Bondarevsky played 51...Nxf5. Does White have any chance of drawing if 51...Rxd2? I think so. For example:

52.Rxd2 Nf3+ 53.Kg2 Nxd2 54.Kxg3 Ke7 55.a4 Nb3:

Or, in this position:

What if Black tries to send the king to the queenside, keeping the N watching the f-pawn and pushing the d-pawn? I can't make it work. For example:

58...Ke7 59.Kg5 Kd7 60.f6 Kc6 61.f7

61...Kb5 62.Kf5 Nd7 63.Ke6=

Dec-20-10  hms123: <Fusilli> Also, your <55.a4??> is a lemon. White should play <55.Kf4> with a draw.

Also, <54...Ke7?> should be either <....Nc4, ...Ne4+, or ...d5>

May-13-15  zydeco: You don't see Geller lose too many games a pawn ahead in the endgame (as he is after move 33).

The plan with 45.g4 and 46.Rd4 turns out to be a bad misfire.

Obviously I don't know how far ahead Bondarevsky saw. But it would be pretty impressive if he saw that, by giving up the a-pawn on move 33, he could surround white's d-pawn, and then white would have a tough time stopping black's central pawns.
