About the King's Indian Attack
White sets up Nf3, g3, Bg2, O-O, d3 and later e4: a King's Indian with colours reversed. It is an easy system against almost anything.
White plays Nbd2, e4 and often e5 to gain kingside space.
With a pawn on e5, White attacks with Nf1, h4 and Ng5 or Nh2-g4.
Black usually expands on the queenside with ...c5, ...b5 and ...b4.
