A chess tournament is a competitive event where players face off in a series of games to determine a winner. These tournaments can vary in format, including knockout, round-robin, or Swiss system, and can be held at local, national, or international levels. Participants often include amateur and professional players, and they may compete for trophies, cash prizes, or titles such as Grandmaster. Tournaments are usually organized by chess clubs, federations, or online platforms. Players are typically required to register in advance, and games are played under specific rules governed by the World Chess Federation (FIDE). Spectators can often watch the matches live or online, making chess tournaments accessible to a wider audience.
