Fischer then played first board for the US Team in the 19th Chess Olympiad in Siegen, where he won an individual Silver medal, scoring 10/13 (+8−1=4), with his only loss being to World Champion Boris Spassky. Right after the Olympiad, Fischer defeated Ulf Andersson in an exhibition game for the Swedish newspaper "Expressen". Fischer had taken his game to a new level. Fischer won the Interzonal (held in Palma de Mallorca in November and December 1970) with 18½/23 (+15−1=7), far ahead
Bobby Fischer forfeited the entire match, but Spassky, not wanting to win by default, yielded to Fischer's demands to move the next game to a back room, away from the cameras whose presence had upset Fischer. After that game, the match was moved back to the stage and proceeded without further serious incident. Fischer won seven of the next 19 games, losing only one and drawing eleven, to win the match 12½–8½ and become the 11th World Chess Champion. The Cold War trappings made the match a media sensation. It was called "The Match of the Century", and received front-page media coverage
