Queen's Gambit Declined: Exchange Variation, Positional 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 Queen's Gambit Declined: Exchange Variation, Positional Variation

Play White's moves of the line from memory — 1. d4 Nf6 2. c4 e6 3. Nc3 d5 4. cxd5 exd5 5. Bg5 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 7 named lines that continue it, such as Queen's Gambit Declined: Exchange Variation, Reshevsky Variation, Queen's Gambit Declined: Exchange Variation, Carlsen Variation, Queen's Gambit Declined: Exchange Variation, Chameleon Variation.

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