Black allows White to control the center with his pawn formation. After that Black attacks it with the pawn moves e5 or c5. The Kings Indian is suspected not to be quite correct, but analysis and practical play by strong grandmasters made it popular. There are various plans in this opening and the black bishop on g7, which exercises pressure on the long diagonal, plays a major part in those plans.
If you are a beginner this opening is too complex and too difficult to understand for you.
