Nimzo-Indian Defense: Leningrad Variation, Benoni Defense

Before the first move

The Leningrad Variation of the Nimzo-Indian is a sharp, provocative system where White pins your knight early to create tension. By combining Nimzo-Indian piece pressure with Benoni-style pawn structures, you invite a complex battle for the center where every tempo counts.

1. d4White

White starts with d4, the most common alternative to the king's pawn opening. It leads to strategic, closed positions where understanding pawn structures is more important than raw calculation.

1... Nf6Black · your move

Develop your knight to f6. This flexible move controls the e4 and d5 squares, preventing White from immediately grabbing the full center with a second pawn move.

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

2. c4White

White plays c4, the signature move of the Queen's Gambit family. White could also try the London System with Bf4 or the Trompowsky with Bg5, but c4 is the most ambitious challenge.

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 over d5 and opens the diagonal for your dark-squared bishop to enter the game and challenge White's knight.

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 aggressive development. By not choosing the Catalan with g3 or the Anti-Nimzo a3, White allows you to pin this knight and fight for the initiative immediately.

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

3... Bb4Black · your move

Develop your bishop to b4 and pin White's knight to the king. This is the defining move of the Nimzo-Indian, neutralizing White's influence over the e4 square.

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. Bg5White

White plays Bg5, the Leningrad Variation. It is more aggressive than the main-line 4.e3 or the 4.Qc2 Classical Variation. White ignores the pin on c3 to create their own threats against your king's knight.

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... h6Black · your move

Push your pawn to h6 to put the question to the bishop. You are forcing White to decide whether to trade their bishop for your knight or retreat and maintain the tension.

Other paths here: c5 (Nimzo-Indian: Leningrad, 4...c5) · O-O (Nimzo-Indian: Leningrad, 4...O-O)

5. Bh4White

White plays Bh4, maintaining the pin. The alternative is to capture on f6, which simplifies the position. By retreating, White keeps the game complex and dares you to expand further on the kingside.

Other paths here: Bxf6 (Nimzo-Indian: Leningrad, 4...h6 5.Bxf6)

5... c5Black · your move

Strike at the center with c5. You are challenging White's d4-pawn and creating a Benoni-style structure that opens lines for your queen and creates dynamic counterplay.

6. d5White

White plays d5, the most ambitious reply. Instead of defending with e3, White gains space and restricts your pieces. This leads to very sharp play where the center becomes a locked battleground.

6... d6Black · your move

Move your pawn to d6. This move stops White's d-pawn from advancing further and prepares to develop your queenside pieces while maintaining a solid defensive wall.

Other paths here: b5 (Nimzo-Indian Defense: Leningrad Variation, Averbakh Gambit) · Bxc3+ (Nimzo-Indian: Leningrad, 6.d5 Bxc3+) · exd5 (Nimzo-Indian: Leningrad, 6.d5 exd5)

Where you stand

The position has reached a Benoni-style structure with a heavy pin on f6. White enjoys a space advantage and kingside pressure, while Black has a solid position and clear plans to undermine the center with a7-a6 and b7-b5. Both sides must balance their development with the tactical threats created by the active bishops.

• b8-d7 Develop the knight to support the center
• e2-e3 Solidify the center and open the bishop
• a7-b5 Expand on the queenside for counterplay
• f1-d3 Develop the bishop to an active square
