Steve Stoyko had this position in a game against Tigran Petrosian in a simultaneous exhibition. All of the other games had concluded in victories for the former champion, and so he was seated in a chair across from Steve for the remainder of their game. Steve sacrificed his pawns to reach this ending, which he recognized to be a draw, though it is not one you are likely to find in a book. He was rather surprised when Petrosian insisted on playing it out, and after several attempts at winning, the former champ gave up and knocked over the pieces in disgust. Steve, who had always been a great admirer of Petrosian’s up to that point, was disappointed, not only in his behavior but in his both failing to win the game and also failing to recognize the draw. According to Scott Massey, who was at the event, Steve said “Petrosian’s a fraud.” The ending, though, is not — though your computer will still think it is a win in the final position.
