- Bishop

- Opening
Developing a bishop to b2, g2, b7, or g7 so it controls a long diagonal from behind a knight pawn.
Where the term comes from
Italian for 'little flank', from fianco meaning side. The development scheme was viewed with suspicion for centuries as too slow, then rehabilitated by the hypermodern school of the 1920s — Réti and Nimzowitsch argued you could control the centre from a distance rather than occupying it.

How do you get better at using a fianchetto?
A fianchetto bishop is powerful only if its diagonal matters. Watch for blocked central pawns that make it passive.
