The opening game occurring on this day in 1972, the
World Chess Championship pitted US challenger

Bobby Fischer against defending champion Boris Spassky of the USSR (
see previously), the former after twenty-one matches played over the course of five weeks ending a twenty-four year Soviet monopoly on the title. The tournament was hosted in Reykjavík, and Fischer didn’t score a win until round three, most ending in a draw (the scoring convention was a bit skewed and encouraged whomever was in the lead to play for ties rather than an outright conquest)—though at 12½ to 8½, Fischer could be proclaimed as the undisputed overall victor under those rules.
