In the diagram to the left, black is clearly better because of his connected passed pawns. However, his pawn on the h-file must fall, and how to play the arising ending is not as straightforward as it may seem at first.
After 1.Be7 Nd3, it would appear that white’s best is to take the pawn immediately with 2.Bxh4. However, this capture is slightly inferior, since the pawn can be captured at will later on. A stronger defense, though admittedly still losing, is 2.Nd6, when black’s pawns a feeling some pressure.
