Sicilian Defense: Najdorf Variation, Opocensky 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: Najdorf Variation, Opocensky Variation

Play White's moves of the line from memory — 1. e4 c5 2. Nf3 Nf6 3. Nc3 d6 4. d4 cxd4 5. Nxd4 a6 6. Be2 e5 7. Nb3 Be6 8. Be3 — 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 Sicilian Defense: Najdorf Variation, Opocensky Variation page, or pick another opening in the opening trainer.
