Catalan Opening
The Catalan Opening is a solid opening where White chooses to fianchetto their light-square bishop in a Queen's Gambit–esque position. The Catalan can be used to reach a sensible position against nearly all setups by Black.

Strategic guide
Plans and motifs
- White slowly mounts queenside pressure and hopes to break through on that side at a later stage of the game.
- White may intentionally gambit their c4 pawn to gain an open diagonal for the light-square bishop.
- Note that in the QGA, White usually recaptures on c4 with the light-square bishop, but this is not possible in the Catalan.
- Instead, White can choose to recapture the pawn with a knight, with Nf3-Ne5 and/or Nbd2.
