Fair play

Fair play is the principle that competition should proceed honestly, under equal conditions, and according to the rules. In chess, each player should make independent decisions, results should represent genuine games, and nobody should gain an advantage through prohibited help or manipulation.

The idea is therefore broader than avoiding cheating. It also includes cooperating with arbiters and reasonable controls, following event procedures, and reporting concerns through responsible channels. Those procedures should in turn protect confidentiality, examine evidence, and provide an opportunity to respond or appeal when applicable.

Specific measures differ between over-the-board play, supervised online competition, and informal platform games. The governing rules define matters such as permitted devices, cameras, identification, and monitoring. The shared purpose is to preserve the game's genuine uncertainty and confidence in the result.
