Duras Gambit: what should White play?

Arising after Black's early pawn thrust, the Duras Gambit (ECO B00) confronts White with an immediate challenge on the f5 square. The objectively strongest and most popular response is exf5, which accepts the offered material and secures an engine evaluation of +1.71 across 1.29M recorded games (68.0% of the 1,901,553 games in the database). By capturing, White wins a central pawn and exposes weaknesses along Black's kingside.

Accepting the pawn with exf5

The capture exf5 directly refutes Black's early wing advance by establishing a material advantage while contesting the center. In an illustrative engine continuation, play develops along the sequence exf5 Nf6 d4 d5 Bd3 c5. Here, White anchors central space with the d4 pawn while naturally developing the f1 to d3, maintaining the extra pawn on f5 and leaving Black to search for compensation.

Pushing ahead with e5

White can also bypass the pawn by advancing e5, chosen in 15.3% of games (291K recorded) with an evaluation of +0.69. This advance denies Black immediate kingside activity and locks central space. The engine illustrates this branch with e5 d6 Nf3 Nc6 Bb5 dxe5, leading to a more closed structure where White pins the knight on c6 rather than immediately pocketing material.

Development alternatives

Other options preserve the tension while developing or protecting the central footprint. Both Nc3 (played in 11.5% of games, 218K recorded) and d3 (played in 5.2% of games, 98K recorded) offer an engine evaluation of +0.39, while the unconventional Nh3 carries an evaluation of +0.17. Although playable, these setups yield smaller advantages compared to simply claiming the pawn via exf5.
