Bishop's Opening: Four Pawns 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 Bishop's Opening: Four Pawns Gambit

Play White's moves of the line from memory — 1. e4 e5 2. Bc4 Bc5 3. b4 Bxb4 4. f4 exf4 5. Nf3 Be7 6. d4 Bh4+ 7. g3 fxg3 8. O-O gxh2+ 9. Kh1 — and the trainer plays Black's replies; "Play the other side" turns it around.
