Svetozar Gligorić (Serbian Cyrillic: Светозар Глигорић) (February 2, 1923 - Aug 14 2012) was a Serbian chess grandmaster. He won the championship ofYugoslavia a record twelve times, and is considered the best player ever from Serbia. In 1958 he was declared for the best athlete of Yugoslavia.
During the 1950s and 1960s, he was one of the top ten players in the world, also among the world's most popular, owing to his globe-trotting tournament schedule and a particularly engaging personality that is reflected in the title of his autobiography, I Play Against Pieces (i.e., with no hostility to the opponent, or playing differently for "psychological" reasons against different players; playing the board not the man).
Gligorić was dangerous to the world chess champions, though he had minus scores against most: Mikhail Botvinnik +2 −2 =5, Vasily Smyslov +5 −7 =21, Tigran Petrosian +7 −10 =10, Mikhail Tal +2 −11 =19, Boris Spassky −5 =15, Bobby Fischer +4 −6 =6, Anatoly Karpov −4 =6 and Garry Kasparov −3.
