Answers.Text: The back rank is "mined": 1 . . . Kh8? 2 d8Q *check* and Black has no time for Nf7+.  That's also why most of Black's second-move alternatives are weaker (and 2 . . . Kf7? would directly block the Nf7+ fork). [This was an answer to a "why not 1 . . . Kh8?" comment that I see has been deleted while I was answering . . .]

Body: <p>This time I bring you a beautiful composition. White is down material but is about to queen the d7 pawn. The only problem is the knight fork on f7 and if he doesn't act very quickly Black is going to put his bishop on a5. <strong>How does White win the game?</strong></p>
