    1.Rg8 Qa2 2.Rf8 Qa3 3.Ke8! looks like a promising start...

    That's actually it. Black can't do a thing. The only way for him to prevent mate is to play 3. ... Qe6 4. Kf7 Qb7 5. Rxb7 and white king can just move in to lock up the black king while with no hurry queen his pawn and mate black.

    Looks like you mean 3...Qd6 4.Kf7+ Qb8 5.Rxb8+.

    I had refrained from solving this because I thought it was going to have essentially the same solution as another oft-posted problem on these forums:


    White wins

    1.h4 a5 2.h5 a4 3.h6 a3 4.h7 a2 5.h8Q a1Q! 6.Qg8! [not 6.Qxa1??, stalemate] 6...Qa2 7.Qe8 Qa4 8.Qe5+ Ka8 9.Qh8! 1-0

    Yes, I did mean Qd6. Just the letters 'e' and 'd' are very near on the keyboard. And I have no idea did I write Qb7. I was in a hurry so I had a few typos. Stupid ones, indeed, but good that you understood and there weren't any misunderstandings. (I hope there weren't)

    Brilliant if my solution is right.
    1. Bg6+! Kxe5
    2. d4+! Kxd5
    3. e4#
    or;
