Hello everyone . I am playing chess seriously for a year and throughout that year I changed my openings several times . First I played catalan then English then Reti. I had books for catalan and English but none for Reti. I want a book for Reti which can teach me ideas for delayed c4 Reti, kings Indian attack . I generally play Nf3 Nf6 g3 g6 Bg2 Bg7 O-O O-O c4 . Please recommend me a book it can be two books teaching different things like first one Reti and second one KIA
