Further madness

The yearly speed championship started yesterday evening in my local chessclub - each player is alloted 25 minutes of time with a 10 seconds move increment. Ideal for a Blackmar Diemer. But unfortunately, my first opponent refrained from playing d5, so I had to revert to some other madness.

1.d4 Nf6 2.f3 g6
What player is so unreasonable as to refuse to enter the Blackmar Diemer ? He should be punished immediately with ...

3.g4
That got him thinking !

3...Bg7 4.h4 (diagram)
You cant say I am not consistent in my moves :-)

4...d6 5.h5 gxh5 6.g5

6...Nfd7
The other option is 6...Nd5 7.e4 Nb6 8.Ne2, which is probably better for white.

7.e4
Here my opponent choose the inferior 7...e5 and I could easily get the advantage with 8.d5.

The obvious critical line is 7...c5 and we reach the standard Paleface setup after 8.d5 (diagram)

My silicon assistant gives following line as best : 8...h6 9.gxh6 Bxh6 10.Bxh6 Rxh6 11.Qd2 with a slight advantage for white.

I cant find any games on this line in nay database, but the moves 1.d4 Nf6 2.f3 g6 3.g4 certainly seem playable. Please let me know if you had any experience with this.
