Vienna Game: Heyde 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 Vienna Game: Heyde Variation

Play White's moves of the line from memory — 1. e4 e5 2. Nc3 Nf6 3. f4 d5 4. fxe5 Nxe4 5. Qf3 f5 6. d4 — and the trainer plays Black's replies; "Play the other side" turns it around.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Vienna Game: Heyde Variation page, or pick another opening in the opening trainer.
