About the Double Fianchetto Attack

White fianchettoes both bishops and castles, so the pieces on b2 and g2 rake the long diagonals while the center stays fluid. Black answers with a King's Indian arrangement built on ...g6, ...Bg7, ...O-O and ...d6. The most common reply, 6...e5, claims the center and blunts the b2 bishop. 6...Nbd7 and 6...Nc6 are also frequent, and the engine rates ...c5 and ...c6 as alternatives. The position is roughly balanced, with White scoring slightly better online.
