I dont have many hands with villain as I dont play holdem much. He is 25/23/4 hadn't seen him do anything dumb. I was playing 21/18.
I do 3 bet this hand often, but not a lot vs ep raises, so I realize I could have done that if I chose to.

What kind of range can I give him here for calling the check raise?

AA, KK, KJs, KQ? AK, JJ, 33, QT? and maybe any random xxd he decided to raise in ep.

Hero???

or maybe the check raise is where I messed up.. I'm thinking leading this would be better.

c/c flop is also an option. If Villain has no hand he will mostly give up on the turn and you can bet the river even unimproved...

yes c/c is an option too.. basically I could have done anything on that flop and nothing is really wrong.. it's just when the turn comes which spot puts you in a better position to win the pot/get his stack if you hit.
