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 organised 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.

As a sporting federation recognized by the IOC, and particularly as a signatory to the World Anti-Doping Agency (WADA) conventions, FIDE adheres to their rules, including a requirement for doping tests, which they are obligated to take at the events such as the Olympiad. The tests were first introduced in 2002 under significant controversy, with the widespread belief that it was impossible to dope in chess. Research carried out by the Dutch chess federation failed to find a single performance-enhancing substance for chess. According to Dr Helmut Pfleger, who has been conducting experiments in the field for around twenty years, "Both mentally stimulating and mentally calming medication have too many negative side effects". Jan Timman and Robert Hübner either refused to play for their national team or to participate in events such as the Chess Olympiad where drug tests were administered. All 802 tests administered at the 2002 Olympiad came back negative. However, in the 36th Chess Olympiad in 2004, two players refused to provide urine samples and had their scores cancelled. Four years later, Vasyl Ivanchuk was not penalized for skipping a drug test at the 38th Chess Olympiad in 2008, with a procedural error being indicated instead. In 2010, a FIDE official commented that due to the work of the FIDE Medical Commission, the tests were now considered routine. In November 2015, FIDE president Kirsan Ilyumzhinov announced they are working with WADA to define and identify doping in chess. ==Competition==

Each FIDE-recognized chess association can enter a team into the Olympiad.). Initially each team played all other teams but as the event grew over the years this became impossible. At first team seeding took place before the competition, with teams playing in preliminary groups and then finals. Later certain drawbacks were recognized with seeding and in 1976 a Swiss tournament system was adopted. Starting from 2008, the first criterion for determining ranking has been match points instead of board points. Teams score 2 points for a match win, 1 point for a drawn match and 0 points for a match loss. The trophy for the winning team in the open section is the Hamilton-Russell Cup, which was offered by the English magnate Frederick Hamilton-Russell as a prize for the 1st Olympiad (London 1927). The cup is kept by the winning team until the next event, when it is consigned to the next winner. There is a separate women's competition. Since 1976 it has been held at the same time and venue as the open event, with the two competitions comprising the Chess Olympiad. The trophy for the winning women's team is known as the Vera Menchik Cup in honor of the first Women's World Chess Champion. Judit Polgár from Hungary is the only player who won Chess Olympiad medals in both competitions – two gold medals in the women's event (1988, 1990) and two silver medals in the open event (2002, 2014). ==Results (open event)==

Russia won this trophy six times, China – three times, India and Ukraine – two times each. ==Medal tables==
