French Defense: St. George Defense, St. George Gambit 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: St. George Defense, St. George Gambit

Play Black's moves of the line from memory — 1. e4 e6 2. d4 a6 3. c4 b5 4. cxb5 axb5 — and the trainer plays White'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: St. George Defense, St. George Gambit page, or pick another opening in the opening trainer.
