Grünfeld Defense: Brinckmann Attack, Grünfeld Gambit

Before the first move

The Grünfeld Defense is a dynamic counter-attacking opening where Black allows White to build a large pawn center only to strike back at it immediately. In the Brinckmann Attack, White develops the dark-squared bishop early to f4, aiming for solid control and piece-based pressure rather than just relying on a massive wall of pawns.

1. d4White

White opens with d4, the most common way to start a positional battle. By controlling e5 and d4, White sets the stage for a Queen's Gambit or various Indian systems, forcing you to choose your defensive structure right away.

1... Nf6Black · your move

Develop your knight to f6. This is the most flexible response to d4, controlling the e4 and d5 squares while keeping your options open for several different defensive setups.

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

2. c4White

White plays c4, challenging the center and preparing to develop the knight to c3. While White could try the London System or the Trompowsky Attack, this classic approach invites you into the main lines of the Indian Defenses.

2... g6Black · your move

Push your pawn to g6. You are preparing to fianchetto your bishop on g7, where it will exert long-range pressure on the center. This move signals your intent to play either the King's Indian or the Grünfeld.

3. Nc3White

White plays Nc3, developing a piece and reinforcing the center. You now have a critical choice: you can play the King's Indian with d6, but the Grünfeld with d5 is the most direct way to challenge White's central ambitions.

Other paths here: d5 (Indian Defense: Anti-Grünfeld, Advance Variation) · f3 (Indian Defense: Anti-Grünfeld, Alekhine Variation) · h4 (Indian Defense: Anti-Grünfeld, Basman-Williams Attack) · g3 (King's Indian Defense: Fianchetto Variation, Immediate Fianchetto)

3... d5Black · your move

Strike at the center with d5. This is the defining move of the Grünfeld Defense. You are inviting White to capture or build a center that you will later attack with your pieces.

Other paths here: Bg7 (King's Indian: 3.Nc3 Bg7) · c5 (King's Indian: 3.Nc3 c5) · c6 (King's Indian: 3.Nc3 c6) · d6 (King's Indian: 3.Nc3 d6)

4. Bf4White

White chooses Bf4, a solid alternative to the more common Exchange Variation or the Russian System. By developing the bishop before playing e3, White maintains a very active piece setup and avoids the sharper, more theoretical lines.

Other paths here: e3 (Gruenfeld: 4.e3) · g3 (Gruenfeld: 4.g3) · g4 (Grünfeld Defense: Gibbon Gambit) · f3 (Grünfeld Defense: Lutikov Variation)

4... Bg7Black · your move

Fianchetto your bishop to g7. This piece is the soul of your position, putting pressure down the long diagonal and providing a safe home for your king after you castle.

5. e3White

White plays e3, reinforcing d4 and preparing to complete kingside development. While White sometimes tries the sharper Reshevsky Gambit with Rc1, this move is the most reliable way to maintain a stable advantage in the center.

5... O-OBlack · your move

Castle your king to safety. By moving your king to g8 and your rook to f8, you complete your initial development and prepare to begin your counter-attack in the center.

Other paths here: c5 (Gruenfeld: 4.Bf4 Bg7 5.e3 c5)

Where you stand

The position is balanced but full of tension. White has a solid center and well-placed pieces, while Black has a safe king and a powerful bishop on g7. Black's next goal is often to strike with c5 or Na6-c5, while White will look to complete development with Be2 and O-O, maintaining the central space advantage.

• c4-d5 White may trade on d5 to simplify.
• c7-c5 Black strikes the center with c5.
• b8-c5 Knight maneuvers to pressure d3 and c4.
• f1-e2 White develops the bishop to castle.
