32 ..gxf5 33 Rxf5+ Ke8 and Black is still well in the game.
33 g5
This wins material, but White had an even stronger continuation here. My guess is that both players were in time trouble. 33 fxg6+! Kxg6 34 Rf5! is a killer as Black has no good defence to 35 Nf4+.
33 ..gxf5 34 Kh3 a5 35 Kxh4 a4 36 bxa4 Ra8 37 a3
37 Rxf5+ Ke7 38 Kh5 Rxa4 39 g6 hxg6+ 40 Kxg6 is easily winning for White, but would be difficult to spot in time trouble.
] 37 ..Rxa4 38 axb4 Rxb4 39 Kh5?
39 Rxf5+ Ke7 40 Rf4 c2 41 Be3 Rb3 42 Bc1 Rb1 43 Rf1 and White should win. Now it's really unclear.
39 ..c2 40 Rc1 Rb1 41 Be3
41 Rxc2? Rh1+ and mate next move.
41 ..Na5 42 Nd4 Nb3! 43 Nxb3 Rxb3
Suddenly White is in a big tangle as his king is caught on the edge.
44 Bf2 Rc3 45 Kh4
Or 45 Be1 Rh3+ 46 Bh4 Rh2 and now Black's plan is to rush his king over to the queenside. 47 Re1 Kf8 48 g6 (what else?) 48 ..hxg6+ 49 Kg5 Kf7 and Black is better.
45 ..Kg6 46 Ba7 Rc4+ 47 Kh3 Kxg5 48 Bb8 Kf4 49 Bxd6+ Ke4 50 Bf8 Kxd5 51 Bh6 Rc3+ 52 Kh4 Rc4+ 53 Kg5 Ke6 54 Bg7 Rg4+ 55 Kh6 Rg2 56 Kxh7 f4 57 Re1+ Kd5 58 Bh6 f3 59 Re8 f2 60 Rd8+ Ke6 61 Re8+ Kd7 62 Rf8 Rh2 0-1
Amazing!
