Sicilian 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 Sicilian Defense

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

"Drill all" adds the 294 named lines that continue it, such as Sicilian Defense: Old Sicilian, Sicilian Defense: Modern Variations, Sicilian Defense: Open, Sicilian Defense: French Variation, Sicilian Defense: Modern Variations, Main Line, Sicilian Defense: French Variation, Open, Sicilian Defense: Najdorf Variation, Sicilian Defense: Nyezhmetdinov-Rossolimo Attack.

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