The World Chess Championship 1972 was a match between challenger Bobby Fischer of the United States and defending champion Boris Spassky of the Soviet Union for the World Chess Championship. The match took place in the Laugardalshöll arena in Reykjavík, Iceland and has been dubbed the Match of the Century. Fischer became the first American to be the official World Champion since Steinitz, the first Champion, became a naturalized American citizen in 1888. Fischer's win also ended 24 years of Soviet domination of the World Championship. The first game started on July 11, 1972. The last game began on August 31 and was adjourned after 40 moves. Spassky resigned the next day without resuming play. Fischer won the match 12½-8½, becoming the eleventh official World Champion.
