Mr Herman lets assume that the pawn structure is the same black Ke7 and Bf5.Whites Kc5 and Ne3 .White to move win by Nxf5 if exf5 kxd5 and the pass pawn will queen and if gxf5 g6 [a(if hxg6 h7) [b(if kf8 gxh7 queen) I played over this game several times and the Bishop can't stop the Night from getting to f6.On move 46 instead of Bc4 black had to play Bxe2 put his king on d7 and move his rook back and forth on the seventh and eighth ranks and the game is a draw.I hope one of these years(soon) that chess programs will give the correct positional value,evaluation and assessment of these kinds of positions
