Rybka

Rybka leads every major rating list by at least 60 Elo and has taken unshared first place in ten out of the eleven major international tournaments in which she has participated, including the 2007 ICGA World Computer Chess Championship and the 2007 Livingston World Computer Chess960 Championship. In addition, she has won three matches giving handicaps to prominent grandmasters.

She most commonly plays her games in a natural, classical style, logically and consistently exploiting positional trumps and leaving the viewer with the impression that chess really is quite simple.

The US international master Vasik Rajlich is the inventor and main developer. He has been joined by another US international master, Larry Kaufman, himself a former computer chess author, who has taken over work on Rybka's evaluation function. The Rybka opening book effort is headed by the long-time Dutch computer chess opening specialist Jeroen Noomen, who is assisted by the Danish opening and computer chess specialist Dagh Nielsen.


Zappa is a chess engine, or a program that plays chess. It is similar to Deep Blue - only much better - and is best known for its good parallel speedup. It has competed in many computer chess tournaments with its best result coming at the World Computer Chess Championship in 2005, where it took first place with the score of 10.5/11, the best result in the history of that competition. Written by Anthony Cozzie (the USA ), a PhD student in computer science, Zappa contains many advanced techniques from the fields of artificial intelligence and parallel programming.

The latest game, number 6 I believe, was a definite yawn. Looks like an exciting game when you play through it, until you are told that zappa played all that in home preparation stuff, right until move 33 or so.

I was watching it and both sides still had 55 mins on their clock after move 35. Time control of 60 mins + 20 secs per move.

Aren't they due to play game 10 today? I believe the score is 5-4 Zappa.
