I saw this game tonight and thought it deserved its own thread. The final position is fairly normal. Black wins with white's king trapped in the center of the board and his own king is on g8. If you just saw the final position, you'd probably think it was just another Sicilian with black coming out on top. But watch how black's king gets to g8. Petrosian is an unbelievably imaginative player.
