Zappa versus Rybka 2007,
was a 10 game computer chess match between Zappa and Rybka, held from September 20 to 27, 2007 as frame program during the final of the World Chess Championship 2007 in Mexico City, Mexico. The match was scheduled after Rybka author Vasik Rajlich made a $100,000 publicity challenge in May 2007 to the FIDE, to play the winner of the Deep Fritz versus Deep Junior 2007 match, Deep Fritz or Deep Junior, even offering odds of a game in a 24 game match [2] [3], but negotiations between Rybka and Junior teams broke down due to disputes over on-site machines [4] [5]. David Levy served as arbiter. Zappa, operated by book author Erdogan Günes won by 5½–4½ and the prize money of $10,000. A key game was the 180-move fourth game, where Erdogan, who smelled a weakness, insisted on playing on after a draw offer by the Rybka team. Due to the fifty-move rule, Rybka gave a pawn to avoid an immediate draw, and later two more pawns to eventually lose the game and match.
