The Closed Sicilian is a way of meeting the Sicilian Defense in which White avoids the early d4 break and instead develops with Nc3, g3, Bg2 and d3. The Closed Sicilian is a way of meeting the Sicilian Defense in which White avoids the early d4 break and instead develops with Nc3, g3, Bg2 and d3, aiming for a slower kingside plan. In the [Open Sicilian](https://georgelichess.com/glossary/open-sicilian.md) White opens the center at once with d4. In the Closed Sicilian White holds that break back. A typical set-up is 2.Nc3 followed by g3, Bg2, d3 and often a later f4, with the king's [knight](https://georgelichess.com/glossary/knight.md) and pawns used to build pressure on the kingside. The structure stays closed for longer. White keeps the d-pawn at home and does not trade it for Black's c-pawn, so there is less early [theory](https://georgelichess.com/glossary/opening-theory.md) and fewer forced lines. This makes it popular with players who want a playable position without learning large amounts of [opening](https://georgelichess.com/glossary/opening.md) theory. Black has normal Sicilian resources. A typical plan is to develop the pieces, put a [bishop](https://georgelichess.com/glossary/bishop.md) on g7 and use the c-file and queenside space. Black can also strike in the center with ...d5 at the right time, which can quickly change the character of the game. A common [mistake](https://georgelichess.com/glossary/mistake.md) for White is to play too slowly and let Black equalize easily in the center. Another is to attack on the kingside before the pieces are ready. A common mistake for Black is to ignore the kingside plan and let the pawn advance gather speed. The example shows the usual formation: White has played Nc3, g3, Bg2 and d3, and has not played d4. ## Example position After 1.e4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 d6 it is White's move. White has played Nc3, g3, Bg2 and d3 without playing d4, so White's bishop on g2 sits behind the g3 pawn and the center stays closed.

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. Compare it with [System opening](https://georgelichess.com/glossary/system-opening.md). A system opening is a fixed setup that a player uses against almost any reply, such as the London or the King's Indian Attack, trading theoretical depth for familiar plans and a repeatable structure.
