Ruy Lopez: Morphy Defense, Modern Steinitz Defense 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: Morphy Defense, Modern Steinitz Defense

Play Black's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 d6 5. Bxc6+ bxc6 6. d4 f6 — and the trainer plays White's replies; "Play the other side" turns it around.

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