Fischer–Spassky (1992 match)
The 1992 match between former World Chess Champions Bobby Fischer and Boris Spassky was billed as a World Chess Championship, but was unofficial. It was a rematch of the 1972 World Championship match. The match started in Sveti Stefan near Budva, an island off the coast of Montenegro. The match rules required a player to win ten games (draws not counting), with no adjournments. After a player had won five games, the match would take a 10-day recess and continue in Belgrade, the capital of Serbia. Both places were at the time part of the same country, the Federal Republic of Yugoslavia which was under heavy UN economic sanctions because of the country′s involvement in the war in Croatia and Bosnia.
Fischer won the match 10–5.
