-Haven't played that many hands with this villain, but he is running at 50/30 and from what I've seen is a call centre, pretty passive

Hand 1:
-I figured I was way ahead of his range, and that I couldn't just flat call to set hunt so I raised him hard
-he has been raising light and calling all re-raises
-what to do on this flop? only half-pot bet left. Committed at this point?
