More Mad Dog

We all know we don't see the Blackmar-Diemer played that much in "serious" chess, so I was a bit surprised to come across this game played a decade ago in the second round of a tournament in England. Does the audacity (a popular word these days) of this variation account for Black's tenth move? Black is not a weak player. Now he is a FIDE master with a rating of 2327. But then he reacted badly in his encounter with a mad dog. Ormrod,Joe P - Webb,Laurence (2225) Aintree Open (2), 05.06.1998 BDG, Bogoljubov Defense, Mad Dog Variation [D00] 1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 g6 6.Bc4 Bg7 7.h4 c5
8.h5 gxh5 9.Ne5 e6 10.Bg5
Inexplicable. Clearly better was 10...Qxd4 11.Qe2 Nd5 12.Nxd5 Qxe5 13.Qxe5 Bxe5 14.Nf6+ Bxf6 15.Bxf6 Rg8 16.Rxh5 a6 (16...Rxg2 17.Rxh7 Rg1+ 18.Bf1+/=) 17.Rxh7 Nd7 =/+
11.Nxc6+- bxc6 12.Qf3
12...Qxd4 gets complicated quickly, e.g., 13.Qxc6+ Nd7 14.Qxa8 Qe5+ 15.Be2 Qxg5 16.Qxc8+ Ke7 17.Qc6 Qg3+ 18.Kf1+-
13.0-0-0 Rb8 14.Bb3 c5?
Not good, but I can't find a move here to prevent the loss of a piece.
15.Ne4 Bb7 16.Nxf6+ Bxf6 17.Qxf6 Qxf6 18.Bxf6 Rg8 19.Ba4+ Kf8
Okay, but 20.Rxh5 is better 20...Bd5 (20...Bxg2 21.Rxc5) 21.Rxh7 Rb4+- with 22.Rdh1!? or 22.b3.
20...Rc8 21.Bd6+ Kg7 22.Rxh5 Be4 23.Bxc5 Kg6 24.Rdh1 Bxg2 25.Rh6+ Kf5 26.R1h5+ Ke4
26...Rg5 27.Be7 Rxh5 28.Rxh5+ Kf4 29.Rxh7+-
27.Rh4+ Kd5 28.Bxd4 Be4 29.c3+-
27...e5 28.Bd3+ Kd5 29.b4
29...Rg6 30.Rxh7 Rf6 31.Rg5 and Rhh5+-
30.Rd6# 1-0
