Nimzo-Indian Defense: Sämisch Variation

Before the first move

The Sämisch Variation of the Nimzo-Indian is a battle of structure versus activity. White accepts doubled pawns on the c-file to gain a powerful central mass and the pair of bishops. As Black, you aim to exploit those static weaknesses, while as White, you seek to use your extra space and central control to launch a crushing attack.

1. d4White

White plays d4, the most common alternative to e4. By occupying the center, White prepares to develop the queenside pieces. You will have to decide whether to meet this with a direct challenge like d5 or a more flexible response like Nf6.

1... Nf6Black · your move

Develop your knight to f6. This is the most flexible response to d4, preventing White from immediately playing e4 and keeping your options open for several different defensive setups. It prepares for a quick kingside development.

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

2. c4White

White plays c4, expanding in the center and preparing to develop the queen's knight. You now have several paths: the solid e6 leading to the Nimzo or Queen's Gambit, or the sharp g6 leading to the King's Indian or Grünfeld.

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 solidifies your control of the center and opens a path for your dark-squared bishop. It is a necessary step toward the Nimzo-Indian or the Queen's Gambit Declined, prioritizing safe development.

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, intending to seize the center with e4. This is the critical moment where you must decide how to react. You can play d5 for a Queen's Gambit, or the signature Nimzo-Indian move Bb4, which pins the knight.

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. This pin on the c3-knight is the defining move of the Nimzo-Indian Defense. You are preventing White from playing e4 and preparing to potentially trade your bishop to damage White's pawn structure.

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. a3White

White plays a3, immediately questioning your bishop. This is the sharpest way to meet the Nimzo-Indian. While you could retreat to a5, the most common and principled response is to take the knight and create structural weaknesses for White.

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... Bxc3+Black · your move

Capture the knight on c3. By giving up your bishop, you create doubled pawns for White. This trade defines the strategic landscape: you have a better pawn structure, while White has the advantage of two bishops and a strong center.

Other paths here: Ba5 (Sämisch Variation)

5. bxc3White

White plays bxc3, accepting the doubled pawns. The c-file is now somewhat blocked, and the c3-pawn is a potential target for you. White's plan will involve pushing the center pawns to create an attack, while you must counter-attack.

5... c5Black · your move

Push your pawn to c5. This is a thematic strike against White's center. You are trying to fix the doubled pawns and create a target on c4. It also opens the c-file for your future rook or queen pressure.

Other paths here: b6 (Nimzo-Indian: Saemisch, 5...b6) · d5 (Nimzo-Indian: Saemisch, 5...d5) · O-O (Nimzo-Indian Defense: Sämisch Variation)

6. e3White

White plays e3, reinforcing the center and preparing to develop the light-squared bishop. This is a solid, positional approach. White could also try the more aggressive f3, aiming to build a massive pawn center with e4 in the near future.

Other paths here: f3 (Nimzo-Indian: Saemisch, 5...c5 6.f3)

Where you stand

The position is strategically complex. White will try to use the bishop pair and a central pawn push (f3 and e4) to create an attack. Black's plan is to blockade the center, perhaps with d6 and e5, and target White's weak c4-pawn. The game often becomes a race between White's kingside pressure and Black's queenside counterplay.

• c5-d4 Trade on d4 to open the c-file
• f6-e4 Knight pressures the e4 and d5 squares
• f1-d3 Develop bishop to its most active diagonal
• f2-f3 Prepare the e4 central pawn push
