Nimzo-Indian: 4.e3 c5 5.Bd3 Nc6 6.Ne2
Nimzo-Indian: 4.e3 c5 5.Bd3 Nc6 6.Ne2
Definition
This sequence arises from the Rubinstein System of the Nimzo-Indian Defence: 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 c5 5.Bd3 Nc6 6.Ne2. By playing 5.Bd3 followed by 6.Ne2, White avoids the usual pin on the c3-knight, keeps the option of recapturing on c4 with the bishop, and prepares the central break e3–e4. The line is sometimes catalogued as the “Bd3–Ne2 Variation” or “Classical Rubinstein with …Nc6.”
Move Order and Key Ideas
- 4.e3 — The Rubinstein move, solidly protecting d4 and freeing the dark-square bishop.
- 4…c5 — Black strikes at the centre immediately, aiming for isolated-queen-pawn or hanging-pawn structures.
- 5.Bd3 — A flexible square for the bishop; it eyes h7 and supports an eventual e4.
- 5…Nc6 — Increases pressure on d4 and prepares …d5 or …Bxc3 followed by …d5.
- 6.Ne2 — Unpins the c3-knight, reinforces d4, and keeps the f-pawn free for f2–f3 or f2–f4 plans.
Strategic Themes
- Central Tension: The pawn standoff on d4–c5 shapes middlegame play. White often chooses between maintaining the centre with b2–b3 or breaking with d4-d5.
- Bishop Pair vs. Structure: Black can exchange on c3, doubling White’s pawns but granting White the bishop pair. With Bd3 already on the board, recapturing with the bishop sometimes avoids doubled pawns altogether.
- Flexible King Placement for White: Because the g1-knight is on e2, White can castle kingside or—after f2–f3 and Kf2—opt for a fashionable “artificial long castle” setup used in modern praxis.
- Black’s Counterplay: Common plans involve …d5 in one move (if possible), minority attacks with …b5-b4, or piece pressure on c4 after the thematic …d5 dxc5 …Bxc3+ idea.
Typical Plans for Each Side
- White
- Advance e3–e4 after adequate preparation (Qe2, 0-0, Rd1).
- Expand on the kingside with f2–f4 and g2–g4 in aggressive setups.
- Maintain the two bishops and aim for long-term endgame pressure.
- Black
- Break with …d5 to liquidate the centre, often accepting an isolated queen’s pawn position.
- Target c4 and d4 with pieces; the natural square for the light-square bishop is either …b7 after …b6 or …a6 following …cxd4.
- Play for queenside majority: …b6, …Ba6, and …cxd4 create queenside pawn targets.
Historical Background & Notable Games
The move 6.Ne2 was popularized in the 1960s by Soviet grandmasters such as Boris Spassky and Tigran Petrosian, who valued its solidity and flexibility. It has since appeared in elite practice; for instance:
- Magnus Carlsen – Levon Aronian, Bilbao Masters 2012 (Carlsen employed 6.Ne2, steered the game into a kingside attack, and won a memorable rook endgame.)
- Fabiano Caruana – Ding Liren, Candidates 2018 (An instructive draw showing Black’s equalizing plan with …d5 and …cxd4.)

Interesting Facts & Anecdotes
- Because the king knight heads for e2 instead of f3, some commentators jokingly call the setup “the Hipster Knight”—it refuses the mainstream f3 square.
- In database statistics, 6.Ne2 scores only a few percentage points less than the main line 6.Nf3, yet it is played roughly ten times less often—an attractive ratio for surprise-minded theoreticians.
- Computer engines initially undervalued 6.Ne2, but AlphaZero’s self-play games revived interest, showing dynamic potential after the pawn sacrifice d4-d5 in several lines.
Summary
The sequence 4.e3 c5 5.Bd3 Nc6 6.Ne2 offers White a robust and less-explored alternative within the Nimzo-Indian. It keeps options fluid, avoids early structural commitments, and produces rich middlegame play. Black, in turn, obtains immediate queenside counterplay and rapid piece development. For tournament players who like the strategic depth of the Nimzo-Indian without drowning in forcing theory, this line remains an excellent practical weapon.
