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.
