Improve Your Chess: Highly Instructive Games - Spassky-Fischer Game 3, 1972

Fischer, down 0-2, causes a sensation with his "anti-positional" offer ..Nf6-Nh5. Spassky correctly accepts the challenge but misplays slightly and grants Fischer first equality and then the better position. As happens so often, the GM under pressure eventually makes some second-best moves and drifts from a difficult position to lost. Once Fischer gets the winning position, his technique, not surprisingly, is excellent, and he brings home the entire point. That makes this game not only instructive, but historically important as Fischer amazingly turned the 2-0 deficit into a 6.5-3.5 lead after 10 games en route to his title.
