Budapest Gambit Accepted

Indian Defense: Budapest Gambit Accepted arises when White takes the pawn offered by 2...e5 in the Budapest Gambit, also called the Budapest Defense. The capture gains a tempo against the f6-knight, so Black's third move decides where the knight goes and whether recovering the pawn comes first. Engines give White a slight edge. Lichess results are close to level, with White marginally ahead.

3...Ng4, the Main Line, is chosen in the large majority of games. The knight attacks e5, and the following moves revolve around that pawn. 4. Nf3, the Adler Variation, usually returns it in exchange for quick development. 4. e4, the Alekhine Variation, gives it back at once in order to build a broad pawn center. 4. Bf4, the Rubinstein Variation, allows White to try to keep the extra pawn, though doing so can mean accepting doubled c-pawns after ...Bb4+ and ...Bxc3+. The Fajarowicz Defense, 3...Ne4, is the less common alternative. Black makes no immediate effort to regain the pawn and instead centralizes the knight, looking for tactical chances built on ...Bb4+ and pressure against f2. The retreat 3...Ng8 is almost never played.
