About Svetozar Gligorić
Svetozar Gligorić (Serbian Cyrillic: Светозар Глигорић; 2 February 1923 – 14 August 2012) was a Serbian chess grandmaster and musician. He won a record 11 titles at Yugoslav Chess Championship, a record 12 team medals at Chess Olympiad, and is considered the best player ever from Serbia and Yugoslavia. In 1958, he received the Golden Badge award for the best athlete of Yugoslavia. During the 1950s and 1960s, Gligorić was one of the top players in the world reaching the Candidates Tournament three times (1953, 1959, 1968). In his career he won both team (1950) and individual board 1 (1958) gold medals at the Chess Olympiad thus becoming one of the few players in chess history to do so (along with Kashdan, Rubinstein, Botvinnik, Petrosian, Spassky, Karpov, Korchnoi, Kasparov, Ivanchuk, Aronian, Ding and Gukesh). He was also among the world's most popular players, owing to his globe-trotting tournament schedule and a particularly engaging personality, reflected in the title of his autobiography book, I Play Against Pieces (i.e., without hostility toward the opponent; playing "the board and not the man"). He won the championship of Yugoslavia a record 11 times, and is considered the best player ever from Serbia and Yugoslavia. His first tournament success came in 1938 when he won the Belgrade Chess Club championship; however, World War II interrupted his chess progress for a time. He continued to progress as a player and in the year of introduction of FIDE titles (1950) he was awarded the International Master title.
