Hi Richard and all, After looking at this problem I discovered that white can mate black in two moves. I don't know if this is the move that your answer says, but this is what I would do: 1. Qxh7+ Kxh7 2. hxg6++ With the pawn on g6 being backed up by the bishop on d3, and the rook on h2, you definitely have checkmate. Since the king is in check by two sources, there is nothing black can do to defend the move. I must admit my first thought was to move the white queen to g5 threatening the black queen, therefore swapping queens and putting whites knight on g5. I also think this would give white more of an advantage in the game, but there is not more of an advantage than checkmate, smiles!
