Ruy Lopez: 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: Steinitz Defense

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

"Drill all" adds the 4 named lines that continue it, such as Ruy Lopez: Steinitz Defense, Nimzowitsch Attack, Ruy Lopez: Steinitz Defense, Center Gambit, Ruy Lopez: Berlin Defense, Tarrasch Trap, Ruy Lopez: Steinitz Defense, Semi-Duras Variation.

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