Variations of the Blackmar-Diemer Gambit von Popiel Gambit Opening

There are several continuations and lines that black can follow after the pawn sacrifice, each with its own ideas and plans. Although we focus on the main line here, it is important to be aware of some variations to be prepared for different responses from black.

Black’s Defense with e6

One possible response from black after the pawn sacrifice is to play e6, aiming to solidify their center and prepare the development of their dark-squared bishop. This line leads to a more closed pawn structure and requires precise play from white to maintain the initiative.

Black’s Pawn Advance to e5

Another variation includes the black pawn advancing to e5, directly challenging white’s center and seeking to gain space. This line is more aggressive and can lead to an open game with attack possibilities for both sides.

The opening that arises with the moves 1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. Bg5

corresponds to a variation of the Blackmar-Diemer Gambit, specifically known as the von Popiel Gambit. This opening is bold and aggressive, aiming for rapid development and dominance in the center of the board in exchange for a pawn. The resulting position is rich in tactical and strategic opportunities for both sides. Below, we analyze strategies and tactics for both sides, as well as the best moves that can be played: Af5, e6, or Cc6.

Strategies and Tactics for White

Rapid Development and Control of the Center: By sacrificing a pawn early, white aims for quick development of their pieces and exerting pressure in the center of the board. The move 4. Bg5 is an example of this approach, attacking the knight on f6 and preparing for a quick castling.

Attack on the Black King: With the white king castling, white can plan an attack on the black king, leveraging their already developed pieces and the possibility of opening lines towards the opponent’s king.

Exploitation of Weaknesses: White must be alert to exploiting weaknesses in the black position, especially on dark squares, where the exchange of the dark-squared bishop can be a factor.

Strategies and Tactics for Black

Solid Defense and Counterplay: Although black has accepted the gambit, it is crucial to maintain a solid defense and seek counterplay opportunities. Coordination of black pieces is essential to repel white’s attacks.

Counterattack Options: Moves like Af5, e6, and Cc6 are critical for developing pieces to active squares, protecting the advanced pawn on e4, and preparing the ground for possible counterattacks. Af5 develops a piece while attacking c2, e6 prepares the development of the white-squared bishop and strengthens the center, while Cc6 develops another piece with the aim of centralizing it or supporting a pawn advance.

Utilizing the Extra Pawn: Although black has conceded some initiative, the extra pawn can be valuable in the middlegame and endgame. It is essential for black to either maintain this extra pawn or use it as a resource to gain material or positional advantage in the long run.


The Blackmar-Diemer Gambit, and particularly the von Popiel variation, presents a dynamic battlefield where white presses with rapid development and an attacking approach, while black seeks to counter these plans with solid defense and opportunities for counterplay. Moves Af5, e6, and Cc6 are key for black in their effort to neutralize white’s initiative and seek balance or even an advantage in the game.
