Vasik Rajlich

Vasik Rajlich (born 1971 in Cleveland, Ohio) is an International Master in chess and the author of Rybka,[1] one of the strongest chess playing programs in the world.[2][3][4][5][6] 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.[7]

He married Iweta (née Radziewicz) on 19 August 2006. Iweta, who is also an International Master in chess,[1] helps him with the development of Rybka as its tester.[8] In April 2012, the couple was living in Budapest, Hungary and had one child, a son.[8][9]

In April 2012, Rajlich participated in an April Fools Joke that claimed that he had proven to a 99.99999999% certainty using Rybka that the King's Gambit is at best a draw for white.[9]

Rajlich's handle on the Internet Chess Club is "vrajlich".[10]

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.[11] 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.[12] Vasik Rajlich is banned for life from competing in the WCCC or any other event organized by or sanctioned by the ICGA.[13] Rajlich had already responded to these charges with an 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[14] ”
