Four Knights Game: Halloween Gambit, Oldtimer 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 Four Knights Game: Halloween Gambit, Oldtimer Variation

Play Black's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Nxe5 Nxe5 5. d4 Ng6 6. e5 Ng8 7. Bc4 Bb4 8. Qf3 f5 — and the trainer plays White's replies; "Play the other side" turns it around.
