First Encounter and the Fischer's Bust
Spassky and Fischer met for the first time in Mar del Plata in 1960 for a much anticipated game. Both players wanted to win badly.
Fischer got crushed by Spassky in the King's Gambit, a favorite line of Spasskys who was nicknamed the "Knight of the King's Gambit." Back then, playing the King's Gambit was still fashionable among grandmasters.
Fischer was so infuriated by the loss, that when he got home he wrote an article entitled "A Bust to the King's Gambit.". This article became the most famous article about an opening ever, and it had devastating affects on the King's Gambit opening.
