World Chess Olympiad

The World Chess Olympiad is a chess tournament where chess players from all over the world compete against each other. FIDE organizes the event and they select which nation will host the event.

Wikipedia gives this following explanation of the Chess Olympiad:

(The first Olympiad was unofficial. For the 1924 Olympics an attempt was made to include chess in the Olympic Games but this failed because of problems with distinguishing between amateur and professional players. While the 1924 Summer Olympics was taking place in Paris, the 1st unofficial Chess Olympiad also took place in Paris. FIDE was formed on Sunday, July 20, 1924, the closing day of the 1st unofficial Chess Olympiad.

FIDE organized the first Official Olympiad in 1927 which took place in London. The Olympiads were occasionally held annually and at irregular intervals until World War II; since 1950 they have been held regularly every two years.)

Each FIDE recognized Chess Association can enter a team into the Olympiad. Teams are made of up to six players, four regular players and two reserves. The trophy for winning the men's team is the Hamilton-Russell Cup and is kept by the winning team until the next event. The trophy for the winning women's team is the Vera Menchik Cup.
