Sicilian Defense: Hyperaccelerated Pterodactyl 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 Sicilian Defense: Hyperaccelerated Pterodactyl

Play Black's moves of the line from memory — 1. e4 c5 2. Nf3 g6 3. d4 Bg7 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 8 named lines that continue it, such as Pterodactyl Defense: Western, Rhamphorhynchus, Pterodactyl Defense: Sicilian, Rhamphorhynchus, Pterodactyl Defense: Sicilian, Pteranodon, Sicilian Defense: Hyperaccelerated Pterodactyl, Exchange Variation, Modern Defense: Pterodactyl Variation, Pterodactyl Defense: Sicilian, Anhanguera, Pterodactyl Defense: Sicilian, Unpin, Pterodactyl Defense: Sicilian, Benoni Gambit.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Sicilian Defense: Hyperaccelerated Pterodactyl page, or pick another opening in the opening trainer.
