Fianchetto

v. (in Chess) fianchetto a bishop

n. (in Chess) move of a bishop from its original position by moving forward 1or 2 pawns to allow movement along the bishop's diagonal

In chess the fianchetto (/ˌfiən'kɛto/ Italian "little flanking") is a pattern of development wherein a bishop is developed to the second rank of the adjacent knight file, the knight pawn having been moved one or two squares forward. The fianchetto is a staple of many "hypermodern" openings, whose philosophy is to delay direct occupation of the center with the plan of undermining and destroying the opponent's central outpost. It also regularly occurs in Indian defences, so-called since fianchettoing was the standard practice in chess as it was played in ancient India. The fianchetto is not usually considered appropriate in open games (1.e4 e5).
