QGD Tarrasch: 4.cxd5

Before the first move

The Tarrasch Defense is an ambitious way to fight the Queen's Gambit. By playing c5, Black accepts an isolated queen's pawn in exchange for free piece development and central space. White's goal is to prove that the structural weakness of that pawn outweighs Black's active play.

1. d4White · your move

Push your pawn to d4. This move claims the center and opens paths for your queen and dark-squared bishop. It is the foundation of most closed games, focusing on long-term positional control rather than immediate tactical skirmishes.

1... d5Black

Black replies with d5, establishing a symmetric presence in the center. While the Horwitz Defense with e6 or the English Defense with b6 are interesting alternatives, d5 remains the most direct way to challenge White's spatial ambitions.

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

2. c4White · your move

Offer the c4 pawn to challenge Black's central control. This is the Queen's Gambit. You are inviting Black to trade their central d5 pawn for your flank c-pawn, which would give you a stronger presence in the very center of the board.

2... e6Black

Black chooses the solid e6, declining the gambit. This is more traditional than the Chigorin Defense with Nc6 or the Baltic Defense with Bf5. By reinforcing d5, Black prepares for a long struggle where their structure remains intact.

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 move puts immediate pressure on the d5 square and prepares for central expansion. It is a flexible developing move that keeps your options open for various setups, including the Exchange Variation or the Main Line.

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

3... c5Black

Black plays c5, the Tarrasch Defense. This is much more active than the Janowski Variation with a6 or the Semi-Slav with c6. Black accepts the possibility of an isolated d-pawn in exchange for rapid development and piece activity.

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. cxd5White · your move

Capture the pawn on d5. By trading now, you force Black to make a decision about their pawn structure. This is the most direct way to head toward the main lines where Black will likely end up with an isolated queen's pawn on d5.

Other paths here: e3 (QGD Tarrasch: 4.e3) · Nf3 (QGD Tarrasch: 4.Nf3)

Where you stand

The battle lines are drawn around the d5 square. White will try to blockade and eventually capture the isolated d5 pawn, while Black will use their superior piece activity to launch an attack or maintain the balance. Both sides have clear targets and plenty of room for creative play in the resulting middlegame.

• g1-f3 Develop the knight to control d4
• e6-d5 Recapture to establish the isolated pawn
• c1-g5 Pin the knight to pressure d5
• b8-c6 Develop the knight to support d5
