Vienna: 2...Bb4

Before the first move

The Vienna Game is a versatile opening where White develops the queenside knight early, keeping the f-pawn free to advance. Black's choice to pin that knight immediately with the bishop creates a sharp, provocative struggle for central control right from the start.

1. e4White · your move

Push your pawn to e4. This classic opening move claims space in the center and immediately opens lines for both your queen and your light-squared bishop to enter the game.

1... e5Black

Black replies with e5, leading to an Open Game. This is the most principled response, though you might occasionally see the Duras Gambit or the Barnes Defense from players looking to avoid main-line theory and create early imbalances.

2. Nc3White · your move

Develop your knight to c3. This is the defining move of the Vienna Game. You protect your e4 pawn and prepare for future central action without blocking your f-pawn's path.

2... Bb4Black

Black plays Bb4, a sharp and ambitious try. Instead of the standard Max Lange Variation with Nc6 or the solid Falkbeer with Nf6, Black chooses to pin your knight immediately, forcing you to address the tension on c3.

Where you stand

The position is tense and full of possibilities. White often responds by challenging the bishop with Nd5 or Qg4 to exploit the absence of the black bishop from the kingside. Black should focus on rapid development and deciding whether to trade the bishop for the knight or retreat after being challenged.
