Dutch Defense: Stonewall Variation, 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 Dutch Defense: Stonewall Variation, Modern Variation

Play Black's moves of the line from memory — 1. d4 f5 2. c4 e6 3. Nf3 Nf6 4. g3 c6 5. Bg2 d5 6. O-O Bd6 — 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 Dutch Defense: Stonewall Variation, Modern Variation page, or pick another opening in the opening trainer.
