Philidor Defense: Lion Variation, Sozin 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 Philidor Defense: Lion Variation, Sozin Variation

Play Black's moves of the line from memory — 1. e4 d6 2. d4 Nf6 3. Nc3 e5 4. Nf3 Nbd7 5. Bc4 Be7 6. O-O O-O 7. Qe2 c6 8. a4 exd4 — and the trainer plays White's replies; "Play the other side" turns it around.
