Center Counter to BDG -- Part 3

Here's our final example of the transposition from a Center Counter to the Blackmar-Diemer, again played by now international master Bela Molnar. It's another Euwe Defense, with the thematic challenge of White's d-pawn with c7-c5.

The identical position occurred in a well-known Diemer game, but with Black a tempo behind because he had twice moved his Bishop--from f8 to e7 and then capturing the pawn on c5. That game went  9.Qe2 Be7 10.0-0-0 Nd5 11.Bb5+ Bd7 12.Rxd5 exd5 13.Nxd5 f6 14.Nxf6+ gxf6 15.Bxf6 Bxb5 16.Qxb5+ Kf7 17.Qh5+ Kxf6 18.Qh6+ Kf7 19.Ne5+ Kg8 20.Qe6+ Kg7 21.Qf7+ Kh6 22.Ng4+ Kg5 23.h4+ 1-0 Diemer - Terzi, Rastatt 1953.

Center Counter to BDG -- Part 2

More Molnar, more Center Counter transposing to the Blackmar-Diemer, this time to the Euwe Defense (5...e6).

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.
