Key King's Indian Gallagher diagrams
These python-chess checked diagrams use final-move arrows from each displayed sequence: 6...Nbd7, 8...exd4, 9...Re8, 10...a6, ...Nc5, ...Rb8 and ...c6 support.
Practical warning: the tempting line 10.h3 a6 11.Re1 Rb8 12.b3 b5 is avoided here because 13.Nc6 creates a tactical problem. The safer diagram keeps the b-pawn on b7 and uses ...c6 support first.
8...exd4 defining capture
This is the earliest central capture that defines the Gallagher structure.
