Should he? If White can engineer the trade of Black's g-pawn, and get his king
to the h1 corner or near it, it's drawn. Wrong color bishop! (Or wrong color
rook-pawn, call it either way.) Stockfish has it pegged at the highest value
I've seen for this sort of situation: -60.55. (Well, 43.Kd3 gets -60.47.) But
no mate! (depth 42 already done)} 0-1
