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, Endgame Variation

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 7. Nc3 Bxf3 8. gxf3 Qxd4 9. Qxd4 Nxd4 — and the trainer plays White's replies; "Play the other side" turns it around.
