For chess improvement above and beyond tactical skill, this is probably the best book out there. Beyond providing the plans associated with different pawn structures, it covers general positional strategy within the context of common openings. Indeed, pairing the relevant chapters in this book (e.g., those on the KID) with a corresponding opening book (e.g., Victor Bologan's on the KID) is especially helpful for learning openings, as doing so adds understanding to move memorization.
"A general piece of advice for King's Indian players is to decide beforehand whether an opposite-flanks race is likely to work on or not. If Black is likely to lose the race, then he should not start it at all, and instead should attempt to find counter-chances by keeping the central tension." (p. 316)
On top of it all, the annotated games in this book (e.g., by Magnus Carlsen, Ding Liren) are fun to play through. So, even if considered merely as a collection of games, this book succeeds.
