French Defense: Steinitz Variation, Boleslavsky 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 French Defense: Steinitz Variation, Boleslavsky Variation

Play White's moves of the line from memory — 1. e4 e6 2. d4 d5 3. Nc3 Nf6 4. e5 Nfd7 5. f4 c5 6. Nf3 Nc6 7. 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 French Defense: Steinitz Variation, Boleslavsky Variation page, or pick another opening in the opening trainer.
