What about 1...h5 2.Nf6 Bg7 3.Qg4!?
E.g.: 3...Bxf6 4.Rxh5!! Kg8 (4...Kg7 is #7; 4...gxh5 5.Qxh5 also #7) 5.gxf6
cxb2+ 6.Kb1 +-. It is hardly possible to find a defense against 6.Rh8+ Kxh8
7.Qh4+ and soon mate. 5...Qb6 does not save: 6.b3 and still the threat on h8/g7
decides.
The only way seems to be 3...Qb6, e.g. 4.bxc3 Bg7 5.Qxh5+ gxh5 6.Rxh5+ Bh6
7.Rxh6+ Kg7 8.Rh7+ Kf8 9.Bxc5 Qxc5 10.Nd7+ and now draw by 10...Kg8 11.Nf6+ or
unjustified try to play for a win with 10...Ke7 11.Nxc5. But wait, 5.Qg4 in this
variation also seems to be quiet strong with similar variations as above.

So finally I do not see any defense for the plan Qg4 and Rxh5. Do you?
