The main point is that if white is left with just the h-pawn and the bishop he cannot win. Even with two h-pawns it is drawn. This is because white's bishop does not control h8. If his bishop was on a dark square he would be able to win easily with the h-pawn. So white needs to keep the g-pawn. His easiest winning method is to force the black king from h4 and then from g5 and then move his own pawn to g5. Then it is easy.} 56. Be2 {There are lots of ways of winning. What follows is just one example. White starts by simply simply waiting, until black cannot advance his e-pawn and has to move his king backwards.} (56. gxh5 {Now it is drawn. Let's see why.} Kg5 57.
