Ruy Lopez: Classical Variation, Zukertort 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 Ruy Lopez: Classical Variation, Zukertort Gambit

Play White's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. O-O Bc5 5. c3 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 2 named lines that continue it, such as Ruy Lopez: Classical Defense, Benelux Variation, Ruy Lopez: Classical Variation, Modern Main Line.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Ruy Lopez: Classical Variation, Zukertort Gambit page, or pick another opening in the opening trainer.
