In chess openings, fianchettoing a bishop (developing it on g2 or b2 after playing g3 or b3) is characteristic of the Indian defenses, including King's Indian, Queen's Indian, Nimzo-Indian, and related systems. The term "Indian" is the common thread linking these hypermodern openings that emphasized flank development. The French, Sicilian, and Caro Kann defenses typically develop the bishop to more active squares along the central diagonals.
