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.

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
10...Nc6?
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...cxd4
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
20.Be5
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.Bb5
27.Rh4+ Kd5 28.Bxd4 Be4 29.c3+-
27...e5 28.Bd3+ Kd5 29.b4
29...a5??
29...Rg6 30.Rxh7 Rf6 31.Rg5 and Rhh5+-
30.Rd6# 1-0
