Modern Defense: Anti-Modern 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: Anti-Modern

Play White's moves of the line from memory — 1. e4 g6 2. d4 Bg7 3. Nc3 c6 4. Bc4 d6 5. Qe2 — and the trainer plays Black's replies; "Play the other side" turns it around.

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