actually this is a simpler version of a more complicated puzzle
white to play and win
[fen]3K4/kp6/p7/1P6/8/8/7P/8 w - - 0 1 [/fen]
(yes all i did was move the king over one but it makes a big difference)
HINT:the following is the fen notation of the position after 1 move by each side
Made possible by Black's 1st move.
Not 7.Qe8? Qg7!, or 7.Qxa1?, stalemate.
The only way of stopping the discovered check.
8.Qe8 Qa4 9.Qe5+ Ka8 10.Qh8!
Renews the back-rank battery, now that Black's stalemate trick is gone.
