The Catalan Opening is a chess opening where White plays d4 and c4 and fianchettoes the white bishop on g2. A common opening sequence is 1.d4 Nf6 2.c4 e6 3.g3, although various other openings can transpose into the Catalan. The Encyclopaedia of Chess Openings (ECO) lists codes E01–E09 for lines with 1.d4 Nf6 2.c4 e6 3.g3 d5 4.Bg2; other lines are part of E00.
In the Catalan, White adopts a combination of the Queen's Gambit and Réti Opening. White combines the space-gaining moves d4 and c4 with g3, preparing to fianchetto the king's bishop. This places pressure mainly on the queenside while hoping to keep the white king safe in the long-term. The c4-pawn can become vulnerable, however, and White might have to sacrifice a pawn.
Black has two main approaches to play against the Catalan: in the Open Catalan Black plays ...dxc4 and can either try to hold on to the pawn with ...b5 or give it back for extra time to free their game. In the Closed Catalan, Black does not capture on c4; their game can be somewhat cramped for a while, but is quite solid. Additionally, Black has ways to avoid the Catalan.
The Catalan has had proponents at the highest level in chess, with Vladimir Kramnik, Viswanathan Anand and Magnus Carlsen all employing the opening in their World Chess Championship title games. A number of other grandmasters have successfully played the Catalan, including Fabiano Caruana, Daniil Dubov, Anish Giri and Ding Liren.
