Budapest Gambit
Initial Moves: 1.d4 Nf6 2.c4 e5
Strategic Summary & Main Idea
The Budapest Gambit offers a central pawn on move two to win it back with activity. The position after 2...e5 measures +0.81, one of the highest in this catalogue, and the number needs reading carefully: it measures the position before Black recovers the material. Once recovered, the main lines drop to +0.29 and +0.40 — an ordinary white edge, not a refutation. What this entry measures clearly is the difference between the gambit's two versions: the main one, with 3...Ng4, is playable; the Fajarowicz, with 3...Ne4, measures +3.16 and does not survive accurate play.
The pawn structure this opening produces
The Budapest's structure comes from the recapture on e5, and what remains afterwards decides the game. When Black recovers with a knight, the position leaves Black pawns on c7, d7, f7 and g7 against White pawns on c4 and none on d — that is, White has a queenside majority and Black has piece play in the centre. It is an endgame structure, which is why so many Budapest games end in simplified positions: Black trades to neutralise the space, and White needs the majority to convert. The e5 square is where everything meets: Black puts a knight there and White tries to trade it before it settles. The second structure appears in the Alekhine Attack with 4.e4: White returns the pawn and keeps two central pawns against none, which buys space at the cost of fragile dark squares — and the line measures +0.22, less than the quiet version. And when White simply declines with 3.d5, the position becomes an Old Indian in which Black has already spent ...e5: it measures −0.31, the only measured way for the gambit to come out better than it went in.
Typical Plans for White
- Hold the e5 pawn with Bf4 and Nf3 and return it only when the trade leaves the majority intact
- Decline the gambit with 3.d5, transposing into an Old Indian — and measuring −0.31, the worst choice here
- Play the Alekhine Attack with 4.e4, taking space at the cost of the dark squares
- Against the Fajarowicz, develop with a3 and Qc2 and punish the e4 knight: the line measures +3.16
- Convert the queenside majority in the endgame, the structural plan of the whole opening
Typical Plans for Black
- Recover the e5 pawn with a knight, at a moment when the capture does not lose the piece
- Pin with ...Bb4+ to win back the tempo the pawn recovery cost
- Install a knight on e5 and play against White's majority before it advances
- Choose 3...Ng4 rather than 3...Ne4: the measured difference between them is almost three pawns
- Accept the simplifications — Black's structure is fine in the endgame and poor in a piece middlegame

Frequently asked questions
Is the Budapest Gambit sound?
The main line is playable: after 3...Ng4 and the pawn recovery, the position measures +0.29, an ordinary white edge. What is not sound is the starting number — +0.81 after 2...e5 — because it measures the position before Black has the material back. Judging the gambit by that number is judging it at its worst possible moment.
Does the Fajarowicz Variation work?
No. With 3...Ne4 the knight has no support and Black never recovers the pawn: the position measures +3.16 against accurate play, and persisting after a3 leads to +2.00 a piece down. The difference between 3...Ng4 and 3...Ne4 is almost three pawns, the largest gap between two third moves in this whole catalogue.
How should White meet the Budapest?
By accepting and returning calmly. The line with 4.Bf4 measures +0.29 and the one with 4.Nf3 +0.40 — both give an edge without risk. What does not work is declining with 3.d5: the position becomes an Old Indian and measures −0.31, meaning Black comes out of the gambit better than he went in.

Common Mistakes & Where Most Amateurs Go Wrong
