    actually this is a simpler version of a more complicated puzzle
    white to play and win


    (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
    1k1K4/1p6/pP6/8/8/8/7P/8

    1.b6+ Kb8! 2.h4 a5 3.h5 a4 4.h6 a3 5.h7 a2 6.h8Q a1Q
    Made possible by Black's 1st move.
    7.Qg8!
    Not 7.Qe8? Qg7!, or 7.Qxa1?, stalemate.
    7...Qa2
    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.
    1-0

    this is indeed correct but can you provide an explanation for your moves, and a continuation after 10...Qf4

    I've already explained the moves.

    10...Qf4 is refuted by 11.Qa1+.
