Nimzowitsch Defence: 2.Nf3 d6 3.d4 Nf6 4.Nc3 g6
Definition
The Nimzowitsch Defence is a hyper-modern reply to 1. e4 that begins with 1…Nc6. After the “main track” 2. Nf3 d6 3. d4 Nf6 4. Nc3 g6, Black heads for a set-up that resembles the Pirc Defence while retaining the flexibility of the …Nc6 knight. The complete move-order is:
1. e4 Nc6 2. Nf3 d6 3. d4 Nf6 4. Nc3 g6
How it is Used in Play
- Hyper-modern philosophy: Black delays occupation of the centre with pawns, instead attacking it with minor pieces (…Nf6, …Bg7) and aiming for pawn breaks such as …e5 or …c5.
- Transpositional weapon: Depending on White’s replies, the game can transpose to Pirc/Modern, Chigorin-style Queen’s Pawn openings, or independent Nimzowitsch lines.
- Surprise value: Because most 1…Nc6 specialists are rare at the top level, many e4 players are less booked-up than against the mainline 1…e5 or 1…c5 defences.
- Typical plans for Black:
- Fianchetto the king’s bishop to g7, castle short, and strike in the centre with …e5 or …d5.
- Place rooks on e8 and c8 to support the pawn breaks.
- Use the c6-knight to pressure d4 or jump to b4/d4/f4 depending on circumstances.
Strategic Themes
- Flexible Centre: Black keeps both central pawns (d7 and e7) uncommitted, making it hard for White to decide on an optimal set-up.
- Minor-piece Pressure: The fianchettoed bishop on g7 eyes the e5 and d4 squares; combined with the c6-knight it can create double attacks on d4.
- Delayed Conflict: Unlike open games starting with 1…e5, the tension often remains for ten or more moves, leading to manoeuvring play reminiscent of King’s Indian structures.
Historical Background
The line is named after Aron Nimzowitsch (1886-1935), one of the seminal thinkers of the hyper-modern school and author of the classic My System. He experimented with 1…Nc6 as early as 1910, though the fianchetto continuation became popular much later. Modern proponents include Grandmasters Sergei Tiviakov (who has an enormous score with 1…Nc6), Vadim Zvjaginsev, and occasional use by Magnus Carlsen in online blitz.
Illustrative Example
An abbreviated game highlighting the main ideas:
Key moments:
- Move 14 …e5! – Black finally challenges the centre after harmonious development.
- Complex middlegame with opposite-sided pawn majorities shows the rich strategic possibilities.

Sample Tactical Motif
A common trap occurs if White plays 5. Be3? too early:
1. e4 Nc6 2. Nf3 d6 3. d4 Nf6 4. Nc3 g6 5. Be3? Bg7 6. Qd2 Ng4! – Black threatens 7…Nxe3, doubling White’s e-pawns, or 7…Nxe3 8. Qxe3 Bh6, regaining a tempo.
Interesting Facts & Anecdotes
- Aron Nimzowitsch allegedly coined the joking motto “First restrain, then blockade, finally destroy,” which appears in embryo in this opening’s flexible pawns.
- GM Sergei Tiviakov once went 45 consecutive games without defeat using 1…Nc6 in classical play (2005-2006).
- Because of its chameleon nature, some database statistics count many 1…Nc6 games under the Pirc ECO codes (B07-B09), masking its actual popularity.
Theoretical Status
Modern engines give the line a healthily balanced evaluation (≈0.20) if Black knows the ideas. White’s most critical tries involve an early f2-f4 or Be2 followed by 0-0 and d4-d5.
