King's Gambit, Fischer Defense King's Gambit, Fischer Defense The Fischer Defense to the King's Gambit is a chess opening variation that begins with the moves: Although 3...d6 was previously known, it did not become a major variation until Fischer advocated it in a famous 1961 article in the first issue of the "American Chess Quarterly". In the "Encyclopaedia of Chess Openings", the Fischer Defense is given the code C34. After Bobby Fischer lost a 1960 game at Mar del Plata to Boris Spassky, in which Spassky played the Kieseritzky Gambit, Fischer left in tears and promptly went to work at devising a new defense
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
