Dr. Steinbacher in BDG Declined

FIDE Master Matthias Steinbacher backed into a Blackmar-Diemer Gambit Declined in the 3.Nc3 c5 line. After 4.d5 the game transposed to an Albin-Counter Gambit Reversed. The move order 1.Nc3 d5 2.d4 c5 3.e4 reaches Sicilian Defence if the moves are played in reverse order: 1.e4 c5 2.d4 d5 3.Nc3. This would be a Smith-Morra Gambit Avoided. I covered this line in my Sicilian Defence book in the section 2.d4 d5.

Dr. Steinbacher is an experienced player from Germany who was born in 1951 according to FIDE. Playing Black was Malte Colpe rated 2394. He was born in 1992.

The position after the first four moves mirrors the Albin Counter after 1.d4 d5 2.c4 e5 3.dxe5 d4 4.Nf3 Nc6. There in the Albin, the gambit player is Black and it is not his move. In Steinbacher vs Colpe, the gambit player is White and it is his move. The BDG becomes an Albin with an extra move.

I analyzed possibilities starting with move five. White had good alternatives on moves 5, 6, and 9. White was outplayed by a higher rated player. Congratulations to Malte Colpe!

The line 3.Nc3 c5 is section 1.2 in my Blackmar-Diemer Games 2 book.
