Sicilian Defense: O'Kelly 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 Sicilian Defense: O'Kelly Variation

Play Black's moves of the line from memory — 1. e4 c5 2. Nf3 a6 — and the trainer plays White's replies; "Play the other side" turns it around.
