I am roughly 1400 USCF and when I play against 1. d4, I tend to avoid the theoretical stuff (Benoni, KID) and defenses such as the Nimzo and QID (mostly anything hypermodern). So I stick with the classical 1... d5 defenses mostly. But, as I am becoming a better chess player I am looking towards other openings; I have played the KID over some casual games and of all of the other d4 defenses, I play the KID intuitively pretty well.
However, what is making me reluctant of it is defending against the Four pawns attack, Saemisch, and Averbakh lines (or anything where white plays a early Bg5) are a bit annoying. But I enjoy playing against the classical lines.
What would be a good choice?
