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

The Catalan Opening (1.d4 Nf6 2.c4 e6 3.g3, usually followed by ...d5 and Bg2) combines the Queen's Gambit with a kingside fianchetto. Play White's moves of the line from memory — 1. d4 Nf6 2. c4 e6 3. g3 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 32 named lines that continue it, such as Catalan Opening: Closed, Catalan Opening: Open Defense, Bogo-Indian Defense: Retreat Variation, Benoni Defense: Fianchetto Variation, Catalan Opening: Open Defense, Classical Line, Catalan Opening: Closed, Botvinnik Variation, Benoni Defense: Fianchetto Variation, Hastings Defense, Main Line, Catalan Opening: Open Defense, Modern Sharp 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.
