English Defense: Poli 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 English Defense: Poli Gambit

Play Black's moves of the line from memory — 1. d4 e6 2. c4 b6 3. e4 Bb7 4. f3 f5 5. exf5 Nh6 — 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 English Defense: Poli Gambit page, or pick another opening in the opening trainer.
