NL10: AQ hits TPTK, but OOP

[wattascoop]

Villain is 38/0/7 after 30 hands. It's been tough to get a read on him -- he'll play both made hands and second pair strongly, so I'm having a difficult time putting him on hands. I think the preflop raise and flop bets are standard, but should I bet more on the turn to discourage draws? On the river, do I check and re-evaluate?
