Nimzo-Larsen Attack: Modern Variation trainer

Back to the opening, all openings to practise or my repertoire

Type a move and press Enter: e4, Nf3, O-O, or from and to squares like g1f3 (e7e8q to promote). The board is also played with the mouse.

Practise the Nimzo-Larsen Attack: Modern Variation

Play Black's moves of the line from memory — 1. b3 e5 2. Bb2 Nc6 3. c4 Nf6 — and the trainer plays White's replies; "Play the other side" turns it around.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Nimzo-Larsen Attack: Modern Variation page, or pick another opening in the opening trainer.
