Nimzo-Indian Defense: Normal Variation, Ragozin Variation

Before the first move

The Nimzo-Indian Defense is one of Black's most reliable responses to the Queen's Pawn Opening. By pinning the knight on c3, you fight for control of the e4-square without immediately committing your central pawns. This specific Ragozin Variation blends the Nimzo's pressure with a solid classical center.

1. d4White

White starts with d4, the second most popular opening move. It leads to more closed, strategic games compared to the open lines of e4. You will need to decide how to contest the center—common replies include Nf6 and d5.

1... Nf6Black · your move

Develop your knight to f6. This flexible move prevents White from immediately playing e4 and keeps your options open for several different defensive setups against the d-pawn.

Other paths here: Na6 (Australian Defense) · g5 (Borg Defense: Borg Gambit) · b6 (English Defense) · e5 (Englund Gambit)

2. c4White

White plays c4, increasing their grip on the center and inviting a transposition into many main-line systems. Other tries like f4 (Canard) or g3 (Catalan style) are possible, but c4 is the most ambitious and standard continuation.

Other paths here: f4 (Canard Opening) · g4 (Indian Defense: Gibbins-Weidenhagen Gambit) · e4 (Indian Defense: Omega Gambit) · d5 (Indian Defense: Pawn Push Variation)

2... e6Black · your move

Move your pawn to e6. This solidifies your control of d5 and opens the diagonal for your king's bishop, preparing for a quick development of your kingside.

Other paths here: g5 (Indian Defense: Medusa Gambit) · b5 (Indian Defense: Pyrenees Gambit) · a6 (Indian: 2.c4 a6) · Nc6 (Mexican Defense)

3. Nc3White

White plays Nc3, the most direct way to challenge for the center. This move invites the Nimzo-Indian Defense. White could also choose g3 to enter a Catalan or Nf3 to keep the options more fluid and avoid the upcoming pin.

Other paths here: g3 (Catalan Opening) · Qb3 (Indian Defense) · g4 (Indian Defense: Devin Gambit) · Bg5 (Indian Defense: Seirawan Attack)

3... Bb4Black · your move

Slide your bishop to b4 to pin the knight against the king. This is the defining move of the Nimzo-Indian, making it difficult for White to easily push e4.

Other paths here: b6 (Queen's Pawn: Neo-Indian, 3...b6) · c5 (Queen's Pawn: Neo-Indian, 3...c5) · d5 (Queen's Gambit Declined: Exchange Variation)

4. e3White

White chooses the Rubinstein System with e3, a very solid and respected approach. White prioritizes development and safety over immediate aggression. Sharper alternatives include the Kmoch Variation with f3 or the Mikenas Attack with Qd3.

Other paths here: f3 (Nimzo-Indian Defense: Kmoch Variation) · Qd3 (Nimzo-Indian Defense: Mikenas Attack) · g3 (Nimzo-Indian Defense: Romanishin Variation) · Bd2 (Nimzo-Indian: 4.Bd2)

4... O-OBlack · your move

Castle your king to safety. Getting your king out of the center is a priority before the central tension is resolved and the files potentially open up.

Other paths here: Nc6 (Nimzo-Indian Defense: Rubinstein System, Taimanov Variation) · c5 (Nimzo-Indian Defense: Rubinstein System) · b6 (Nimzo-Indian Defense: St. Petersburg Variation) · d5 (Keres Variation, Nimzo-Indian)

5. Nf3White

White plays Nf3, continuing natural development. This move is the most common, though White sometimes tries Ne2 (the Reshevsky Variation) to avoid doubled pawns if you capture on c3, or the aggressive a3 to put the question to your bishop.

Other paths here: Ne2 (Nimzo-Indian Defense: Reshevsky Variation) · Bd3 (Nimzo-Indian Defense: Normal Variation) · a3 (Nimzo-Indian Defense: Sämisch Variation)

5... d5Black · your move

Push your pawn to d5. This move strikes at the center and transitions the game into the Ragozin Variation, creating a solid pawn structure while your bishop remains active on b4.

Other paths here: b6 (Nimzo-Indian: 4.e3 O-O 5.Nf3 b6) · c5 (Nimzo-Indian: 4.e3 O-O 5.Nf3 c5) · Ne4 (Nimzo-Indian: 4.e3 O-O 5.Nf3 Ne4)

Where you stand

The position is balanced and rich with strategic themes. White will likely develop the light-squared bishop to d3 and seek to castle, while Black often looks to play c5 to challenge the center or b6 to develop the queen's bishop. Both sides must carefully manage the tension between the c4 and d5 pawns.

• c1-d2 Develop the bishop to unpin the knight
• f1-d3 Place the bishop on an active diagonal
• c8-a6 Fianchetto or develop the bishop to a6
• c7-c5 Challenge the center with the c-pawn
