Rybka 4 Released
Rybka has been the dominant force in computer chess for nearly five years, and despite some recent pretenders (possibly reverse-engineered clones), the "little fish" still sets the standard to beat.
The programmer, Vasik Rajlich has been tweaking his creation and has released the new improved Rybka 4.
Although computer ratings are determined by endless automated contests with other silicon beasts, there are also some real-life tournaments where the programmers get to swap notes and hang out while their engines lock horns for a few games.
The 10th International Computer Chess Tournament has just finished in The Netherlands, and Rybka once again took first prize with a very impressive 8/9 score.
