The fix is in

Would you offer a draw if you were Black in the final position of the following game? Petrosian did, not caring that he seems to be close to winning in this position (at least according to Fischer in Sports Illustrated ). However if you feed the position into your favourite chess engine it does not seem to give Black that much of an advantage, even looking 10 moves (20 ply) ahead. Of course what is a small edge for the computer may be a decisive one for a world class GM, but given that Petrosian went on to win the tournament, maybe he just wanted the day off.
