Ruy Lopez: Berlin Defense, Anti-Berlin Variation, Anderssen Variation 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: Berlin Defense, Anti-Berlin Variation, Anderssen Variation

Play White's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. d3 d6 5. Bxc6+ — and the trainer plays Black's replies; "Play the other side" turns it around.
