Nimzo-Indian Defense 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-Indian Defense

The Nimzo-Indian Defense (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4) is considered one of the best defences to 1.d4. Play Black's moves of the line from memory — 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 96 named lines that continue it, such as Nimzo-Indian Defense: Classical Variation, Nimzo-Indian Defense: Three Knights Variation, Nimzo-Indian Defense: Rubinstein System, Nimzo-Indian Defense: Leningrad Variation, Nimzo-Indian Defense: Sämisch Variation, Nimzo-Indian Defense: Normal Variation, Nimzo-Indian Defense: Normal Variation, Ragozin Variation, Nimzo-Indian Defense: Kmoch Variation.
