The “Match of the Century” between World Champion Boris Spassky [pictured] and his challenger Bobby Fischer was due to start in the first days of July 1972 in Reykjavik, Iceland. Spassky, who had the backing of the mighty Soviet chess machine behind him (the title of World Chess Champion had been held by USSR citizens for twenty-four years), had arrived in the Icelandic capital well on time. But his opponent, the maverick US grandmaster Fischer, who was working essentially all on his own, sat in New York, unsatisfied with the conditions.
The Championship was to be a 24-game match in which the reigning champion had draw odds: if the match ended in a 12-12 tie, the title would remain with Spassky. Fischer’s Elo rating was 2785, 125 points higher than Spassky’s (2660). The prize fund was $125,000 – 5/8ths to the winner, 3/8ths to the loser.
After two traumatic games for Fischer at the outset, World Champion Spassky was leading 2-0 in the match. But then Fischer started to play and struck back: in the next eight games he scored 6½ points, chalking up a 6½-3½ lead. Games 8, 9 and 10 were quite spectacular.
Most chess enthusiasts know the outcome of the confrontation. In the end, Fischer became world champion after beating his Soviet rival by a 12½-8½ score.
