Interesting problem. How about: 1. Rh3 ? with the following lines:
a) 1....g6 2. Rxh7 Kxh7 3.Qh5 Kg7 (if Kg8 then Bxg6 right away) 4.Qh6 Kg8 5.Bxg6 fxg6 6.Qxg6 Kh8 7.Rf1 with the idea Rf3 and h3. I can't see a defence against that plan. If black plays Rg8 for example he will be mated with Qh6#.
b) 1....h6 2.Bxh6 gxh6 3.Qg4 Kh8 4.Rxh6 mate. If Black does not take on h6 White can continue his (or her) attack with Bxg7, Qg4 or Qh5. White's position is so good, it should easily be won.
c) 1...f5 2.Qh5 h6 3.Bxh6 and if gxh6 then 4.Qg6 Kh8 5.Rxh6 mate.

What do you think Jakimaster? ;-)
