About the tablebases, I disagree; having a more extensive tablebase means that you can short-circuit calculations earlier in the game (because you immediately know the evaluation if your calculation results in a tablebase position.) So it helps even if you don't actually end up playing into a six-or-less-piece endgame. It's obviously hard to say, but it's certainly conceivable that it hurt Fritz's play in a few of the games which wound up being drawn. I didn't mention it, but another condition of the match greatly favoring Kramnik was that the computer's opening book was completely open to him as well -- he could view all of Fritz's move weightings and statistics during the openings (an attempt at "fairness" given the computer's theoretically more extensive knowledge.) If you're not aware, Fritz is also no longer at the top of the heap in computer chess. http://www.rybkachess.com/ http://www.rybkachess.com/
