X34 18.gxf5 X35 Bxf5 X36 19.Kh1 X37 Qxh3 X38 20.e4?! X39 Be6 X40 21.Rg1 X41 Bh6 X42 22.Bc1 X43 Bf4 X44 23.f3 X45 Kg7 X46 24.Bxf4 X47 exf4 X48 25.a3?

An excellent ending for Black: Bishop v Knight and fixed pawn weaknesses f3 and d3 to exploit.

30...Rh5 X60 31.b5? X61

White plays a move that improves the Black pawn-structure and the scope of the Bishop!

31...cxb5 X62 32.cxb5 X63 Kf6 X64

Another plus for Black: a rapidly centralised King.

33.a4 X65 Rd4 X66 34.Rc2 X67 Rh8 X68 35.Kg2 X69 Rhd8 X70 36.Kf1 X71 Rb4 X72 37.Ra3 X73 Rdd4 X74 38.Re2 X75 Rb3 X76

[ 38...Bb3 X77 would have won the a-pawn. One suspects time-trouble influencing the game.]

39.Ra1 X78 Rdb4 X79 40.Ra2 X80 Rc3 X81

[ 40...c4! X82 41.dxc4 X83 ( 41.Nxc4 X84 Rxd3-+ X85 ) 41...Rxf3+ X86 42.Kg2 X87 Rc3 X88 was stronger.]

41.Ra1 X89 Rcb3 X90 42.Ra2 X91 c4 X92

With the time-control passed Black finds the key move.

43.dxc4 X93

[ 43.Nxc4 X94 Rxd3-+ X95 ]

43...Rxf3+ X96 44.Rf2 X97 Rxf2+ X98

[ 44...Re3 X99 was also correct, but Black knows the e-pawn will fall later.]

45.Kxf2 X100 Bxc4 X101 46.Nxc4 X102 Rxc4 X103

The Rook ending is won for Black.

47.Kf3 X104 Ke5 X105 48.a5 X106 Rc3+ X107 49.Kg4 X108 Kxe4 X109 50.axb6 X110 axb6 X111 51.Ra4+ X112 Ke5 X113 52.Rxf4 X114 f5+ X115 53.Kg5 X116 Rc2 X117 54.Rf1 X118 Rg2+ X119 55.Kh6 X120 Kf6 X121

[ 55...Kf6 X122 56.h4 X123 Rh2 X124 57.Kh7 X125 Rxh4+ X126 58.Kg8 X127 f4 needs no commentary.] 0-1
