Good question, this is the Yugoslav variation by the way.
I have read Bologan's Kings Indian book and it's an excellent source for understanding the the themes, plans, and ideas in every Kings Indian line from the black side. Lines are enterprising and explanation quite thorough (it's 448 pages long) I like most of his opening suggestions against the typical white systems.
For good measure, your diagram position is covered in Chapter 30, Yugoslav variation, page 345, line A, 9.b3

P.S. For me the book was so inspiring I was studying it once a week in a nice library. Especially if you bring a board, notebook, and sticky notes with you, this is great.
Often 9. Nd2 is played here instead.
I'm looking for strategic motif(s) for this variation for black, such as annotated games or videos demonstrating a plan for black. If somebody could direct me to something tangible it would be great!
