What is the best counter to the Nimzo-Indian Defense?

4. e3 and 4. Nf3 are generally the strongest counters to the Nimzo-Indian Defense.

4. Qc2 is also viable but provides less of a white advantage.

4. a3 (the Samisch Variation) is also sometimes seen but gives the advantage to black by allowing the black bishop to capture the knight and hurt white’s pawn structure, which conveys a long-term advantage.

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. a3 - a3 nimzo-Indian Defense

The Nimzo-Indian Defense is one of the most strategically deep in all of chess.

Let’s look at some other variations, which span from E20 to E59 in ECO Codes:

E20 – Romanishin Variation and 4.f3 Variation

1.d4 Nf6 2.c4 e6 3.Nc3

At this stage, the game could transition into a number of different openings, but if Black chooses to play 3…Bb4, we reach the Nimzo-Indian Defense.

The Romanishin Variation (3…Bb4 4.e3 0-0 5.Bd3 d5 6.a3 Bxc3+ 7.bxc3) prioritizes rapid development and delays Nf3.

The 4.f3 Variation (3…Bb4 4.f3) aims to achieve a big pawn center by preparing e4 without allowing Black to double White’s pawns.

E21 – Kasparov Variation

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Nf3

This variation emphasizes development and control of the center.

White avoids doubling the pawns while simultaneously preparing to strike back in the center with e4 or even expanding with a future d5.

Kasparov-Romanishin System

The Kasparov-Romanishin System of the Nimzo-Indian goes by the following line:

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.g3 O-O 5.Bg2 d5 6.Nf3 dxc4 7.O-O

It is a system that enables black to attain equality against Queen’s Gambit type openings.

Black has a 1-pawn advantage and works to maintain the advantage with careful positional play going forward in the line (given the c4 pawn is typically weak and hard to hang on to).

It was popular from around 1930 to 1960, with a small upturn in popularity when Kasparov used it in the 1980s.

Black will generally continue developing:

Nimzo-Indian Defense: Romanishin-Kasparov System - 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.g3 O-O 5.Bg2 d5 6.Nf3 dxc4 7.O-O
Nimzo-Indian Defense: Romanishin-Kasparov System – 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.g3 O-O 5.Bg2 d5 6.Nf3 dxc4 7.O-O

Black will generally try to build toward positions like this:

Nimzo-Indian Defense: Romanishin-Kasparov System - 1. Nf3 Nf6 2. c4 e6 3. d4 d5 4. g3 dxc4 5. Bg2 Bb4+ 6. Nc3 O-O 7. O-O Nc6 8. a3 Be7 9. Bf4 Nd5 10. Bd2 Nb6 11. Bf4 Na5 12. e4 Nb3 13. Rb1 c5 14. dxc5 Bxc5 15. Qxd8 Rxd8 16. Rbd1 Rxd1 17. Rxd1 Bd7 18. Ne5 Be8 19. Bf1 Na5 20. Bh3 Na4 21. Nxa4 Bxa4 22. Rc1 Rc8 23. Bg4 b5 24. Bh5
Nimzo-Indian Defense: Romanishin-Kasparov System – 1. Nf3 Nf6 2. c4 e6 3. d4 d5 4. g3 dxc4 5. Bg2 Bb4+ 6. Nc3 O-O 7. O-O Nc6 8. a3 Be7 9. Bf4 Nd5 10. Bd2 Nb6 11. Bf4 Na5 12. e4 Nb3 13. Rb1 c5 14. dxc5 Bxc5 15. Qxd8 Rxd8 16. Rbd1 Rxd1 17. Rxd1 Bd7 18. Ne5 Be8 19. Bf1 Na5 20. Bh3 Na4 21. Nxa4 Bxa4 22. Rc1 Rc8 23. Bg4 b5 24. Bh5

E22 – Spielmann Variation

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qb3

E23 – Spielmann Variation

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qb3 c5

This is a continuation of the Spielmann Variation where Black immediately challenges White’s center and seeks to exploit the somewhat exposed position of White’s queen.

E24 – Samisch Variation

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.a3

The Samisch Variation challenges Black’s bishop immediately.

The idea behind 4.a3 is to force Black to decide whether to exchange the bishop for the knight, thereby doubling White’s pawns, or retreat the bishop and concede the control over e4.

E25 – Samisch Variation Continued

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.a3 Bxc3+ 5.bxc3 c5

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.a3 Bxc3+ 5.bxc3 0-0 6.e3 c5

After 6.e3, Black immediately strikes at the center with 6…c5, contesting White’s central pawns and aiming for quick counterplay.

E30 – Leningrad Variation

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Bg5

In the Leningrad Variation, White seeks to pin the f6 knight and put pressure on Black’s position.

This move prepares e4, expanding in the center.

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Bg5 h6 5.Bh4 c5 6.d5 d6

E33 – Zurich/Milner-Barry Variation

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 Nc6

The position typically leads to a strategic battle with chances for both sides.

E36 – Classical Variation with 5.a3

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 d5 5.a3

After 4…d5, White plays 5.a3 to challenge Black’s bishop immediately.

This move is aimed to force Black to make a decision on whether to retreat or capture on c3.

E37 – Classical Variation with 6.Qxc3 Ne4

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 d5 5.a3 Bxc3+ 6.Qxc3 Ne4

After the exchange on c3, Black jumps into the center with 6…Ne4, eyeing the white queen and increasing central pressure.

It’s a direct and aggressive approach.

E38 – Classical Variation with 4…c5

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 c5

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 c5

After 4.e3, Black immediately challenges the center with 4…c5.

This line, often leading to the Hübner Variation, encourages complexity early in the game, with Black opting for active piece play and immediate central tension.

E42 – Rubinstein Variation, Romanishin-Psakhis Variation

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 c5 5.Ne2

Why is Bb4 played in the Nimzo-Indian Defense?

This move allows Black to exert control over the critical e4 square. It also sets up potential for doubling white’s pawns on the c-file if white decides to push e4 at some point and black exchanges on c3.

The doubled pawns can be targeted as weaknesses later in the game.

What are the main variations in the Nimzo-Indian Defense?

The Nimzo-Indian Defense has several main variations, each defined by White’s fourth move:

  • The Classical Variation (4.Qc2) – aims to avoid doubling pawns after black captures on c3.
  • The Rubinstein System (4.e3) – seeks to solidify the center, after which white may decide to develop the bishop to d3 or e2.
  • The Samisch Variation (4.a3) – challenges the bishop on b4 immediately, leading to a quick doubling of the c-pawns if black decides to capture.
  • The Kasparov Variation (4.Nf3) – a flexible move that allows White to avoid doubled pawns and develop naturally.

What are some famous games played in the Nimzo-Indian Defense?
