36. Bd2? { Missing a tactic which
complicates the result. In defence of the quality of play here both players
were already below 5 minutes. } (36. Rxg5 Kxg5 37. Bd2 Kf5 38. Rxf6+ Rxf6 39. Bxf4 Kxf4 $16 { was probably good enough for White to win. }) 36... Rxf3+ 37. gxf3 Bxd2 38. Rbb6 Nd7 39. Rxg6+ Kh7 40. Rbd6 Bf4 41. Rxd7 Rxd7 42. Rg4 Rd3+ 43. Kc4 Rxf3 44. Rxh4+ Kg6 45. b4 Rxf2 46. a4 Kg5 47. Rg4+ Kf5 48. a5 Rc2+ 49. Kb5 Rc3 50. Rxf4+?! { This is probably a mistake. Now I was looking for a way
to set up a sacrifice of the rook for the more advanced pawn followed by a
capture of the other by the king, meaning the Black king needs to get in touch
with the b4 pawn, ASAP. Still it's hard to judge, the bishop would have been a
good defensive piece also. } 50... Kxf4 51. a6 Rxh3 52. Kc6 Rh6+ { Side checks force the White king back to the a5 square. } 53. Kb7 Rh7+ 54. Kb6 Rh6+ 55. Ka5 Ke5 56. b5 Kd6 57. a7 Rh1 58. Kb6 (58. b6 Kc5 59. Ka6 Ra1+ 60. Kb7 Kb5 { Also leads to a later game position. }) 58... Ra1 59. Kb7 Kc5 60. b6 Kb5 61. Kc7 Rc1+? { I realised while waiting for a reply that my instinctive
move (which I had seen several moves prior) was a catastrophic error. } (61... Ra6 62. b7 Rxa7 63. Kc8 Rxb7 64. Kxb7) 62. Kb8?! (62. Kd6 { now is just leading to a technically winning queen vs rook endgame. }) 62... Rh1 63. b7 Kb6 { and I guess to both of us this looked very threatening. I know
neither of us realised this is still a trivial win for White. } 64. a8=N+?? { Going from winning to losing. The knight can't escape from the corner and
Black is winning the last pawn. } (64. Ka8 $18 { and that is that. }) 64... Kc6 65. Ka7 Ra1+ 66. Kb8 Rb1 67. Ka7 Rxb7+ 68. Ka6 Rb1 69. Ka7 Rb2 { 0-1 White resigns. } 0-1
