There are various systems of Go ranks and ratings that measure the skill in the traditional board game Go. Traditionally, Go rankings have been measured using a system of dan and kyu ranks. Especially in amateur play, these ranks facilitate the handicapping system, with a difference of one rank roughly corresponding to one free move at the beginning of the game. This system is also commonly used in many East Asian martial arts, where it often corresponds with a belt color. With the ready availability of calculators and computers, rating systems have been introduced. In such systems, a rating is rigorously calculated on the basis of game results.

Cheating in chess is a deliberate violation of the rules of chess or other 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 after a game. Commonly cited instances of cheating include: collusion with spectators or other players, use of chess engines during play, rating manipulation, and violations of the touch-move rule. Many suspiciously motivated practices are not comprehensively covered by the rules of chess. On ethical or moral grounds only, such practices may be judged by some as acceptable, and by others as cheating.

A chess rating system is a system used in chess to estimate the strength of a player, based on their performance versus other players. They are used by organizations such as FIDE, the US Chess Federation, International Correspondence Chess Federation, and the English Chess Federation. Most of the systems are used to recalculate ratings after a tournament or match but some are used to recalculate ratings after individual games. Popular online chess sites such as chess.com, Lichess, and Internet Chess Club also implement rating systems. In almost all systems a higher number indicates a stronger player. In general, players' ratings go up if they perform better than expected and down if they perform worse than expected. The magnitude of the change depends on the rating of their opponents. The Elo rating system is currently the most widely used.
