Vienna Gambit: 3...exf4

Before the first move

The Vienna Gambit is a provocative and sharp relative of the King's Gambit. White develops the knight to c3 first to control the center and prevent an early d5 counter-strike. By offering the f-pawn, White seeks to lure Black into an imbalanced battle where space and central control are traded for a temporary pawn advantage.

1. e4White · your move

Push your pawn to e4. This classic opening move claims space in the center and opens diagonal paths for your queen and light-squared bishop. It is the most direct way to start the fight for control of the board.

1... e5Black

Black replies with e5, entering the Open Game. While alternatives like the French Defense or Sicilian Defense are common, this move leads to the most classical struggles. Rare sidelines like the Barnes Defense or Borg Defense are much less reliable for Black.

2. Nc3White · your move

Develop your knight to c3. This is the hallmark of the Vienna Game. You protect your e4 pawn and keep the d5 square under surveillance while keeping your options open for the f-pawn's future advance.

2... Nf6Black

Black chooses Nf6, the most active defense against the Vienna. By attacking e4, you force White to make a decision. Other solid choices include the Max Lange Defense with Nc6, the Anderssen Defense with Bc5, or the more passive d6.

3. f4White · your move

Push your pawn to f4 to initiate the Vienna Gambit. You are offering a pawn to deflect Black's central pawn. If they accept, you will gain a massive center and a semi-open f-file for your future kingside attack.

3... exf4Black

Black accepts with exf4, diving into the complications of the Vienna Gambit accepted. This is a critical moment; many masters prefer the more solid d5 counter-strike or the d6 variation, but taking the pawn leads to the most tactical and double-edged positions.

Where you stand

The battle lines are drawn. White will likely push e5 to harass the knight on f6 and then develop the kingside rapidly to regain the f4 pawn. Black must decide whether to hold the extra pawn with g5 or focus on rapid development and a central counter-strike to punish White's slightly exposed king.

• e4-e5 Push e5 to kick the f6 knight
• g1-f3 Develop knight to control d4 and f4
• f6-g8 Retreat the knight if attacked by e5
