Vasik Rajlich (born 1971 in Cleveland, Ohio) is an International Master in chess and the author of Rybka, previously one of the strongest chess playing programs in the world. Rajlich is a dual Czechoslovakian-American citizen by birth; he was born in the United States of America to Czech parents, at that time graduate students, but grew up in Prague. He later spent years in the United States as a student, graduating from MIT.
He married Iweta (née Radziewicz) on 19 August 2006. Iweta, who is also an International Master in chess, helps him with the development of Rybka as its tester. In April 2012, the couple was living in Budapest, Hungary and had one child, a son.
In July 2015, it was announced that the ChessBase Fritz brand's 15th version would be programmed by Rajlich, thus conglomerating the Rybka name into the best-selling Fritz brand. The release is timed for late October 2015. No details on Elo expectations were yet given.
WCCC disqualification and banning
On 28 June 2011, the International Computer Games Association (ICGA) determined that Rajlich had plagiarized two other chess software programs: Crafty and Fruit. The ICGA sanction for Vasik Rajlich and Rybka was the disqualification from the World Computer Chess Championship (WCCC) of 2006, 2007, 2008, 2009 and 2010. Vasik Rajlich is banned for life from competing in the WCCC or any other event organized by or sanctioned by the ICGA. Rajlich had already responded to these charges with a brief e-mail to David Levy, president of the ICGA, in which he stated:
|“||Rybka “does not include game-playing code written by others”, aside from standard exceptions which wouldn’t count as ‘game-playing’. [...] The vague phrase “derived from game-playing code written by others” also does not in my view apply to Rybka||”|
The FIDE Ethics Commission later upheld the ICGA (May 2015), saying that in disqualifying Rajlich "the ICGA has not violated the FIDE Code of Ethics, nor any other FIDE rule or general principle of law." They however were more critical of the banning for life, under application of Swiss law.
