Ruy Lopez: Steinitz Defense, Nimzowitsch Attack 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, Nimzowitsch Attack

Play White's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Bb5 d6 4. d4 Bd7 5. Nc3 Nf6 6. Bxc6 — and the trainer plays Black's replies; "Play the other side" turns it around.
