High Quality Content by WIKIPEDIA articles! Cheating in chess refers to a deliberate violation of the rules of chess or other unethical behaviour that is intended to give an unfair advantage to a player or team. Cheating can occur in many forms and can take place before, during, or possibly even after a game. Commonly cited instances of cheating include: collusion with spectators or other players, linking to remote computers, rating manipulation, misuse of the touch-move rule, the pre-arranged draw, and the use of psychological tactics to unsettle an opponent. Many suspiciously-motivated practices are not comprehensively covered by the rules of chess and so, on ethical or `moral conduct` grounds only, may be judged by some as acceptable, and by others as cheating.
