Bobby Fischer's openings in the 1972 World Chess Championship are said to have taken Spassky completely by surprise:
Fischer played always e4 as his opening move, in football terms he had a very limited playbook, he always played the same opening moves, and (in 1972 WCC) he defied the Russians (and the world) to beat him. From the age of 12 - 29, he played exactly the same opening moves.
In the 1972 World Chess Championship, how many new openings did Fischer use against Spassky, and across how many games did he use them?
