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 serious players.
Today, the most recognized chess tournaments for individual competition include the Linares chess tournament (now defunct) 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 1950s, chess computers have even begun entering the tournament scene.
Most chess tournaments are organized and ruled 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.
Although modern chess had been established since around 1475, the first tournament (in the sense of structured competitions) was in Leeds in 1841. There was a knockout tournament in London in 1849 and a tournament in Amsterdam in 1851. The first international chess tournament was held in London in 1851. The London 1851 tournament took place during The Great Exhibition, and would serve as a guide for future international chess tournaments that would follow it. The tournament not only showed the need for time controls but it also clearly demonstrated the drawbacks to the knockout elimination tournament format. It was won by Adolf Anderssen of Germany, who became regarded as the world's best chess player as a result.
