Pterodactyl Defense: Austrian, Pteranodon 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 Pterodactyl Defense: Austrian, Pteranodon

Play Black's moves of the line from memory — 1. e4 g6 2. d4 Bg7 3. f4 c5 4. c3 Qa5 — 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 Pterodactyl Defense: Austrian, Pteranodon page, or pick another opening in the opening trainer.
