Queen's Gambit Declined: Queen's Knight 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: Queen's Knight Variation

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

"Drill all" adds the 89 named lines that continue it, such as Queen's Gambit Declined: Normal Defense, Queen's Gambit Declined: Modern Variation, Semi-Slav Defense: Accelerated Move Order, Queen's Gambit Declined, Tarrasch Defense, Queen's Gambit Declined: Harrwitz Attack, Tarrasch Defense: Symmetrical Variation, Semi-Slav Defense: Marshall Gambit.
