Ruy Lopez: Morphy Defense, Steinitz Deferred 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, Steinitz Deferred

Play Black's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O d6 6. Bxc6+ bxc6 7. d4 Nxe4 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 1 named line that continue it, such as Ruy Lopez: Steinitz Defense Deferred, Boleslavsky Variation.

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