King's Indian Defense, Fianchetto Variation

In the Fianchetto Variation against the King's Indian Defense, White plays g3 and Bg2. A fianchetto means advancing the g-pawn and placing the bishop behind it on g2, where it controls a long diagonal and helps protect the king after castling.

Compared with lines where White immediately builds a large center with e4 and f4, this variation usually emphasizes development, square control, and lasting pressure. The g2-bishop can influence the center and queenside for many moves, but its strength depends on keeping its diagonal from being permanently blocked by pawns.

Black still seeks pawn breaks, pawn moves such as ...e5 or ...c5 intended to challenge the center. White aims to keep a healthy structure and choose the right moment for e4, d5, or central exchanges. The battle is often less direct than in the Sämisch, but it can become tactical once the long diagonals open.
