72... h2? 72... Rb1 73. Kc7 (73. g7 Rxb6+ 74. Ka7 Rg6) 73... h2 draws 73. g7 h1=Q 74. Rf8+ Ke5 75. g8=Q Qh2 76. Rf7!? It's surprising that Black doesn't go for the simple 76. Qh8+ Qxh8 77. Rxh8 with a theoretical win. 76... Kd4+ 77. Rc7 Rxc7 78. bxc7 Tablebase says mate in 24 here. 78... Kc5 79. Qg5+ Kc6 80. Qg6+ Kd7 81. Qf7+ Kc6 82. Qf3+ Kc5 83. Qc3+ Kb6 84. Qb4+ Kc6 85. Qc3+ Kb6 86.

38... Qf4?? 38... Rh1+ 39. Kxh1 Qh5+ and Black can try to win without any risk. Perhaps Black forgot about the knight on e3 protecting g2. 39. gxf4 1-0
