Sicilian Defense: Open 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 Sicilian Defense: Open

Play Black's moves of the line from memory — 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 29 named lines that continue it, such as Sicilian Defense: Lasker-Pelikan Variation, Sicilian Defense: Lasker-Pelikan Variation, Schlechter Variation, Sicilian Defense: Lasker-Pelikan Variation, Sveshnikov Variation, Sicilian Defense: Lasker-Pelikan Variation, Sveshnikov Variation, Chelyabinsk Variation, Sicilian Defense: Lasker-Pelikan Variation, Retreat Variation, Sicilian Defense: Sozin Attack, Leonhardt Variation, Sicilian Defense: Lasker-Pelikan Variation, Exchange Variation, Sicilian Defense: Lasker-Pelikan Variation, Sveshnikov Variation, Novosibirsk Variation.
