On Feb. 21, Kiril Georgiev of Bulgaria played 360 people simultaneously in Sofia, Bulgaria, breaking the world record for such a feat. His final score was 284 wins, 70 draws and 6 losses. The previous record holder, Andrew Martin, an English international master, had played 321 opponents at Wellington College in Berkshire, England, on Feb. 21, 2004. Susan Polgar of the United States played 326 people simultaneously at a mall in Palm Beach Gardens, Fla., in August 2005, but the Guinness Book of World Records did not recognize her record as official.

It took Georgiev more than 14 hours to set his record.
