Walk on the Wild Side
This game features yet another ridiculously bold king march. Petrosian decides to keep his king in the center and spurns castling when it becomes clear that Cardoso is mounting an attack. He then snatches at the opportunity to win some material, counting on his ability to defend. In the end, his king has to go on a little walk, almost to its doom, but with some imaginative and creative play, Petrosian manages to escape unscathed, and Cardoso is forced to capitulate when his own king comes under fire.
