A fianchetto is a development scheme where a player advances the g- or b-pawn one square and places a bishop on the long diagonal (g2/b2 for White, g7/b7 for Black). It is central to openings like the King's Indian Defense, Dragon Sicilian, English Opening, and Catalan. The fianchettoed bishop exerts long-range pressure but can leave weak dark or light squares if traded.

Frequently Asked Questions
No. Queenside fianchetto (b2/b7) is common in the English, Queen's Indian, and some Sicilian lines.
Usually avoid trading it lightly — the surrounding pawn structure creates holes (especially f3/h3 or f6/h6) that become weak without the bishop.
