Caro-Kann Defense: von Hennig Gambit

Before the first move

The von Hennig Gambit is an aggressive, tactical weapon for White against the solid Caro-Kann. By sacrificing the e4-pawn early, White gains rapid development and attacking lanes against the f7-square. As Black, you must defend accurately to maintain your material advantage while White tries to blow open the center.

1. e4White

White opens with e4, the most popular move in chess. It immediately controls the d5 and f5 squares. While Black has many responses like the Sicilian Defense or the French Defense, the Caro-Kann is one of the sturdiest ways to challenge this central control.

1... c6Black · your move

Place your pawn on c6. This is the foundation of the Caro-Kann Defense, preparing to support a d5 push on the next move. Unlike the French Defense, this setup keeps the diagonal open for your light-squared bishop to develop later.

2. d4White

White plays d4, establishing a classical pawn center. While White could try the Hillbilly Attack with Bc4 or the Accelerated Panov with c4, the main line d4 is the most testing. Black's next move is almost always the central challenge d5.

2... d5Black · your move

Push your pawn to d5. This is the critical follow-up to your previous move, directly challenging White's e4-pawn and fighting for your share of the center. You are now ready to trade or force White to make a decision.

3. Nc3White

White plays Nc3, the most common response. Other major branches include the Advance Variation with e5 or the Exchange Variation. By developing the knight, White prepares to recapture on e4 if Black takes, or to support the center if Black maintains the tension.

Other paths here: e5 (Caro-Kann Defense: Advance Variation) · f3 (Caro-Kann Defense: Maróczy Variation) · Be3 (Caro-Kann Defense: Mieses Gambit) · Nd2 (Caro-Kann Defense: Modern Variation)

3... dxe4Black · your move

Capture the pawn on e4. By taking this pawn, you eliminate White's central spearhead and force White to decide how to respond. You are accepting the challenge and inviting White to prove they have compensation for the material.

Other paths here: Nf6 (Caro-Kann Defense: Campomanes Attack) · b5 (Caro-Kann Defense: Gurgenidze Counterattack) · g6 (Caro-Kann Defense: Gurgenidze System)

4. Bc4White

White plays Bc4, ignoring the pawn to pressure f7. This is much sharper than the standard recapture with Nxe4. White is following the spirit of the Rasa-Studier Gambit, hoping to catch Black off guard with rapid piece play and a direct attack on the king.

Other paths here: f3 (Caro-Kann Defense: Rasa-Studier Gambit) · Nxe4 (Caro-Kann: 4.Nxe4 Nf6)

Where you stand

The position is sharp and non-traditional for the Caro-Kann. White has sacrificed a pawn for rapid development and pressure on f7, while Black has a solid structure and an extra pawn. Black should focus on developing the kingside with Nf6 and e6, while White will likely play f3 or Qe2 to increase the pressure.
