Blackmar-Diemer Huebsch Gambit

The Huebsch Gambit falls under the Blackmar-Diemer Gambit (BDG) chess openings. The Huebsch Gambit arises after the moves 1.d4 Nf6 2.Nc3 d5 3.e4 Nxe4. The gambit is named after E. Huebsch who won as White vs Tartakower in 1922. As in the BDG proper (3...dxe4 4.f3), this 3...Nxe4 aims to rapidly develop the pieces and open lines for the attack at the cost of a pawn. The Huebsch Gambit trades off Black's kingside knight.
The normal continuation 4.Nxe4 dxe4 seeks to exploit the central pawn structure imbalance. White's idea behind this pawn sacrifice is to gain a lead in development and open lines for attacking the Black king. The gambit leads to unbalanced positions that can offer white good chances for an initiative, especially in club play or among players unfamiliar with the intricacies of the gambit. The critical evaluation of the Huebsch Gambit, like many gambits, depends on the player's style and preparation.

After the moves 1.d4 Nf6 2.Nc3 d5 3.e4 Nxe4 4.Nxe4 dxe4, White has several options for the fifth move, each leading to different types of positions and strategies:
1.d4 Nf6 2.Nc3 d5 3.e4 Nxe4 4.Nxe4 dxe4:
The main line for this post is 5.Be3, but first let's consider two other options:

5.f3: With this move, white aims to undermine the e4 pawn and reclaim it, restoring material equality while opening lines for the bishop and queen. This move signals white's intention to play for a strong center and develop the pieces rapidly. Although it weakens the kingside somewhat, the idea is to leverage the lead in development and central presence to launch an attack or exert pressure across the board.
5...Bf5 (Or 5...e5! 6.Be3 exd4 7.Qxd4 Qxd4 8.Bxd4 Nc6 and Black is better.) 6.Bc4 e6 7.Qe2 Qxd4 8.Be3 Qxb2 9.Rd1 Bb4+ 10.Kf1 0–0 and 0–1 in 31. Le Goff - Girsh, chess.com 2022

5.Bc4: Targeting the vulnerable f7 square, this move is more aggressive and aims to put immediate pressure on black's position. Bc4 also prepares white to castle kingside quickly and supports the idea of recovering the pawn on e4 with a better-developed position. This move can lead to sharp play, as white seeks to exploit the lead in development and the weaknesses in black's camp, especially around the king.
and now:
5...Bf5 6.g4 Bg6 7.Ne2 e6 8.h4 h6 9.Nf4 Bh7 10.g5 e5 11.g6 exf4 12.Bxf7+ Ke7 13.Qe2 Qxd4 14.Bxf4 Bg8 15.Rd1 Qa4

5.Be3: This move develops a piece, supports the d4 pawn, and speeds up the possibility of queenside castling. White prepares to open up the center via f3. This move keeps the central tension and prepares for a kingside or central assault, depending on Black's responses.
