Above is the setup I normally play as black. Nf6, e6 and Bb4, then fianchetto on the queenside. Later on after I castle I will play c5 or d5 to challenge the center. If white challenges the bishop on b4, I usually trade it for the knight.
I don't have a lot of opening theory memorized but the above setup tends to work OK against a bunch of variations by white.
Great thing to start studying the KID.
While studying it for approximately four hours per day, it's assured you will have a slight grip on it after a couple of years or so.
