French Defense: Winawer Variation, Positional 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: Winawer Variation, Positional Variation

Play White's moves of the line from memory — 1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. e5 c5 5. a3 Bxc3+ 6. bxc3 Ne7 7. Nf3 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 2 named lines that continue it.

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