Old 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 Old Indian Defense

Play Black's moves of the line from memory — 1. d4 Nf6 2. c4 d6 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 13 named lines that continue it, such as Old Indian Defense: Czech Variation, with Nc3, King's Indian Defense: Orthodox Variation, Positional Defense, Old Indian Defense: Ukrainian Variation, Old Indian Defense: Czech Variation, with Nf3, Old Indian Defense: Normal Variation, Old Indian Defense: Janowski Variation, Old Indian Defense: Two Knights Variation, Old Indian Defense: Tartakower-Indian.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Old Indian Defense page, or pick another opening in the opening trainer.
