World's Best Chess Engine Outlawed and Disqualified

An anonymous reader writes "Rybka, the winner of the last four World Computer Chess Championships, has been found guilty by a panel of 34 chess engine programmers of plagiarizing two open-source chess engines: Crafty and Fruit. The governing body of the WCCC, the International Computer Games Association, is even demanding that Rybka's author — the international chess master and MIT graduate Vasik Rajlich — returns the trophies and prize money that he fraudulently won. Rybka will no longer be allowed to compete in the World Championships, and the ICGA is asking other tournaments around the world to do the same."
