70... Ra4 was much simpler.

71. Kf2 Nd3+??

Chess blindness? After almost anything else, Black is still winning, e.g. 71... Re2+ 72. Kg1 (72. Kg3 g1=Q+ 73. Bxg1 Rg2+) 72... Re1+ 73. Kh2 Rh1+ 74. Kg3 g1=Q+, etc.

72. Kg3??

Mutual chess blindness. 72. Kxf3=.

72... Ne1 73. Rf8+ Kg6 74. Bf2 Kg7 75. Rf5 Re6 76. Ra5 Rg6+ 77. Kh2 Rh6+ 78. Kg3 Rh1 79. Ra7+ Kf6 80. Ra6+ Ke5 81. Ra5+ Ke4 82. Ra4+?

White needs to keep the king out; 82. Ra3 holds.

82... Kd3 83. Ra3+

83. Ra2, to keep the king out, now fails to 83... g1=Q+ 84. Bxg1 Rxg1+ 85. Kf4 Rg2.

83... Kd2 84. Ra2+ Kc3?

84... Kd1! wins, e.g. 85. Kf4 (85. Ra1+ Ke2 86. Ra2+ Kf1) (85. Ba7 g1=Q+ 86. Bxg1 Rxg1+ 87. Kf4 f2) 85... g1=Q 86. Bxg1 Rxg1 87. Ke3 and while there is still work to do, it's a tablebase win.

85. Ra3+ Kb2 86. Re3 g1=Q+ 87. Bxg1 Rxg1+ 88. Kf2 Rh1 89. Rxe1 Rxe1 90. Kxe1

1/2-1/2
