36th Chess Olympiad

The 36th Chess Olympiad, organized by the Fédération Internationale des Échecs (FIDE) and comprising an open and a women's tournament, as well as several events designed to promote the game of chess, took place between October 14 and October 31, 2004, in Calvià on the Spanish island of Majorca. There were 129 teams in the open event and 87 in the women's event. In total, 1204 players were registered (some of whom did not play, though).

Both tournament sections were officiated by international arbiter Ignatius Leong (Singapore). Teams were paired across the 14 rounds of competition according to the Swiss system. The open division was played over four boards per round, whilst the women's was played over three. In the event of a draw, the tie-break was decided by 1. The Buchholz system; 2. Match points; 3. The Sonneborn-Berger system; and 4. The Median Buchholz system.

The time control for each game permitted each player 90 minutes for all their moves, with an additional 30 seconds increment for each player after each move, beginning with the first.

The open division was contested by 129 teams representing 125 nations. Spain, as hosts, fielded three teams, whilst the International Braille Chess Association (IBCA) and the International Physically Disabled Chess Association (IPCA) each provided one squad.

Led by first board Vasyl Ivanchuk, the seventh highest-rated player at the tournament, who recorded 9½ points over 13 rounds, and second reserve Sergey Karjakin who, aged just 14 years, won 6 of his 7 games (surrendering a draw only to American Gregory Kaidanov), Ukraine scored all four possible points in each of their first three matches before "only" defeating Russia 2½-1½ in the fourth round, eventually accumulating a nearly insurmountable three-point lead after the penultimate round. The Ukrainian team nevertheless scored three points against France and claimed their first title, three points ahead of Russia, who had entered the tournament as the top seed, having brought four of the tournament's nine highest-rated players, and as defending six-time champions.
