Queen's Gambit Declined: Orthodox Defense, Classical Variation

Before the first move

The Orthodox Defense is a cornerstone of the Queen's Gambit Declined, where Black builds a solid, resilient structure. In this Classical Variation, both sides complete their development methodically, leading to a balanced middle game where Black seeks to liberate the position through central pawn breaks.

1. d4White

White opens with d4, the second most popular starting move. By controlling the center and preparing to develop the queenside, White invites a strategic battle. You'll often see this lead to the Queen's Gambit or various Indian Defenses.

1... d5Black · your move

Respond by moving your pawn to d5. This mirrors White's move, establishing your own foothold in the center and preventing White from easily pushing e4 to dominate 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 move of the Queen's Gambit. White isn't really losing a pawn; they're creating tension to undermine your center. You can accept the gambit, but the solid Declined lines are the backbone of elite play.

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

Support your center by moving your pawn to e6. This declines the gambit and creates a rock-solid chain of pawns. It also prepares to develop your kingside bishop so you can castle quickly.

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 develops the knight to c3, increasing the heat on d5. This is the most direct way to play, though White sometimes prefers Nf3 or the Exchange Variation with cxd5 to simplify the structure early on.

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

3... Nf6Black · your move

Bring your knight to f6. This is a vital developing move that controls the e4 and d5 squares while preparing for kingside castling. It is the most natural and strongest way to continue your development.

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, pinning your knight to the queen. This is the main line of the Queen's Gambit. White could also try the Exchange Variation or the London-style Bf4, but this pin is the most testing for Black.

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

Move your bishop to e7 to break the pin. This is a very safe developing move that prepares you to castle. It ensures that if White captures your knight, you can recapture with the bishop comfortably.

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

Black castles, completing the first phase of the opening. This is the standard approach, though some players prefer to insert h6 first to ask the bishop where it's going before committing the king's position.

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

Solidify your center with e3. This move supports the d4 pawn and opens a path for your light-squared bishop. You are building a very sturdy structure that is difficult for Black to break down.

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

6. Nf3White

White brings the knight to f3, a very flexible and strong developing move. White could also try Qc2 or Rc1 to wait and see how you deploy your queenside pieces before committing the knight.

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. In the Orthodox Defense, this knight often supports the other knight on f6 and prepares for the c5 or e5 pawn breaks that will eventually open up your position.

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 classic move in the Queen's Gambit. The rook eyes the c-file, which often becomes a highway for attacks. White could also develop the bishop to d3 or play the Rubinstein Variation with Qc2.

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

Move your pawn to c6. This solidifies your d5 pawn and creates a very resilient 'Triangle' structure. It also prepares for a later b6 and Bb7 or even a queen maneuver to b6 or a5.

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, completing their development. The bishop is well-placed here for both attack and defense. White sometimes tries a3 first to prevent any Bb4 ideas, but developing the bishop is the most direct path.

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 part of the 'Capablanca' simplifying maneuver. By taking the pawn, you force White's bishop to move again and prepare to challenge the center with your knight.

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. The bishop is now beautifully placed, but White has lost a tempo compared to if they had reached this square in one move. This is the start of the central skirmishes.

9... Nd5Black · your move

Jump your knight to d5. This centralizes your knight and attacks the bishop on g5. It is the start of a series of exchanges that will help you ease the pressure and free your cramped position.

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

10. Bxe7White

White accepts the trade on e7. By removing your dark-squared bishop, White hopes to exploit the slight lack of coordination in your remaining pieces. It's a very standard transition into the middle game.

10... Qxe7Black · your move

Recapture with your queen on e7. This brings your queen into the game and maintains your control over the center. It also connects your rooks, which is a key goal in any opening.

11. O-OWhite

White finally castles. Both kings are now tucked away, and the real strategic battle begins. White could have tried jumping the knight to e4 first, known as the Alekhine Variation, to keep more tension.

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

11... Nxc3Black · your move

Trade your knight for the one on c3. This further simplifies the position and removes a powerful piece that was controlling the center. It also forces White to decide how to recapture and shape their rook placement.

12. Rxc3White

White recaptures with the rook, maintaining a clean pawn structure. The rook on c3 is a bit unusual but very flexible; it can swing to the kingside or stay and pressure the c-file.

12... e5Black · your move

Push your pawn to e5. This is the critical liberating break for Black. It challenges White's center directly and opens up lines for your remaining bishop and queen. This is what you've been building toward.

13. dxe5White

White takes on e5. This leads to a mass simplification. White had other options like Bb3 or Qc2 to keep more pieces on the board, but taking on e5 is the most direct path to a solid, equal position.

Other paths here: Bb3 (QGD: Orthodox, Classical, 13.Bb3) · Qb1 (QGD: Orthodox, Classical, Maroczy, 13...exd4) · Qc2 (QGD: Orthodox, Classical, Vidmar, 13...e4)

13... Nxe5Black · your move

Recapture the pawn with your knight. Your knight is now excellently placed in the center of the board, and you have successfully neutralized White's early space advantage.

14. Nxe5White

White trades knights. This is the final major simplification of the opening phase. We are left with a very clean, symmetrical-looking position where the battle will revolve around the major pieces.

14... Qxe5Black · your move

Recapture with your queen. Your queen is now centralized and powerful. You have successfully navigated the opening and reached a middle game with equal chances and a very solid position.

Where you stand

The position is now completely equal. White will try to use the slightly more active bishop on c4 to create pressure, while Black will look to develop the light-squared bishop to f5 or g6 and challenge the c-file. Both sides should focus on rook coordination and king safety as the game transitions into a heavy-piece endgame.

• c8-f5 Develop bishop to an active square
• c3-h3 Swing rook to pressure the kingside
• f8-d8 Centralize the rook on the d-file
• c4-b3 Reposition bishop to a safer diagonal
• e5-g5 Pressure the kingside with the queen
