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, Zollner Gambit

Play White's moves of the line from memory — 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6 5. Be3 Bg7 6. Be2 Nf6 7. Nc3 O-O 8. O-O d6 9. f4 Qb6 10. e5 — and the trainer plays Black's replies; "Play the other side" turns it around.
