Ruy Lopez: Berlin 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: Berlin Defense

The Berlin Defense (1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6) is the most solid answer to the Ruy Lopez. Play Black's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 36 named lines that continue it, such as Ruy Lopez: Berlin Defense, Anti-Berlin Variation, Ruy Lopez: Berlin Defense, Beverwijk Variation, Ruy Lopez: Berlin Defense, Improved Steinitz Defense, Ruy Lopez: Berlin Defense, Rio Gambit Accepted, Ruy Lopez: Classical Variation, Zukertort Gambit, Ruy Lopez: Berlin Defense, l'Hermet Variation, Ruy Lopez: Berlin Defense, l'Hermet Variation, Berlin Wall Defense, Ruy Lopez: Berlin Defense, Anti-Berlin Variation, Mortimer Variation.
