A chess tournament is a series of chess games played competitively to determine a winning individual or team. Since the first international chess tournament in London, 1851, chess tournaments have become the standard form of chess competition among multiple serious players.
Today, the most recognized chess tournaments for individual competition include the Candidates Tournament and the Tata Steel Chess Tournament. The largest team chess tournament is the Chess Olympiad, in which players compete for their country's team in the same fashion as the Olympic Games. Since the 1960s, chess computers have occasionally entered human tournaments, but this is no longer common.
Most chess tournaments are organized and directed according to the World Chess Federation (FIDE) handbook, which offers guidelines and regulations for conducting tournaments. Chess tournaments are mainly held in either round-robin style, Swiss-system style or elimination style to determine a winning party.
