Reti Opening


Why use 2. g3 at all after c5? I normally play the Nimzo-Larsen with 2. b3 regardless of Black's response to Nf3, especially in blitz and sometimes in rapid. 1. Nf3 is simply a transpositional tool used by white to retain flexibility for a move or two while seeing what sort of opening black will adopt.

I've been wondering about taking up Reti. I've been reading Logical chess: move by move and been playing mostly e4 d4 openings and trying to hammer in ''the classical thinking'' before going for modern stuff. Anything you suggest to read about reti? Anyone in particular? Does someone on chess.com write about it?

Because Nimzo Larsen is not Reti and the discussion is about Reti.
