Ruy Lopez: Closed 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: Closed

Play White's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 48 named lines that continue it, such as Ruy Lopez: Marshall Attack, Ruy Lopez: Closed, Chigorin Defense, Ruy Lopez: Marshall Attack, Modern Variation, Ruy Lopez: Closed, Yates Variation, Ruy Lopez: Marshall Attack, Main Line, Ruy Lopez: Marshall Attack, Modern Main Line, Ruy Lopez: Closed, Anti-Marshall, Ruy Lopez: Closed, Pilnik Variation.

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