Queen's Gambit Declined: Normal 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 Queen's Gambit Declined: Normal Defense

Play Black's moves of the line from memory — 1. d4 d5 2. c4 e6 3. Nc3 Nf6 — and the trainer plays White's replies; "Play the other side" turns it around.
