Center Counter to BDG

One of the simplest transpositions to the Blackmar-Diemer comes when Black answers 1.e4 with 1...d5, the Center Counter or Scandinavian Defense. White plays 2.d4, opening the possibility of a BDG continuation, as in this game, which ends abruptly with a Queen sac. (Notice how Queen sacs have a tendency to do that.)

White is a Hungarian IM with a 2361 rating in the current FIDE list.

The Queen had to watch f6. 22...Qa6 was probably the best move available, but White maintains the advantage. The Knight trip from c3 to e4 to f6 proves decisive in many BDG games.
