Allo, >Dr. Tinsley '94 and Chinook '94 were about equal. It's tough to compare Dr. >Tinsley '57 and Chinook '00 though. Exactly :P I don't think we will ever know the answer to this.. or the answer to what if Tinsley was alive now, in his prime, and had the benefit of all of the new knowledge that is available.. >I don't know why you say that the top human players can still beat it once in a >while. Please cite the game. My understanding is that it hasn't lost a game >since the last time Tinsley beat it. It has since clobbered both the reigning My burden of proof here is to find one game, and within 3 minutes of looking, I found one :P I'm sure that with more digging, more such games could be found. Lafferty vs Chinook (1994, Boston, after the Tinsley vs Chinook match which Tinsley bowed out of due to sickness): +1 -1 =18 FYI, Lafferty currently (as stated by the web page when looking at the bio for him) has a winning record against Chinook. You can see a lot about Chinook at: http://www.cs.ualberta.ca/~chinook/ And in particular, match info at: http://www.cs.ualberta.ca/~chinook/matches.html >human world checkers champion and the reigning human world correspondence >checkers champion. We're talking +8 -0 =12 types of scores, and checkers is >much more drawish than chess. I don't think it's quite that severe - I would guess that if Chinook were to play the best ranking player in the world who was prepared for such a match a long series of games, I would expect to see something like this: Chinook wins: 20-25 % of the games Chinnok losses: 5-10 % of the games Draws: 65-75% of the games Adrien.
