QGD: 4.Bg5 Nbd7 5.e3 c6 6.Nf3

Before the first move

The Queen's Gambit Declined is a cornerstone of classical chess. White fights for central control with the c4 thrust, while Black builds a solid, resilient structure. This specific line leads to the Cambridge Springs or Orthodox variations, focusing on solid development and central tension.

1. d4White · your move

Push your pawn to d4. This move claims space in the center and opens paths for your queen and dark-squared bishop. It is the foundation of many strategic openings where you aim for long-term control rather than immediate tactical chaos.

1... d5Black

Black replies with d5, the most solid response to the Queen's Pawn Game. This prevents White from building a massive center. While Black has many experimental options here like the Englund Gambit or the Dutch Defense, d5 remains the gold standard for reliability.

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

2. c4White · your move

Offer the c-pawn by moving it to c4. This is the Queen's Gambit. You are attacking Black's d5 pawn from the side, trying to lure it away from the center so you can eventually dominate the middle with your e-pawn.

Other paths here: Qd3 (Amazon Attack) · e4 (Blackmar-Diemer Gambit) · e3 (Queen's Pawn Game) · Bf4 (Queen's Pawn Game: Accelerated London System)

2... e6Black

Black chooses the Queen's Gambit Declined with e6. This is much more solid than the Queen's Gambit Accepted. Other sharp tries include the Slav Defense with c6 or the Chigorin Defense with Nc6, but e6 is the most classical way to maintain the center.

Other paths here: c5 (Queen's Gambit Declined: Austrian Defense) · Bf5 (Queen's Gambit Declined: Baltic Defense) · Nf6 (Queen's Gambit Declined: Marshall Defense) · b5 (Queen's Gambit Declined: Zilbermints Gambit)

3. Nc3White · your move

Develop your knight to c3. This piece adds direct pressure to the d5 square and prepares for central action. It is a natural developing move that keeps your options open while increasing the heat on Black's central structure.

Other paths here: Bf4 (QGD: 3.Bf4) · cxd5 (QGD: 3.cxd5) · e3 (QGD: 3.e3) · g3 (QGD: 3.g3)

3... Nf6Black

Black plays Nf6, the most flexible and common response. It reinforces the center and prepares for the future. Black could also try the Nimzo-Indian style with Bb4 or the Janowski Variation with a6, but Nf6 keeps the game in traditional channels.

Other paths here: Bb4 (QGD: 3.Nc3 Bb4) · Nc6 (QGD: 3.Nc3 Nc6) · Be7 (Queen's Gambit Declined: Charousek Variation) · a6 (Queen's Gambit Declined: Janowski Variation)

4. Bg5White · your move

Pin the knight to the queen by sliding your bishop to g5. This creates immediate pressure on Black's defense of the d5 pawn. By pinning the knight, you make it harder for Black to maintain their central foothold comfortably.

Other paths here: e3 (QGD: 3.Nc3 Nf6 4.e3) · g3 (QGD: Catalan without Nf3) · Bf4 (Queen's Gambit Declined: Harrwitz Attack) · Nf3 (QGD: 4.Nf3)

4... Nbd7Black

Black plays Nbd7, a standard move that sets up the famous Elephant Trap. If White captures on d5 and tries to win the knight on f6, Black has a winning tactical resource. More direct alternatives include Be7 or the sharp Manhattan Variation with Bb4.

Other paths here: Bb4 (QGD: 4.Bg5 Bb4) · c6 (QGD: 4.Bg5 c6) · dxc4 (QGD: 4.Bg5 dxc4) · c5 (Queen's Gambit Declined: Been-Koomen Variation)

5. e3White · your move

Solidify your center by moving your pawn to e3. This move defends d4 and opens the path for your light-squared bishop to develop. You are preparing to castle kingside and completing your central pawn structure.

Other paths here: Nf3 (QGD: 4.Bg5 Nbd7 5.Nf3)

5... c6Black

Black plays c6, reinforcing the d5 pawn and preparing a queenside counter-attack. This move often leads to the Cambridge Springs Defense if White is not careful. The main alternative here is Bb4, which leads to more forcing, tactical lines.

Other paths here: Bb4 (Queen's Gambit Declined: Manhattan Variation)

6. Nf3White · your move

Develop your knight to f3. This move completes your minor piece development on the kingside and prepares you to castle. You are now ready to fight for the center with all your forces coordinated and safe.

Other paths here: Qc2 (QGD: 4.Bg5 Nbd7 5.e3 c6 6.Qc2) · a3 (Queen's Gambit Declined: Capablanca Variation, Anti-Cambridge Springs Variation) · cxd5 (QGD: 4.Bg5 Nbd7 5.e3 c6 6.cxd5 cxd5)

Where you stand

The position is rich with strategic depth. White will likely castle and look to expand in the center or on the queenside. Black has a very solid shell and will aim to break out with c5 or launch a queenside attack using the queen on a5. Both sides must balance their development with the looming central tension.

• d1-c2 Develop the queen to support the center
• d8-a5 Counter-attack with the Cambridge Springs maneuver
• f1-e2 Prepare for kingside castling
• c6-c5 Challenge the center with a pawn break
