Gruenfeld: 4.Bf4 Bg7

Before the first move

The Grünfeld Defense is a dynamic counter-attacking opening where Black allows White to build a large center only to strike back at it immediately. In this Bf4 variation, White adopts a solid, classical setup to pressure d5 and maintain control without the immediate chaos of the Exchange Variation.

1. d4White · your move

Move your pawn to d4 to claim central space and open lines for your queen and dark-squared bishop. This stable first move sets the stage for a strategic battle where you control the pace of the game.

1... Nf6Black

Black responds with Nf6, the most common reply to d4. By avoiding d5 immediately, Black keeps the game flexible. Other popular alternatives include the sharp Englund Gambit with e5 or the solid Horwitz Defense with e6.

2. c4White · your move

Push your pawn to c4. This is the standard follow-up to d4, putting pressure on the d5 square and preparing to develop your knight behind the pawn. You are building a powerful central wedge.

2... g6Black

Black chooses g6, preparing a hypermodern setup. By fianchettoing the bishop, Black intends to attack the center from the wings. Black could also choose the solid Queen's Indian with b6 or the Mexican Defense with Nc6.

3. Nc3White · your move

Develop your knight to c3. This move puts direct pressure on the d5 square and prepares for a full central occupation. It is the most ambitious way to challenge Black's kingside setup.

3... d5Black

Black plays d5, the definitive move of the Grünfeld. If Black had played Bg7 first, it would remain a King's Indian Defense. Now, the central tension is established, and White must decide how to handle the d5 pawn.

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 · your move

Bring your bishop to f4. This active square develops a piece while putting pressure on the d5 pawn and the c7 square. It avoids the massive complications of the Exchange Variation while maintaining a slight edge.

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

4... Bg7Black

Black completes the fianchetto with Bg7. The bishop is now a powerful long-range attacker. White will likely continue with e3 to solidify the center, while Black prepares to castle and eventually strike with c5.

Where you stand

The position is rich with strategic depth. White will focus on solidifying the center with e3 and developing the kingside, while Black aims to undermine the white center with moves like c5 or Nc6. Both sides have clear development paths, and the battle will revolve around whether White's central space outweighs Black's piece activity.
