Nimzo-Indian Defense: Leningrad Variation

Before the first move

The Leningrad Variation of the Nimzo-Indian is a sharp, provocative system where White immediately pins your knight on f6. While it looks like a standard Queen's Gambit, White's early bishop sortie creates a complex battle over the center and the kingside structure. You'll need to decide whether to challenge the pin or strike the center.

1. d4White

White plays d4, the most common alternative to e4. By occupying the center, White prepares to control the flow of the game. You'll need to respond carefully to prevent White from establishing a massive pawn center with a follow-up like e4.

1... Nf6Black · your move

Develop your knight to f6. This flexible move prevents White from immediately playing e4 and prepares to contest the center. It keeps your options open, allowing you to choose between several different defensive setups later.

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, aiming to trade a flank pawn for a central one. White could also try the London System or the Indian Pawn Push Variation, but c4 is the most ambitious attempt for an advantage.

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

Push your pawn to e6. This move solidifies your control over d5 and opens the diagonal for your king's bishop. It is a necessary step toward the Nimzo-Indian or Queen's Gambit Declined structures.

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, developing a piece and eyeing the e4 square. This is the main line, though White sometimes opts for the Catalan with g3 or the Seirawan Attack with Bg5 to avoid the specific tactical themes of the Nimzo-Indian.

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

3... Bb4Black · your move

Bring your bishop to b4 to pin the knight against the king. This is the defining move of the Nimzo-Indian Defense. You are neutralizing White's influence over the e4 square and preparing to trade if it helps your central control.

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. This creates an annoying pin on your knight. While the Rubinstein system with e3 or the Three Knights with Nf3 are more common, this move forces you to address the pressure on f6 immediately.

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)

Where you stand

The position is balanced but tense. Black usually continues with c5 to strike the center or h6 to test the bishop's intentions. White will aim to solidify the center and use the pin to hinder Black's coordination. Both sides must balance their development with the tactical threats created by the two active pins.

• c7-c5 Strike at the white center
• h7-h6 Challenge the g5 bishop immediately
• g1-f3 Develop and support the center
• e2-e3 Solidify d4 and open bishop
