Center Game: Ross Gambit 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: Ross Gambit

Play White's moves of the line from memory — 1. e4 e5 2. d4 exd4 3. Bd3 — 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: Ross Gambit page, or pick another opening in the opening trainer.
