not run into >a serious bug). Cray Blitz waxed Crafty in a 10 game match last year. >That means _you_ should be able to wax crafty on my quad xeon easily if you >could crush deep thought. > >Let me know when you are ready to "take the test". > >I don't believe you can do it for a minute... > >But the ball is in your court to accept the challenge... 1)Deep thought did not beat the same cray blitz that beated crafty. The cray blitz that beated crafty could search more nodes per second thanks to better hardware. 2)The time control of the games crafty-cray blitz was not 120/40 and I suspect that at 120/40 crafty could do better thanks to better search rules(cray blitz used R=1 when Crafty is using R=2/3 for null move pruning) 3)Winning is also not transitive so even if you were right it was not a proof. 4)The result btween deep thought and cray blitz does not prove that deep thought was better. Junior was leading 5-0 against Fritz and lost the match 14-12 so using a small number of games when in one of them cray blitz could win is not a convincing evidence. Uri
