Queen's Gambit Declined 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

Play White's moves of the line from memory — 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. Bg5 Nbd7 6. e3 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 5 named lines that continue it, such as Queen's Gambit Declined: Cambridge Springs Defense, Queen's Gambit Declined: Cambridge Springs Defense, Bogoljubow Variation, Queen's Gambit Declined: Cambridge Springs Defense, Yugoslav Variation, Queen's Gambit Declined: Cambridge Springs Defense, Rubinstein Variation.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Queen's Gambit Declined page, or pick another opening in the opening trainer.
