Nimzowitsch Defence: 2.d4 d5 3.exd5 Qxd5 4.Nf3
Nimzowitsch Defence: 2.d4 d5 3.exd5 Qxd5 4.Nf3
Definition
The position arises from the move sequence 1. e4 Nc6 2. d4 d5 3. exd5 Qxd5 4. Nf3. It belongs to the broader family of the Nimzowitsch Defence, named after the hyper-modern pioneer Aron Nimzowitsch. Black’s 1…Nc6 invites White to occupy the centre, intending to undermine it later. After 2.d4 d5, Black challenges the e4–d4 pawn duo directly. White captures on d5, and Black recaptures with the queen; 4.Nf3 develops with tempo on the queen, forcing her to decide between maintaining an active post or retreating, usually to d6, a5 or e4.
Strategic Themes
- Early Queen Activity vs. Development: Black’s queen sortie gains space but may become a target. White aims to develop rapidly and exploit tempi gained by attacking the queen.
- Hyper-modern Central Strategy: Unlike classical openings where pawns occupy the centre, Black relies on piece pressure (…Bg4, …O-O-O, …e5) to undermine White’s pawns.
- Pawn Structure: The central pawns are already exchanged on d5, leaving an open e-file that both sides may contest with Re1 or …Re8. The absence of the d-pawn also facilitates Black’s …e5 break.
- King Safety Choices:
- Black can castle kingside after …Nf6, …Bg4 and …e6, reaching a solid French-like set-up without the usual light-squared-bishop problem.
- Alternatively, Black may castle long (…O-O-O) and launch a pawn storm on the kingside, especially if the queen remains on a5 or e4.
Main Variations after 4.Nf3
- 4…Bg4 5.Be2 O-O-O – Black pins the knight, castles long and prepares …e5.
- 4…e5 5.Nc3 Bb4 – Direct central counter-strike; the game often transposes to Scotch or Vienna-type structures.
- 4…Nf6 5.Nc3 Qh5 – The queen seeks activity on the kingside, eyeing e4 and h2.

Historical Notes
Although Aron Nimzowitsch (1886-1935) championed 1…Nc6, the specific line with 2.d4 d5 was explored in the early 20th century by Danish master Sverre Nielsen. Modern grandmasters such as Alexander Morozevich and Baadur Jobava have occasionally revived the variation to surprise opponents who expect the more popular 2…d6 or 2…e5 set-ups.
Practical Tips
- For White: Develop smoothly (Nc3, Be2 or Bb5, O-O). Do not rush pawn grabs; instead, gain time by harassing the black queen.
- For Black: Keep the queen flexible. If targeted, retreat to d6 or h5, where it still eyes central and kingside squares. Aim for …e5 or …e6 followed by …O-O-O to leverage the half-open d-file.
- Both sides should watch tactics on e4/e5 because the open e-file is the main arena of battle.
Interesting Facts & Anecdotes
- Aron Nimzowitsch once remarked that early queen moves are “healthy if they assist in conquering the centre,” a philosophy embodied perfectly in 3…Qxd5.
- In blitz, this defence scores significantly above average for Black in online databases, partly because its uncommonness induces hesitation in White.
- Engines evaluate the position after 4.Nf3 as roughly equal (≈0.20 for White on depth 40), highlighting the line’s soundness despite its rarity.
Conclusion
The move sequence 1.e4 Nc6 2.d4 d5 3.exd5 Qxd5 4.Nf3 offers a dynamic, off-beat battleground. It illustrates hyper-modern principles: early piece pressure, flexible pawn structures, and creative queen manoeuvres. Players seeking to leave mainstream opening theory without compromising objective soundness will find the Nimzowitsch Defence—and this line in particular—a fascinating weapon.
