BDG Lemberger Counter Attack

The Lemberger Counter Attack is a promising choice if Black does not want to accept the Blackmar-Diemer Gambit. After 1.d4 d5 2.e4 dxe4 3.Nc3, instead of the normal BDG 3…Nf6 4.f3, Black offers an e-pawn with 3…e5. My favorite continuation is 4.Nge2. I've written about this variation in several of my books. Here are some other recent choices.

1.d4 d5 2.e4 dxe4 3.Nc3 e5
The main line in this post is 4.Qh5. First, let's consider alternatives.
