aloha! while kramnik-DF was going on, it became rather clear during the first 4 games that fritz was not doing well in simplified positions. some people here suggested that fritz was "under par" in endgames, when compared to other engines, and that other programs would have done better in the kind of positions kramnik was going for. at that point i got the idea for the "kramnik match", which would be the same thing as the nunn match, only starting out in those "boring" queenless middlegames that kramnik used to play against fritz. naturally, i was hoping for more than 4 positions to start with, but unfortunately (for this purpose), the fritz team avoided these positions in the later games. so the "kramnik match" that i propose here is very (too?) short, and probably only meaningful as a tournament with a couple of engines. i don't have any free or decent machines to play computerchess with, and i don't have any other commercial engines except fritz, so i played a tournament with fritz 7, ruffian 1.00, crafty 19.01 and yace berlin on blitz level (4' + 2'') on my P3-450 laptop with this result (interface: fritz 7, no tablebases, 64MB hash each): 1 Fritz 7 ******** 1½½101½½ ½10110½½ 11½11½11 16.5/24 2 ruffian 0½½010½½ ******** ½0½½1½1½ 011½0101 12.0/24 3 Crafty 19.01 ½01001½½ ½1½½0½0½ ******** ½01½1½½½ 11.5/24 4 yace 00½00½00 100½1010 ½10½0½½½ ******** 8.0/24 i've pasted the PGN file i used for the match at the end of the post - i just started off at the point where the queens were exchanged in games 1-4. obviously, a blitz tournament (and on a slow machine on top!) is not too meaningful, and 24 games is not very much. but perhaps some of you have more computer resources, more experience with computer tournaments, and more (commercial) engines to give this a try! if i had to conclude anything at all from this tournament i would say that fritz doesn't look bad at all, winning overall, and winning every single individual match... cheers martin [Event "Brains in Bahrain"] [Site "Manama BAH"] [Date "2002.10.04"] [Round "1"] [White "DEEP FRITZ"] [Black "Kramnik,V"] [Result "1/2-1/2"] [BlackElo "2807"] [EventDate "2002.10.04"] [ECO "C67"] 1. e4 e5 2.
