Fianchetto

Fianchettoing (fianchetto; ital. fianchetto - short for fianco - flank) is a flanking development of the chess bishop in the opening.

The idea behind fianchetting is to establish figure control over central squares or figure pressure on the opponent's pawn center. History

At the end of the XIX century fianchetto was introduced into tournament practice by Howard Staunton and Louis Paulsen, and already in the XX century fianchetto is used universally. A similar scheme of development is used in many openings, such as the Royal Gambit, Defence of St George, the Old Indian Defence, the New Indian Defence, the Catalan Opening and others.

Exchange fiancheted bishop can lead to the formation of weak fields around the knight's pawn
