Catalan Opening 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 Catalan Opening

Play Black's moves of the line from memory — 1. d4 Nf6 2. c4 e6 3. g3 d5 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 17 named lines that continue it, such as Catalan Opening: Closed, Catalan Opening: Open Defense, Catalan Opening: Open Defense, Classical Line, Catalan Opening: Closed, Botvinnik Variation, Catalan Opening: Open Defense, Modern Sharp Variation, Catalan Opening: Closed, Sokolsky Variation, Catalan Opening: Open Defense, Alekhine Variation.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Catalan Opening page, or pick another opening in the opening trainer.
