Black's queen bishop is also fianchettoed, but the knight pawn has moved forward two squares, making this a "long" fianchetto. The b-pawn also controls the c4-square, which is often advantageous. If White plays the King's Indian Attack 1.Nf3 2.g3, Black may play a long queen's fianchetto to oppose White's bishop and make it more difficult for White to play a c4 . A long fianchetto on the kingside is more rarely played, because it weakens the pawn shield in front of the castled position and controls a less important square. Nevertheless, Grob's Attack 1.g4 and the Borg Defence ("Grob" backwards) 1.e4 g5 are sometimes played by players such as IM Michael Basman.
