39th Chess Olympiad

The 39th Chess Olympiad, organised by FIDE and comprising an open and a women's tournament, as well as several other events designed to promote the game of chess, took place from September 19 to October 4, 2010 in Khanty-Mansiysk, Russia. There were 148 teams in the open event and 115 in the women's event. In total, 1306 players were registered.

This was the fourth time Russia organized the Chess Olympiad after 1956 (Soviet Union), 1994, and 1998. Six cities had submitted bids to organize the Olympiad: Khanty-Mansiysk, Budva, Buenos Aires, Poznań, Riga, and Tallinn. The selection was part of the FIDE Congress held during the 37th Chess Olympiad in Turin in 2006.

The main events in both competitions were held in indoor tennis courts, which opened in September 2008. With an area of 15,558 m², it hosted 3,500 chess fans.

Both tournament sections were officiated by international arbiter Sava Stoisavljević (Serbia). For the second time, the number of rounds of the Swiss system was 11 with accelerated pairings. Both divisions were played over four boards per round, with each team allowed one alternate for a total of five players. The final rankings were determined by match points. In the event of a draw, the tie-break was decided by 1. Deducted Sonneborn-Berger; 2. Game points; 3. Deducted sum of match points.
