King's Indian Defense: Orthodox Variation
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2
In the Orthodox Variation against the King's Indian, White creates a three-pawn center and develops his kingside naturally. Generally after a later ...e5 White will create a pawn wedge with d4-d5, followed by queenside play. The opposing pawn chains create spheres of influence on opposite sides of the board.
Pros:
- Sound play
- Gives White a space advantage
- White can get a strong attack on the queenside
Cons:
- The white king can come under great attack
- Very theoretical
