QGD: Marshall Defence, 3.cxd5
QGD: Marshall Defence, 3.cxd5
Definition
The Marshall Defence is an off-beat branch of the Queen’s Gambit Declined (QGD) that begins with the moves:
1. d4 d5 2. c4 Nf6 3. cxd5
After 3.cxd5 White immediately captures the central pawn. Black usually replies 3…Nxd5, letting the f6-knight recapture and maintain material balance while avoiding an isolated pawn.
Typical Move Order
The main tabiya arises after:
- 1. d4 d5
- 2. c4 Nf6 (the key Marshall move; Black declines the gambit by developing the king’s knight)
- 3. cxd5 Nxd5
- 4. e4 Nf6 5. Nc3 e5 or 4. Nf3 g6 → Grünfeld-like structures
Strategic Ideas
- For White
- Exploit the tempo loss of Black’s knight (f6→d5→f6) to seize space with e4.
- Build a classical pawn centre (e4–d4–c2) and launch a kingside attack.
- Choose between quiet development (Nc3, Nf3, e3) or sharper lines (e4, f4, Bc4).
- For Black
- Accept a slightly passive set-up in exchange for piece activity later.
- Strike at the white centre with …c5 or …e5 when the moment is right.
- Keep a flexible structure that can transpose to the Grünfeld, Chigorin, or even a kind of Semi-Tarrasch.
Historical Notes
The opening is named after the American grandmaster Frank J. Marshall, who first essayed 2…Nf6 against the Queen’s Gambit in tournament play (Breslau 1912, vs. Levitsky). Marshall sought fighting chances with Black rather than entering the solid but restrained Orthodox QGD.
The line never became fully mainstream because theory has long judged the immediate 2…Nf6 a shade inaccurate: Black wastes time with the knight and allows White to occupy the centre. Still, it survives as a surprise weapon and has been tried by creative players such as Bent Larsen, Alexander Morozevich, and Richard Rapport.

Critical Variations after 3.cxd5
- 4.e4 Nf6 5.Nc3 e6 6.Nf3 exd5 7.e5
The so-called “Central Expansion” where White gains a spatial bind and chances for a pawn storm. - 4.Nf3 g6 5.Nc3 Bg7
Black fianchettoes the bishop, steering into Grünfeld/King’s Indian terrain. - 4.e4 Nc3 c6 (Delayed Slav)
Black undermines d4 with …c6–…e5, transposing to Semi-Tarrasch-like play.
Typical Tactical Motifs
- Forks on e4–e5 hitting d6 or f6 due to the adventurous black knight.
- Pressure along the h1–a8 diagonal when White plays Bc4/Qb3 before Black castles.
- Break …c5 × d4 producing an isolated queen’s pawn (IQP) game.
Why You Might Adopt 3.cxd5
- To punish an opponent who expects mainstream QGD theory.
- To steer the game into open, tactical positions rather than the locked Orthodox structure.
- Because the resulting pawn structure resembles a Grünfeld where White has the move … but Black lacks the Grünfeld bishop on g7 (unless he spends more tempi).
Trivia & Anecdotes
- The ECO code for the Marshall Defence is D06. Adding 3.cxd5 narrows it to sub-codes D06-D07.
- Marshall reputedly adopted the line because he grew tired of “the dreary equality” in the Orthodox Queen’s Gambit; he preferred imbalance, even at slight objective cost.
- Modern engines rate the position after 3…Nxd5 around +0.5 for White—playable but indubitably risky for Black at the highest level.
Take-aways
3.cxd5 in the Marshall Defence is a principled challenge: White accepts Black’s gambit of tempi, dismantles the centre, and aims for rapid development and space. Black, in turn, relies on dynamic counterplay and transpositional tricks. While not considered theoretically best, it remains a rich field for creative experimentation and an excellent addition to a surprise-oriented opening repertoire.
