detecting cheaters


chess.com's exact cheat detection process is private information, but I can assure you it is much more advanced than just checking winrate. If you win a lot, then you have nothing to worry about if your games were played fairly. For future reference, please don't discuss cheating in the public forums though; we prefer any discussions related to cheating to be kept in this chess.com club:
