QGD: Orthodox, Rubinstein Variation

Before the first move

The Queen's Gambit Declined: Orthodox Defense is one of the most solid and respected replies to the Queen's Gambit. White seeks space and a central squeeze, while Black aims for a robust defensive structure, looking to neutralize the pressure before eventually liberating the position with a central break.

1. d4White · your move

Push your pawn to d4. This move immediately claims central space and opens lines for your queen and dark-squared bishop. It is the foundation for many positional and tactical systems, setting a deliberate pace for the game.

1... d5Black

Black replies d5, the most classical response to d4. While alternatives like the English Defense with b6 or the sharp Englund Gambit with e5 exist, d5 remains the gold standard for solidity and central control.

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

2. c4White · your move

Push your pawn to c4. This is the Queen's Gambit. You are offering a pawn to divert Black's d-pawn away from the center, which would allow you to eventually occupy 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 plays e6, entering the Queen's Gambit Declined. By refusing the pawn, Black maintains a firm grip on d5. Sharp alternatives include the Chigorin Defense with Nc6 or the Austrian Defense with c5, but e6 is the most reliable.

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 increases the pressure on the d5 square and prepares to control the center. It is a natural developing move that keeps your options open for the kingside pieces.

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 main line of the QGD. This develops a piece toward the center and prepares for safety. Black could also try the Janowski Variation with a6 or the Semi-Slav with c6, but Nf6 is the most classical approach.

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

Develop your bishop to g5. This creates an annoying pin on the f6 knight against the queen. It forces Black to address the pressure on the kingside and often leads to a trade or a defensive retreat.

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

Black replies Be7, unpinning the knight and preparing to castle. This is the heart of the Orthodox Variation. Other tries like the Modern Variation with Nbd7 or the sharp c5 have their merits, but Be7 is the most solid.

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

Push your pawn to e3. This move solidifies your center and opens the path for your light-squared bishop. You are building a very stable foundation before deciding where to commit your other pieces.

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

Black castles O-O, securing the king. This is almost always the next step for Black. Some players prefer to play h6 first to ask the bishop its intentions, but castling immediately is perfectly standard and safe.

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

6. Nf3White · your move

Develop your knight to f3. This move completes your minor piece development on the kingside and prepares you to castle. It also adds more control over the e5 square, a key battleground in this opening.

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

6... Nbd7Black

Black plays Nbd7, a classic QGD move. The knight on d7 is very flexible, supporting the center. Black could also try the Lasker Defense with Ne4 or the Neo-Orthodox h6, but Nbd7 stays within the Rubinstein system.

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

7. Qc2White · your move

Slide your queen to c2. This move is the Rubinstein Variation. You are placing the queen on a useful diagonal, eyeing the kingside and preparing to connect your rooks while keeping an eye on the c-file.

Other paths here: Bd3 (QGD: Orthodox, Botvinnik Variation) · Qb3 (QGD: Orthodox, Rauzer Variation) · Rc1 (QGD: Orthodox, 7.Rc1) · cxd5 (QGD: Orthodox, 7.cxd5 Nxd5)

Where you stand

The position is a classic battle of maneuvering. White has a slight space advantage and will likely look to expand on the queenside or pressure the center. Black remains very solid and will aim for the c5 or e5 pawn breaks to liberate the pieces and challenge White's central control. Both sides have clear, logical plans for the middlegame.

• a1-c1 Place the rook on the open c-file
• f1-d3 Develop the bishop to an active diagonal
• c7-c5 Challenge the center with the c5 break
• d7-b6 Prepare to fianchetto the light-squared bishop
