Budapest: 3...Ng4 4.e3

Before the first move

The Budapest Gambit is a provocative response to the Queen's Gambit where Black sacrifices a central pawn immediately. By playing 3...Ng4, Black aims to regain the pawn on e5 while disrupting White's development. White must choose between clinging to the extra material or focusing on solid positional control.

1. d4White · your move

Move your pawn to d4 to claim immediate control of the center. This classic opening move opens lines for your queen and dark-squared bishop while preventing Black from easily placing a pawn on e5.

1... Nf6Black

Black replies with Nf6, the most common response to the Queen's Pawn Opening. By avoiding d5, Black remains flexible, though alternatives like the English Defense with b6 or the sharp Englund Gambit with e5 are also possible.

Other paths here: Na6 (Australian Defense) · g5 (Borg Defense: Borg Gambit) · b6 (English Defense) · e5 (Englund Gambit)

2. c4White · your move

Push your pawn to c4 to challenge Black's influence and prepare to gain more space. This move is the hallmark of the Queen's Gambit family, intending to solidify your grip on the d5-square.

2... e5Black

Black surprises White with the Budapest Gambit, e5. This is a sharp alternative to more solid choices like the Nimzo-Indian with e6 or the King's Indian setup with g6. Black aims for active piece play at the cost of a pawn.

Other paths here: g5 (Indian Defense: Medusa Gambit) · b5 (Indian Defense: Pyrenees Gambit) · a6 (Indian: 2.c4 a6) · Nc6 (Mexican Defense)

3. dxe5White · your move

Capture the pawn on e5. Accepting the gambit is the most principled response, challenging Black to prove they have enough compensation for the lost material while you try to consolidate your advantage.

Other paths here: d5 (Budapest: 3.d5) · e3 (Budapest: 3.e3)

3... Ng4Black

Black plays Ng4, the most popular way to try and recover the pawn. The main alternative is the Fajarowicz Variation with Ne4, which leads to very different tactical patterns and avoids the immediate hunt for the e5-pawn.

Other paths here: Ne4 (Indian Defense: Budapest Defense, Fajarowicz Variation)

4. e3White · your move

Push your pawn to e3 to reinforce your center and open a path for your light-squared bishop. You are choosing a solid setup that prioritizes development over desperately trying to defend the extra pawn on e5.

Other paths here: Nf3 (Indian Defense: Budapest Defense, Adler Variation) · e4 (Indian Defense: Budapest Defense, Alekhine Variation) · Bf4 (Indian Defense: Budapest Defense, Rubinstein Variation)

Where you stand

The position is balanced but strategically rich. Black will likely recapture the pawn on e5 with the knight, while White focuses on completing development and controlling the center. Both sides must be careful: White aims for a small positional edge, while Black relies on active piece play to maintain the equilibrium.

• g4-e5 Recapture the pawn on e5
• f1-e2 Develop bishop and prepare castling
• b8-c6 Add pressure to the center
• g1-f3 Control the center and castle
