Here's a small sample of A 40/2 Standard Rebel 9 tournament 4.5 - 0.5 against an average field of 2312(Fide) Dominican Republic Rebel 9 played 5 Fide Rated opponents at 40/2 then all/1 hr. on a P-225 Eddy De Los Santos (2190) 1-0 Jose M. Dominguez (FM 2305) .5-.5 Gustavo Hernandez (2320) 1-0 Nelson Pinal (IM 2330) 1-0 Ramon Mateo (IM 2415) 1-0 TPR =Rc+400(W-L)/N TPR=2312+400(4)/5 TPR=2632 Note: this tournament was 11 rounds. Rebel defeated Hiarcs and drew CM5000 in this tournament. It also defeated 4 other participants who do not have a fide rating, for a first place score of 10/11. Alone this tournament lacks the data pool size for the usual proclamation, "It's rating must therefore be 2632". However if you toss into the mix the 24 games from Aegon, even including the 1994 Rebel 6 result on a measly 486, the result is still a performance rating of over 2500. Now we have 2 more games against a 2795 rated player. That's over the min 25 we use for ourselves. Deep Thought was given this 25 game limit years ago to calculate its plus 2500 rating. Don, your Cilkchess was at Aegon in 1997. You must have been pleased that it drew its game with GM Seirawan. His comments after were also interesting. He expressed that he was bothered with his game because he missed a better continuation. To me it sounded like he took the game very seriously. My last sentence may be redundant - is there such a thing as a chess player not playing seriously to win each and every game they play? :) >You don't want Rebel >playing up in every game, or visa versa.

I still think >it's too early to go after the GM's. I fear the GM population will not be that anxious to play the computers not for any profound reason other than it interferes with their main focus. That is getting better at their game, defeating humans, winning tournaments and getting prize money. But from a related previous post someone said cash will draw them out of the woodwork to play computers - this I agree with and I also think it is a reasonable expectation. Hopefully there will be some GM's who take up the gauntlet and play match games simply for the sake of curiousity in discovering what these machines are capable of. Didn't Crafty have a go at Yermolinsky at a long time control? What happened there?
