Every page is also served as markdown at its URL plus .md. The Catalan setup is a White formation with pawns on d4 and c4 and a fianchettoed bishop on g2. There are two main branches. The Catalan setup is a White formation with pawns on d4 and c4 and a fianchettoed bishop on g2, putting long-term pressure on Black's center and the queenside along the long diagonal. White plays d4, c4 and g3, then Bg2, and keeps the [bishop](https://georgelichess.com/glossary/bishop.md) pointed at the d5 pawn and the b7 [square](https://georgelichess.com/glossary/square.md). The bishop is the star: even after trades it stays a strong piece, because Black's queenside is where it hits. Many Catalan games are played around the principle of using that bishop to pressure c6, b7 and the rook on a8. There are two main branches. In the open Catalan, Black takes on c4 and tries to hold the extra pawn, while White regains it with Qc2 or Qa4 and enjoys a lead in activity. In the closed Catalan, Black keeps ...d5 and ...c6, and White probes slowly with Nbd2 and a later e4. Black's key defensive resources are ...Bb4+, ...c5 and a timely ...b5 to hold the pawn. If the pawn grab fails, retreat to a solid setup instead of clinging. Typical errors for White are sinking the queen on c2 without a plan, and for Black leaving the c8 bishop undeveloped so the queenside never untangles. Neither side should drift. Tip: when playing White, count the pieces on the long [diagonal](https://georgelichess.com/glossary/diagonal.md). If you can add a rook on c1 and a [knight](https://georgelichess.com/glossary/knight.md) on e5, the pressure grows without any [pawn break](https://georgelichess.com/glossary/pawn-break.md). ## Example position The open Catalan. The bishop on g2 stares down the long diagonal while the queen on c2 prepares to win back the pawn on c4. Position (FEN): `rnbq1rk1/ppp1bppp/4pn2/8/2pP4/5NP1/PPQ1PPBP/RNB2RK1 b - -` A neighboring idea is [Fianchetto setup](https://georgelichess.com/glossary/fianchetto-setup.md). A fianchetto setup is a whole formation built around a bishop on a long diagonal, typically pawn to g3, bishop to g2, knight to f3 and short castling, used by either color in many openings. Also worth reading is [Spanish setup](https://georgelichess.com/glossary/spanish-setup.md). The Spanish setup is the White formation from the Ruy Lopez, with the bishop on b5 or a4 pressuring the knight on c6, and later c3, d4 and h3 to build a strong center and keep tension on e5. Compare it with [Transposition](https://georgelichess.com/glossary/transposition.md). A transposition is a change of route, most often in the opening: the moves come in an unusual order, yet the board ends up in a position normally associated with another order or even another opening. Opening ideas such as "Catalan setup" are easier to keep when they are tested on your own games, which is what a [first lesson](https://georgelichess.com/book/first-lesson.md) with George Li begins with. ## Related terms - [Fianchetto setup](https://georgelichess.com/glossary/fianchetto-setup.md) - [Opening principles](https://georgelichess.com/glossary/opening-principles.md) - [Gambit](https://georgelichess.com/glossary/gambit.md) - [Transposition](https://georgelichess.com/glossary/transposition.md) - [Opening repertoire](https://georgelichess.com/glossary/opening-repertoire.md) ## Guides that go further - [Most popular chess openings and win rates](https://georgelichess.com/chess-opening-statistics.md): The most played openings, how often White wins, and how the numbers change with rating, computed from public games. - [How to choose a chess coach](https://georgelichess.com/how-to-choose-a-chess-coach.md): What to decide first, the questions to ask, what a first lesson should show and the red flags to avoid. - [The first lesson](https://georgelichess.com/book/first-lesson.md): A game review, a read on your level and a written study plan from George Li.
