Philidor Defense: Berger 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: Berger Variation

Play White's moves of the line from memory — 1. e4 e5 2. Nf3 d6 3. d4 exd4 4. Nxd4 Nf6 5. Nc3 Be7 6. Be2 O-O 7. O-O c5 8. Nf3 Nc6 9. Bg5 Be6 10. Re1 — and the trainer plays Black's replies; "Play the other side" turns it around.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Philidor Defense: Berger Variation page, or pick another opening in the opening trainer.
