Sicilian Defense: Dragon Variation, Classical Variation, Battery 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: Dragon Variation, Classical Variation, Battery Variation

Play White's moves of the line from memory — 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be2 Bg7 7. O-O O-O 8. Be3 Nc6 9. Qd2 — and the trainer plays Black's replies; "Play the other side" turns it around.
