Queen's Gambit Accepted: Old 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 Accepted: Old Variation

The Old Variation is 1.d4 d5 2.c4 dxc4 3.e3, a quiet way for White to meet the Queen's Gambit Accepted. Play White's moves of the line from memory — 1. d4 d5 2. c4 dxc4 3. 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 Accepted: Old Variation, Christensen Gambit, Queen's Gambit Accepted: Old Variation, Billinger Gambit, Queen's Gambit Accepted: Classical Defense, Russian Gambit, Queen's Gambit Accepted: Old Variation, Korchnoi Gambit, Queen's Gambit Accepted: Old Variation, Novikov Gambit.

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