I think this pattern/combination of book types can be used to seriously learn just about any sound opening that comes to mind. I've already done it with the King's Indian!  Here it is - you need the following:

1) a generally good book that really insists on teaching you the main ideas of the opening first and foremost: Robert Bellin & Pietro Ponzetto's "Mastering the King's Indian Defense"; works miracles together with "Mastering the Modern Benoni and the Benko Gambit" by the same authors;

2) a book on the opening given from a perspective of a strong player who is its prominent exponent, or even a specialist, with original analysis of all the main and side nuances: Victor Bologan's "King's Indian: A Complete Black Repertoire"; includes directing play towards the Modern Benoni and even the Volga/Benko Gambit in some lines(!);

3) a book with classical examples of the opening play and principles dating back to its very roots, possibly written by a classical exponent of the opening as well: David Bronstein & Ken Neat's "Bronstein on the King's Indian"; 

4) a tactics book exclusive to the opening: Gennady Nesis' "Tactics in the King's Indian" is the only one I know about in this case, but there can be found many interesting scripts and articles for this purpose;

5) a study of the reversed version of the opening, if applicable; in this case, there are some nice books to choose from, like John Emms' "Starting Out: King's Indian Attack", Angus Dunnington's "The Ultimate King's Indian Attack", and John Hall & Jan R. Cartier's "Modern King's Indian Attack: A Complete System For White"; if you know about any other good book on the KIA, please let me know!

Of course, anything and everything you can later add on top of this would be just great! So, what do you think? If you like the idea, I'd like you to help me build such repertoires for other openings! You name them, I'm curious if we think likewise about their possible natures in relation to their studying methods! 

P.S. This topic was originally posted in the Chess Openings section, but it would be more appropriate here, right?

As for other books that can help you with the KID (and KIA in a way), there are such as Joe Gallagher's "Starting Out: the King's Indian" and "Play the King's Indian" (the latter of which is exclusively about the opening from Black's point of view), then at least two books written by Raymond Keene & co., as well as John Nunn & Graham Burgess' "The New Classical King's Indian", but, as I had indirectly suggested, they might be too theory-oriented for beginners, even the "Starting Out" (at least in my opinion, it's still less understandable than my suggested program in the first post, but see for yourselves), so I'd study those only after I read what Bellin/Ponzetto, Bologan, Bronstein/Neat and Nesis had to say on the matter of the topic.

I read Play the King's Indian by Joe Gallagher and absolutely loved it.

that said, the King's Indian is not an opening for beginners because it is not easy to play.

I would recommend switching to something else unless you have serious time to study master games.

Thanks for the concern, but I didn't really start to study the suggested program yet. I'm going to find time for that eventually, but for now I just wanted to see if the repertoire seems as good to you all as it does to me. So, have you looked at other aforementioned books?

I know the last comment was made like 2 years ago, but what do you think is the best king's indian book for a 1600-1700 player who has just played the king's indian for a few months?

Belin and Ponzetto's book will give you everything you need except for 'up to date' theory.
