Queen's Gambit

1. d4 d5 2. c4

The Queen's Gambit is one of the oldest openings in chess — older than the Ruy López — and it remains the most respected 1. d4 opening at the top level. Unlike most gambits, the pawn White offers on c4 cannot be safely held. Black's real decision is not whether to take the pawn but how to respond to White's threat to build a large centre.

The Netflix series The Queen's Gambit introduced the opening to a new audience; the opening itself has been the backbone of World Championship matches from Steinitz's era to Carlsen's.

The core idea

After 1. d4 d5 2. c4, White pressures the d5 pawn from a second direction. Black has three main choices:

• Decline with 2... e6 (QGD) or 2... c6 (Slav)
• Accept with 2... dxc4 (QGA)
• Counter-gambit with 2... e5 (Albin) or 2... c5 (Symmetrical/Tarrasch-style)

The first two choices dominate serious play. The Albin and similar counters appear occasionally as surprise weapons.

Main variations

Queen's Gambit Declined (QGD) — 1. d4 d5 2. c4 e6

The most classical response. Black supports the d5 pawn with the e-pawn, locking in the c8 bishop but keeping a solid central grip. Main lines:

• 3. Nc3 Nf6 4. Bg5 Be7 (Orthodox) — classical main line; 5. e3 or 5. Nf3 leads to rich middlegame play
• 3. Nc3 Nf6 4. Bg5 Nbd7 5. e3 c6 6. Nf3 Qa5 (Cambridge Springs) — Black attacks c3 and the bishop on g5
• 3. Nc3 Nf6 4. cxd5 exd5 (Exchange Variation) — White locks in the symmetrical pawn structure and plays a minority attack on the queenside
• 3. Nf3 Nf6 4. Nc3 Be7 5. Bg5 h6 6. Bh4 O-O 7. e3 Ne4 (Lasker Defense) — Emanuel Lasker's simplification idea
• Tartakower Defense (... b6) — Black fianchettoes the c8 bishop via b7
• Ragozin (3... Nf6 4. Nf3 Bb4) — hybrid between QGD and Nimzo-Indian

The QGD is deeply respected and almost unrefutable. Every world champion has played it. It's the standard choice for Black players who want a solid game against 1. d4.

Slav Defense — 1. d4 d5 2. c4 c6

Black supports d5 with the c-pawn instead of the e-pawn. This keeps the light-squared bishop's diagonal open — the main drawback of the QGD is that c8 bishop's development. Main Slav lines:

• Main Line Slav (3. Nf3 Nf6 4. Nc3 dxc4 5. a4 Bf5) — classical; Black develops the bishop to f5 before closing the pawn structure
• Semi-Slav (3. Nf3 Nf6 4. Nc3 e6) — Black plays both ... c6 and ... e6, preparing ... dxc4 and ... b5 to hold the pawn
• Meran (... dxc4 followed by ... b5) — sharp sub-variation inside the Semi-Slav
• Botvinnik Variation — the wildest Semi-Slav line, with tactical fireworks from both sides
• Exchange Slav (3. cxd5 cxd5) — symmetric, drawish

Queen's Gambit Accepted (QGA) — 1. d4 d5 2. c4 dxc4

Black grabs the pawn. The pawn cannot be held: after 3. Nf3 Nf6 4. e3, White will regain the pawn with Bxc4. The QGA is a pragmatic choice — Black aims for simple development and a solid middlegame rather than trying to keep the extra pawn.

Main lines after 3. Nf3 Nf6 4. e3: - Classical (4... e6 5. Bxc4 c5) — symmetric pawn tension in the centre - 4... a6 — preparing ... b5 before White can play a4 - 4... Bg4 — developing the light-squared bishop first

The QGA is considered fully sound and shows up regularly in top-level play.

Minor tries

• Albin Counter-gambit (2... e5) — Black sacrifices a pawn for activity. Dubious against accurate play, but fun at club level.
• Marshall Defense (2... Nf6) — offbeat; usually transposes to other Gambit lines.
• Baltic Defense (2... Bf5) — develops the bishop before it gets locked in. Playable but not inspiring.

Canonical games to study

• Lasker – Capablanca, St. Petersburg 1914 — QGD Exchange; classical minority attack technique.
• Alekhine – Capablanca, Buenos Aires 1927 (WCC), Game 34 — QGD; a key game in the match that crowned Alekhine.
• Botvinnik – Petrosian, Moscow 1963 (WCC), Game 7 — Semi-Slav; the Botvinnik Variation at its most complex.
• Kasparov – Karpov, Seville 1987 (WCC), Game 24 — QGD; Kasparov must win to retain his title, and does.
• Kramnik – Topalov, Elista 2006 (WCC), Game 2 — Slav; the match that reunified the title.
• Carlsen – Anand, Sochi 2014 (WCC), Game 6 — QGD; modern endgame grinding by Carlsen.

Practical advice

1. Play the QGD first. If you're new to 1. d4 d5, the QGD's structures are the most instructive. You'll learn the minority attack, classical piece play, and thematic pawn breaks. Then branch into Slav or QGA once those ideas are second nature.
2. The c8 bishop is the problem piece in the QGD. Solutions include the Tartakower (... b6 and ... Bb7), the Capablanca Freeing Manoeuvre (... dxc4 followed by ... c5), and the Lasker Defense (piece trades). Know at least one.
3. In the Slav, choose a line that fits your style. The Main Line Slav is solid and structural. The Semi-Slav is sharp and tactical. They're practically different openings.
4. Don't try to hold the gambit pawn in the QGA. Give it back and play for equal development. Holding with ... b5 is risky and gives White attacking chances.
5. Watch minority attack games. The QGD Exchange pawn structure shows up in thousands of games; understanding the minority attack (White's b4-b5 break against c6) is a foundational endgame/middlegame pattern.
