Rybka Proves It Is Still The Best

Congratulations to Rybka's creator, IM Vasik Rajlich, for raising the bar on the competition.

Rybka's creator, IM Vasik Rajlich

Rybka finished first in the 16th ICGA World Computer Chess Championship held in Beijing, China with a score of 8/9 with no losses. For much of the tournament Hiarcs was keeping pace with Rybka but when the two engines played, Rybka was victorious. The other key game for Rybka was against  Junior (2006 World Computer Chess Champion.) In this game Rybka seems to be aiming for a Kan or Taimanov Sicilian with the early a6 move. Junior responds with an early c3 and the game quickly becomes of interest to all players who enjoy the Kan, Paulsen, or Taimanov Sicilians.  Below is a list of all the past champions, followed by the 2008 results and the Junior vs. Rybka game.
