King's Indian structure
The King's Indian structure arises when White's pawns on c4, d4 and e4 meet Black's pawns on d6 and e5; once White pushes d5 the center locks, and play splits into a White queenside attack and a Black kingside attack.
Black allows White a large center and builds a flexible position with ...g6, ...Bg7 and ...d6. The key moment is ...e5, and when White answers d5 the center closes and the two sides head in opposite directions.
White attacks on the queenside with c5, usually prepared by b4 and a knight heading for c4 or d3. Black attacks on the kingside with ...f5, ...f4 and ...g5-g4, first moving the f6 knight to d7 or e8 so the f-pawn can advance, with the bishop on g7 supporting from behind. Each side tries to be faster than the other.
When the center is closed, the plan matters more than the tactics. If Black's break ...f5 comes at the right time, White's king gets uncomfortable. If White's c5 comes first, Black's d6 pawn and the c7 square become targets.
Common errors are delaying the pawn storm, trading pieces that defend the king (for Black) or the pieces that support the queenside break (for White), and opening the center without preparation. Practical tip: whichever side is slower must find a defensive resource or break the center before the opponent arrives.
Compare it with Benoni structure. An asymmetrical structure where White has a pawn on d5 and Black has pawns on c5 and d6, giving White a space edge and Black a queenside pawn majority and active piece play.
Compare it with Kingside pawn storm structure. A kingside pawn storm structure arises when the center is locked, so one side can march its kingside pawns toward the enemy king while the opponent counterattacks on the other wing, as in the classical King's Indian Defense.
It sits close to System opening. A system opening is a fixed setup that a player uses against almost any reply, such as the London or the King's Indian Attack, trading theoretical depth for familiar plans and a repeatable structure.
Opening ideas such as "King's Indian structure" are easier to keep when they are tested on your own games, which is what a first lesson with George Li begins with.

In a closed game, locked pawn chains and blocked central files restrict the pieces, so maneuvering and pawn breaks matter more than quick tactics and direct attacks.
A space advantage means controlling more squares, usually through advanced pawns, so that your pieces have room to maneuver while the opponent has little room and finds it hard to exchange or regroup.
A pawn break is a pawn move that makes contact with an enemy pawn or chain, forcing an exchange that changes the structure and gives your pieces new files or diagonals to use.
An asymmetrical structure where White has a pawn on d5 and Black has pawns on c5 and d6, giving White a space edge and Black a queenside pawn majority and active piece play.
