Center Game: Kupreichik 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 Center Game: Kupreichik Variation

Play White's moves of the line from memory — 1. e4 e5 2. d4 exd4 3. Qxd4 Nc6 4. Qe3 Nf6 5. Nc3 Bb4 6. Bd2 O-O 7. O-O-O Re8 8. Bc4 d6 9. Nh3 — and the trainer plays Black's replies; "Play the other side" turns it around.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Center Game: Kupreichik Variation page, or pick another opening in the opening trainer.
