SOFIA (AFP) — Bulgarian grandmaster Kiril Georgiev on Saturday began 360 chess games in an attempt to break the world record for the largest number of simultaneous games played. "Georgiev began playing 360 games Saturday morning," Bulgarian chess federation chief Stefan Sergiev told AFP. The grandmaster was making an average of three moves an hour, while moving among the long rows of chess tables occupied by opponents who ranged from children to pensioners. Georgiev has to win 80 percent of the games in order to break the previous record set by Hungarian-American chess champion Susan Polgar in 2005. Polgar played 326 games, winning 309 of them, drawing 14 and losing only three.
