A chess tournament is a competitive event where players face off in a series of chess matches to determine a winner. Participants can be individuals or teams, and the tournament may follow different formats, such as knockout or round-robin. Players earn points based on their performance, and the one with the highest score at the end is declared the champion. These tournaments can vary in size, from local competitions to international events featuring top-ranked players. Many tournaments are organized by governing bodies like the World Chess Federation (FIDE), which sets the rules and standards for play.
