Can I get value here $10/20 NL..

[DanielDayLewis]

Villain is Lazy Mark on Party. He is like 40/5 but doesn't play TERRIBLE post flop but plays real passive. How much do you bet to here if you do bet? I'm really trying to value bet more often. The problem is he could have a lot of stuff here. Anyone just pot it? Anyone bet turn?
