The whole idea of reti is based on hypermodern theories ie let black build a centre and then strike out.
One can also build your defenses 1st - g3, Bg2 and then 0-0 before focusing on the center.
There are 3 good books. The first 2 are reti. The 1st are quite interesting-it contains the entire white repertoire. The 2nd book is subtle and positional but it doesn't cover many lines. The 3rd -> what can you say its Kramnik also positional.
1) Dynamic Reti by Nigel Davis
2) Easy guide to reti Angus Dunniston
3) Openings for white according to Kramnik
As for KIA it is based on king indian defences but with white to move. However, that extra tempo does not convey any advantages. Middlegames are quite complex....and white can strike out in the kingside and sometimes the center.
even thought it is my favorite move... i don't know how to capitolize on the advantages (or shore up the disadvantages) using any manner of 1.Nf3 openings... I've heard of the reti, and the kings indian attack,,, but can't find any useful information on them... i got a book that is way to complicated and involved in variations and master games... but im no master and my games rarely follow anything like the books... any reccomendations on information that would actualy be helpfull.. like something that gives reasons why certain moves are good beyond other moves losing to perfect tactical play, the motives of playing certain variations... what the opponent should be trying to prevent me from doing and how to capitolize on my goals when he fails to do so... things like that
