Dispair in the GiveAway variation

hello Blackmar Diemer fans,

Yesterday evening I played a few blitz games in my local chess club, several of them were based on the Ziegler/O'Kelly defense

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 c6 6.Bc4 Bf5 when I venture the surprising 7.g4 !!
Because of obvious reasons, I called this the GiveAway variation.

Black should of course accept the gift and capture 7...Nxg4, but yesterday evening, most of my opponents choose to play it carefully with 7...Bg6

What can now complicate things again with yet another sacrifice 8.h4!!  Nxg4 9.Ng5 (diagram)

Black has two moves 9...h5 and 9...Nh6

After the seemingly robust 9...Nh6, white gets great attacking chances with 10.Qe2 (diagram)
A. 10...Qxd4 11.Be3 Qg4 12.Qxg4 Nxg4 13.h5 (=)
B. 10...Qc7 11.Be3 (=)
C. 10...e6 11.d5 (=)
D. 10...b5 11.Bb3 (=)
E. 10...Nd7 11.Bf4 (=)

So the robust 9...Nh6 does not offer any advantages, let's look at the more aggressive 9...h5 10.Bf4 (diagram)
White is risking all here and black can remian on top in various ways
F. 10...b5 11.Bb3 e6 12.Qe2 Bb4 13.Bxe6 (=+)
G. 10...e6 11.Qe2 Bb4 12.0-0-0 0-0 13.Bd3 (=+)
H. 10...Nd7 11.Qe2 Nb6 12.Bb3 (=+)

So it seems the ultra aggressive 8.h4 is not so good if black decline sthe pawn in the GiveAway variation. The problem is that 8.g5 might not offer better prospects 😓 aftre 8.g5 Nd5 (diagram)
