A fianchetto is the setup where a bishop sits on b2, g2, b7 or g7 behind a pawn that has moved one square, so that it eyes the long diagonal from a distance. A fianchetto is the setup where a bishop sits on b2, g2, b7 or g7 behind a pawn that has moved one square, so that it eyes the long diagonal from a distance. The name comes from an Italian word meaning little flank, and the picture is of a [bishop](https://georgelichess.com/glossary/bishop.md) tucked behind a knight-file pawn instead of standing in front of its pawns. After g3 and Bg2 (or ...g6 and ...Bg7) the bishop looks along the board's longest [diagonal](https://georgelichess.com/glossary/diagonal.md) from far away, pressing on the center and the opposite corner while few enemy pieces can challenge it. The bishop also becomes part of the king's cover. Beside a castled king it guards the [squares](https://georgelichess.com/glossary/square.md) around it, and the pawn in front of it stays on its own file. In exchange, f3 and h3 (or f6 and h6) lose their pawn guard, so trading off the fianchettoed bishop can leave real holes on those squares. Fianchettos suit setups in which you let the opponent build a center and then attack it, as in the King's Indian, the Catalan and the English. They work only while the diagonal stays open. A pawn on e4 or d5 can shut it, and then the bishop is mostly a defender. A [knight](https://georgelichess.com/glossary/knight.md) on f3 also blocks the bishop on g2 until it moves. A practical rule: before choosing the setup, name the [pawn break](https://georgelichess.com/glossary/pawn-break.md) that will free the bishop, and keep the bishop unless you get something concrete in return. ## Example position Both sides have fianchettoed on the kingside: White's bishop on g2 stands behind the pawn on g3, Black's bishop on g7 behind the pawn on g6. Each long diagonal is open up to the first pawn in the way, which is c6 for White's bishop and d4 for Black's. Position (FEN): `r1bq1rk1/pp1nnpbp/2ppp1p1/8/2PP4/2N1P1P1/PP2NPBP/R1BQ1RK1 w - - 0 1` Also worth reading 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. Compare it with [Hypermodern opening](https://georgelichess.com/glossary/hypermodern-opening.md). A hypermodern opening is a bet that a pawn center can be undermined: the player develops pieces to the flanks, often with fianchettoed bishops, allows the opponent's pawns into the middle, and hits them later with pawn breaks. Compare it with [Pawn shield](https://georgelichess.com/glossary/pawn-shield.md). A pawn shield is the group of pawns standing directly in front of a castled king, typically on the f, g and h files or the a, b and c files, that blocks enemy lines and covers the squares ahead of the king.
