Irina Levitina

Irina is the only person in the world to win world championships in both chess and bridge. She has won five bridge World Championships, including all of the Women's events (Venice Cup, McConnell, Olympiad and Women's Pairs) as well as the Transnational Mixed Teams.

Especially well respected for her declarer play, Irina was one of 34 world-class players (including only 4 women) invited to participate in the World Par Contest, a declarer play competition, held in connection with the 1998 World Championships in Lille, France. In finishing 14th overall (and first among the women), Irina placed ahead of such stars as Benito Garozzo, Chip Martel, Steve Weinstein, and Zia.

Born in St. Petersburg, Russia, Irina was first taught chess as a young child by her father. By the age of 18 she was a member of the Soviet team and was the top woman at the chess Olympiad. At age 18, Irina also took up bridge, introduced to the game by Simeon Furman, her chess teacher (and Karpov’s) at the time. Immigrating to the US in December 1990, Irina co-founded the International Chess Academy in Teaneck, NJ, in 1997 (you can read more about the chess school and Irina's chess career at
