25NL: 33, bet turn?

[foal]

I know no worse hand calls, so I figured checking and possibly inducing a bluff would be the best way to go. I was pretty sure I had the best hand on the turn, but a river card could have easily changed that so maybe I should have protected my hand? Then again I don't really like the thought of getting aggressive with 33 OOP. Luckily the river was not very scary.
