Blackmar-Diemer Gambit 5.Nxf3

This month I have a collection of recent Blackmar-Diemer Gambit Accepted games. As usual, I try to publish on the 7th of the month. The BDG remains a tricky opening that works well in blitz when White is prepared with some opening knowledge tactical skills, and an eager search for targets of opportunity.

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3

5...c6 6.Bc4 Bf5 7.0–0 e6 8.Ng5 Bg6
9.Bxe6!? (White sacrifices a piece for two pawns. 9.Ne2 intending 10.Nf4 is a more cautious approach.) 9...fxe6 (Or 9...h6) 10.Nxe6 Qd7 11. Kf7 (Maybe 11...Qxe6 12.Bxf6 gxf6 13.Re1 regains the material) 12.d5! cxd5 13.Nxd5 (The critical line is 13.Bxf6 Qxe6 14.Bxg7+ Kxg7 15.Qd4+ Kh6=) 13...Qxe6 (13...Kxe6 favors Black, but it sure looks risky in blitz.) 14.Nxf6 Bc5+ 15.Kh1 gxf6 16.Rxf6+ Qxf6 17.Qd5+ Qe6 18.Rf1+ Bf5 19.Rxf5+ 1–0 Arslanov - Li, chess.com 2024
