Neo-Gruenfeld: 4.cxd5

Before the first move

The Neo-Gruenfeld with 4.cxd5 is a sophisticated hybrid that combines the hypermodern spirit of the Gruenfeld with the solid positional foundations of the Catalan. White aims to dissolve the center early, while Black seeks to prove that their active piece play and fianchettoed bishop provide enough compensation for White's central space.

1. d4White · your move

Push your pawn to d4. This move claims the center immediately and opens lines for your queen and dark-squared bishop, setting the stage for a principled positional battle.

1... Nf6Black

Black replies with Nf6, the most common and flexible response to d4. While Black could try the Englund Gambit with e5 or the solid Horwitz Defense with e6, the knight move keeps all options open.

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

2. c4White · your move

Advance your pawn to c4. By challenging the d5 square and gaining more space on the queenside, you are preparing to build a powerful pawn duo in the center.

Other paths here: f4 (Canard Opening) · g4 (Indian Defense: Gibbins-Weidenhagen Gambit) · e4 (Indian Defense: Omega Gambit) · d5 (Indian Defense: Pawn Push Variation)

2... g6Black

Black chooses g6, steering the game toward hypermodern territory. You might also see the Mexican Defense with Nc6 or the Queen's Indian Accelerated with b6, but g6 is the most ambitious for a kingside fianchetto.

Other paths here: g5 (Indian Defense: Medusa Gambit) · b5 (Indian Defense: Pyrenees Gambit) · a6 (Indian: 2.c4 a6) · Nc6 (Mexican Defense)

3. g3White · your move

Push your pawn to g3. You are mirroring Black's setup to create a solid Catalan-style structure where your light-squared bishop will exert tremendous pressure from g2.

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) · Bg5 (King's Indian: 3.Bg5)

3... d5Black

Black plays d5, transitioning into the Neo-Gruenfeld. If Black had played Bg7 instead, the game would remain in King's Indian territory, but d5 forces an immediate confrontation in the middle of the board.

Other paths here: Bg7 (King's Indian: 3.g3)

4. cxd5White · your move

Capture the pawn on d5. By trading now, you clarify the central tension and prepare to build a large pawn center with e4 after Black recaptures with the knight.

Other paths here: Bg2 (Neo-Gruenfeld: 4.Bg2)

Where you stand

The position is strategically rich. White will typically follow up with Bg2 and e4 to establish a massive pawn center. Black's plan involves putting pressure on that center using the g7-bishop, the c5-break, and active knight maneuvers. Both sides must balance their development carefully to avoid falling behind in the tactical skirmishes ahead.

• f1-g2 Fianchetto the light-squared bishop to g2
• e2-e4 Build a dominant pawn center with e4
• f8-g7 Fianchetto the bishop to pressure the center
• f6-d5 Recapture the pawn to centralize the knight
• c7-c5 Challenge the white center with the c5-break
