Nimzowitsch Variation

1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Ba6 5.b3

This line reinforces the c4 pawn and sets up queenside development with Bb2. Black's ...Ba6 puts immediate pressure on c4 and can lead to early structural decisions and subtle positional play.

Typical Plans

White: Bb2 and 0-0

Bb2, Bg2, 0-0

White builds a double-fianchetto structure and aims for long-term central control.

Black: Exchange and Breaks

...Bb4+ and ...d5

Black can trade pieces and challenge the center with a timely ...d5 or ...c5.

Structure Matters

c-pawn tension

Both sides must watch how the c4 pawn is supported and attacked, as it often defines the game.

Queenside Structure Focus

This variation is a great fit if you like slow pressure and clear pawn-structure goals.
