Trompowsky Attack: Raptor 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 Trompowsky Attack: Raptor Variation

Play White's moves of the line from memory — 1. d4 Nf6 2. Bg5 Ne4 3. h4 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 1 named line that continue it, such as Trompowsky Attack: Raptor Variation, Hergert Gambit.

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