Queen's Gambit Declined: Orthodox Defense, Classical Variation

Before the first move

The Orthodox Defense is a cornerstone of the Queen's Gambit Declined. Black accepts a slightly cramped position in exchange for a solid, rock-like structure. The battle centers on White's spatial advantage versus Black's patient efforts to simplify and eventually strike back in the center with e5 or c5.

1. d4White

White starts with d4, a move that focuses on long-term control and solid structures. While e4 leads to open games, d4 often leads to more closed, maneuvering battles. Alternatives like Nf3 or c4 are also popular ways to start.

1... d5Black · your move

Move your pawn to d5. By matching White's central claim, you prevent White from playing e4 and establish your own foothold in the middle of the board.

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

2. c4White

White plays c4, the signature gambit move. White isn't really losing a pawn, as they can usually win it back later. Alternatives include the London System with Bf4 or the Chigorin with Nc3.

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 · your move

Push your pawn to e6. This declines the gambit and reinforces your d5-pawn. It creates a very solid chain, though it does temporarily block in your light-squared bishop.

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

White plays Nc3, the most natural developing move. White develops toward the center and increases the tension. White could also choose the Exchange Variation with cxd5 or the slower Nf3.

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

3... Nf6Black · your move

Develop your knight to f6. This is a crucial defensive move, controlling the e4 and d5 squares while preparing for kingside castling.

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

White plays Bg5, the most aggressive setup. By pinning the knight, White makes the center more volatile. White could also play Bf4 or the quieter e3 to keep things solid.

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... Be7Black · your move

Develop your bishop to e7. This move breaks the pin on your knight and prepares you to castle. It is a humble but essential step in the Orthodox Defense.

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

White plays e3, a solid choice that completes the central pawn triangle. White could also try the Exchange Variation here by playing cxd5, or develop the other knight with Nf3.

Other paths here: Nf3 (QGD: 4.Bg5 Be7 5.Nf3) · Bxf6 (Queen's Gambit Declined: Modern Variation, Heral Variation) · cxd5 (QGD: 4.Bg5 Be7 5.cxd5 Nxd5)

5... O-OBlack · your move

Castle your king to the kingside. This tucks your king away to safety and brings your rook closer to the action in the center.

Other paths here: h6 (QGD: 4.Bg5 Be7 5.e3 h6) · Nbd7 (QGD: 4.Bg5 Be7 5.e3 Nbd7)

6. Nf3White

White plays Nf3, continuing the classical development. White is preparing to castle and keeping an eye on the e5 square. Alternative setups include Qc2 or Rc1.

Other paths here: Qc2 (QGD: 4.Bg5 Be7 5.e3 O-O 6.Qc2) · Rc1 (QGD: Anti-Neo-Orthodox Variation)

6... Nbd7Black · your move

Develop your knight to d7. From here, the knight supports the f6 knight and prepares to help with the eventual c5 or e5 pawn breaks.

Other paths here: b6 (QGD: 6.Nf3 b6) · Ne4 (QGD: Lasker without ...h6) · h6 (QGD: Neo-Orthodox, 7.Bh4)

7. Rc1White

White plays Rc1, a prophylactic move against Black's future c5 break. White could also develop the bishop to d3 immediately or play Qc2 to connect the rooks.

Other paths here: Bd3 (QGD: Orthodox, Botvinnik Variation) · Qb3 (QGD: Orthodox, Rauzer Variation) · Qc2 (QGD: Orthodox, Rubinstein Variation) · cxd5 (QGD: Orthodox, 7.cxd5 Nxd5)

7... c6Black · your move

Push your pawn to c6. This further reinforces your d5 point and prepares a retreat square for your queen or a future b5 expansion.

Other paths here: b6 (QGD: Orthodox, 7.Rc1 b6) · dxc4 (QGD: Orthodox, 7.Rc1 dxc4) · h6 (QGD: Orthodox, 7.Rc1 h6) · Re8 (QGD: Orthodox, 7.Rc1 Re8)

8. Bd3White

White plays Bd3, finally developing the last minor piece. White is now fully ready to castle. An alternative was Qc2, which also eyes the kingside but stays more flexible.

Other paths here: a3 (QGD: Orthodox, 7.Rc1 c6 8.a3) · Qc2 (QGD: Orthodox, Rubinstein Attack, 8...dxc4)

8... dxc4Black · your move

Capture the pawn on c4. This is a key timing move. By waiting for White to move the bishop once, you force White to move it again to recapture, winning a small tempo.

Other paths here: a6 (QGD: Orthodox, Main Line, 8...a6) · h6 (QGD: Orthodox, Main Line, 8...h6) · Re8 (QGD: Orthodox, Main Line, 8...Re8)

9. Bxc4White

White recaptures with Bxc4. This is forced to maintain material balance. The bishop is well-placed here, but Black has achieved the first step of their freeing maneuver.

9... Nd5Black · your move

Move your knight to d5. This centralizes the knight and challenges White's bishop on g5. You are looking to trade pieces to ease your slightly cramped position.

Other paths here: b5 (QGD: Orthodox, Main Line, Fianchetto Variation)

10. Bxe7White

White plays Bxe7, accepting the trade. White could also retreat the bishop to f4, but trading is the most direct way to keep the game under control.

10... Qxe7Black · your move

Capture the bishop with your queen. This recaptures material and connects your rooks, while keeping your queen active in the center.

11. O-OWhite

White castles, finishing their development. White maintains a slight space advantage. A rare alternative is Ne4, trying to provoke further trades or weaknesses.

Other paths here: Ne4 (Queen's Gambit Declined: Orthodox Defense, Alekhine Variation)

11... Nxc3Black · your move

Capture the knight on c3. By trading your well-placed knight, you damage White's pawn structure or force a rook to an awkward square, further simplifying the game.

12. Rxc3White

White recaptures with Rxc3. Recapturing with the pawn would also be possible but would create a structural weakness. The rook now guards the third rank.

12... e5Black · your move

Push your pawn to e5. This is the liberating break you have been preparing for. It challenges White's center directly and opens lines for your remaining pieces.

Where you stand

The position is nearly equal. White maintains a slight lead in development and a more active rook, but Black has successfully liberated their position with e5. The future battle will revolve around the d4-e5 pawn tension and whether White can use the semi-open c-file to create pressure against Black's queenside.

• d4-d5 White pushes d5 to create central tension
• c3-h3 White rook maneuvers to support the kingside
• d7-f6 Black knight improves its position on f6
• c8-e6 Black bishop finally develops to an active square
