Queen's Pawn Game: Stonewall Attack 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 Queen's Pawn Game: Stonewall Attack

The Stonewall Attack is a system for White rather than a set of lines: pawns on d4, e3, c3 and f4, the bishop on d3 and the knight on d2. Play White's moves of the line from memory — 1. d4 d5 2. e3 Nf6 3. Bd3 — 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 Queen's Pawn Game: Stonewall Attack page, or pick another opening in the opening trainer.
