Неправильный результат

- вот ссылка на партию, у соперника упал флаг и присудили ничью, хотя мат возможен. Как добиться правильного результата?

After move 58 from white (which is bizarre), this game is total nonsense. Utter nonsense.

Yeah, seems to be a bug.

@cp560 there were only a few seconds on the clock, that is when quality doesn't matter anymore.

@bufferunderrun and @Gulik86
Please share how white can win the final position of post #1. From the final position, please post a legal sequence of moves that leads to win by white.

Here you go:
[FEN "4K3/4b2B/8/8/4r3/2k5/8/8 b - - 9 70"]

70... Re1 71. Kd7 Bh4 72. Bf5 Kb4 73. Bh3 Kb5 74. Bg4
Ka6 75. Bh3 Ka7 76. Bg4 Ka8 77. Bh3 Bg3 78. Bg4
Bb8 79. Bh3 Ra1 80. Kc6 Ra3 81. Bg2 Ra7 82. Kb6+
Rb7+ 83. Bxb7#

#6
This should be a sufficient proof that @Gulik86 #1 deserves the win. Thank you for the help!
