In June 2011, the [[ICGA]] has disqualified and banned [[Rybka]] and its programmer [[Vasik Rajlich]] from previous and future World Computer Chess Championships. The ICGA accuses Rajlich of plagiarizing two other programs, [[Crafty]] and [[Fruit]], and demands that he returns the trophies and prize money of the World Computer Chess Championships in [[WCCC 2007|2007]], [[WCCC 2008|2008]], [[WCCC 2009|2009]] and [[WCCC 2010|2010]] <ref>[https://web.archive.org/web/20160419082204/http://www.chessvibes.com/?q=reports/rybka-disqualified-and-banned-from-world-computer-chess-championships Rybka disqualified and banned from World Computer Chess Championships | ChessVibes] by [http://www.chessvibes.com/?q=peterdoggers [Peter Doggers]], June 29, 2011([https://en.wikipedia.org/wiki/Wayback_Machine Wayback Machine])</ref>, see [[ICGA Investigations]].
