If the b-pawn is removed, White cannot win even if black lost all his material since the bishop is the wrong color and does not control the h8-square.} Nb4 68.

Mekhitarian was clearly upset at the board, and playing more to calm his nerves than anything. Fier was playing all his moves almost instantly.} 85. Kc5 Ne6+ 86. Kd5 Ng7 $1 87. Kc4 Kb6 88.
