These days every chess player has his favorite refutation of the Blackmar-Diemer, but still some consider it the better part of discretion simply to avoid it. One way to do that is via the Hübsch Gambit: 1.d4 Nf6 2.Nc3 d5 3.e4, and now rather than 3…dxe4, satisfying White’s desires, Black plays 3…Nxe4.
It’s not easy to make progress against this, even though GM Tartakower lost with black in the stammpartie of this line (see below). The other day I came across a video that does a good job of presenting some key lines in this variation from black's viewpoint.
You can take a look at this video here: JoshSpecht - Opening Analysis: Hubsch def. vs. BDG [14:36].
And here’s the Tartakower game. I hate to see my favorite grandmaster lose.
