Modern Defense: Standard Line 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 Modern Defense: Standard Line

Play White's moves of the line from memory — 1. e4 g6 2. d4 Bg7 3. Nc3 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 17 named lines that continue it, such as Modern Defense: Standard Defense, Modern Defense: Two Knights Variation, Modern Defense: Pseudo-Austrian Attack, Modern Defense: Modern Pterodactyl, Modern Defense: Two Knights Variation, Suttles Variation, Modern Defense: Mongredien Defense, with Nc3, Pterodactyl Defense: Eastern, Anhanguera, Pterodactyl Defense: Eastern, Rhamphorhynchus.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Modern Defense: Standard Line page, or pick another opening in the opening trainer.
