Refused, but not refuted

A few weeks ago, I played an opponent who was well aware of my Blackmar Diemer knowledge – well in fact, I slaughtered him two years ago when he selected the Euwe defense – he got mated in the standard attack.

This time, he wisely decided to refuse the pawn that was offered to him.

Guido De Bouver - Tom De Bue

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 e3 5.Bxe3 Bf5 (diagram)

The Langeheinicke defense. No advantage can be expected for the defender.

I now choose the inferior 6.Bd3 and the game quickly ended in a draw.

But what about the immediate 6.g4 Bg6 7.Nge2 (diagram)

a/ 7...e6 8.h4

...a1/ 8...h5 9.Nf4 (+=)

...a2/ 8...h6 9.Nf4 (+=)

b/ 7...Nd5 8.Nxd5 Qxd5 9.Nf4 (+=)

c/ 7...h6 8.h4 (+=)

d/ 7...h5 8.Nf4 (+)

e/ 7...c6 8.h4 (+=)

f/ 7...Nbd7 8.h4 (+=)

g/ 7...Nc6 8.Nf4 (diagram)

...g1/ 8...Nb4 9.Nxg6 hxg6 10.Qd2 (=)

...g2/ 8...e6 9.h4 (+=)

...g3/ 8...e5 9.dxe5 (+=)

So it is clear that the Langeheinicke defense wont bring any advantage to the defender - but we all knew that, didn't we ?
