Villain 31/25/6.0 over 52 hands. No real stats or reads about 3bet pots, ATS 57.

I wasn't sure I wanted to stack of on the flop, so I thought I'll take the pot control line IP.
Questions basically are, do you like checking behind flop or do you like betting? What's the plan for a raise?
Also, is river a standard call?
