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: Alapin Variation, Barmen Defense, Central Exchange

Play Black's moves of the line from memory — 1. e4 c5 2. c3 d5 3. exd5 Qxd5 4. d4 cxd4 5. cxd4 Nc6 6. Nf3 Bg4 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 1 named line that continue it, such as Sicilian Defense: Alapin Variation, Barmen Defense, Endgame Variation.

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