Grünfeld Defense: Exchange Variation, Classical Variation

Before the first move

The Grünfeld Defense is a dynamic counter-attacking opening where Black allows White to build a massive pawn center, only to immediately strike back with pieces and well-timed pawn breaks. In this Exchange Variation, you trade space for activity, aiming to prove that White's center is more of a target than an asset.

1. d4White

White starts with d4, the most common way to control the center and prepare for a queen-pawn opening. You'll need to decide whether to meet this with a mirror move like d5 or a more flexible response.

1... Nf6Black · your move

Develop your knight to f6. This flexible move controls the e4 and d5 squares, preventing White from immediately occupying the center with a second pawn while keeping your options open.

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

2. c4White

White plays c4, the standard follow-up to d4, aiming for a Queen's Gambit style structure. White could also try the London System with Bf4 or the Fianchetto with g3, but c4 is the most ambitious try for an advantage.

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 · your move

Push your pawn to g6. This prepares the fianchetto of your bishop to g7, where it will exert long-range pressure along the great diagonal toward the center.

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

3. Nc3White

White develops the knight to c3, a natural and strong move that contests the center. White could also choose f3 or g3 to avoid the main theoretical lines, but this is the most direct way to challenge Black's setup.

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, challenging White's c4 pawn and inviting an immediate confrontation in the heart of the board.

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. cxd5White

White enters the Exchange Variation with cxd5. This is the most critical test of the Grünfeld. White could also try quieter moves like e3 or g3, or even the aggressive Stockholm Variation with Bg5.

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

4... Nxd5Black · your move

Recapture the pawn with your knight on d5. This places your knight in a powerful central position, though you must be ready for White to kick it away soon.

5. e4White

White plays e4, seizing the full center and attacking the knight. This is the main line, though White sometimes tries the more patient Bd2 or the Nadanian Attack with Na4 to disrupt Black's coordination.

Other paths here: Bd2 (Gruenfeld: Exchange, 5.Bd2) · g3 (Gruenfeld: Exchange, 5.g3) · Na4 (Grünfeld Defense: Exchange Variation, Nadanian Attack)

5... Nxc3Black · your move

Trade your knight for the one on c3. Since your knight is under attack, you simplify the position and create a structural weakness in White's camp by doubling their pawns.

Other paths here: Nb6 (Gruenfeld: Exchange, 5.e4 Nb6)

6. bxc3White

White recaptures with bxc3. White now has a massive pawn center (c3, d4, e4), but the c3 pawn is a potential target for Black's pieces later in the game.

6... Bg7Black · your move

Fianchetto your bishop to g7. From this square, your bishop becomes a monster, putting immense pressure on the d4 pawn and the entire long diagonal.

Other paths here: c5 (Gruenfeld: Exchange, 5.e4 Nxc3 6.bxc3 c5)

7. Bc4White

White chooses the Classical Variation with Bc4, the most direct and attacking setup. Other major options include the Modern Exchange with Nf3 or the subtle Be3, both of which aim to solidify the center differently.

Other paths here: Ba3 (Gruenfeld: Exchange, 7.Ba3) · Bb5+ (Gruenfeld: Exchange, 7.Bb5+) · Be3 (Gruenfeld: Exchange, 7.Be3) · Nf3 (Grünfeld Defense: Exchange Variation, Modern Exchange Variation)

Where you stand

White has achieved a massive pawn center and active piece play, while Black has a solid kingside and powerful pressure against d4. The coming battle revolves around Black's c5 break and White's ability to maintain the central wall. Both sides have clear targets, and the position remains highly tactical and sharp.

• c7-c5 Challenge the d4 pawn immediately
• c8-e3 Develop the bishop to pin or pressure
• g1-e2 Develop the knight to support d4
• e1-g1 Protect the king and connect rooks
• b8-c6 Add more pressure to the d4 pawn
