Hero bets ???

I'm a little bit unsure if I should bet the river again. After the flop and turncall I have no idea what he can have. On the flop, he can't possibly have a drawing hand and then with the Ace on the turn I think he will raise me if he hits it.
So, on the river, do you see any worse hand which would call a bet? And if I check the river, to which amount would you call a bet?

Not gonna be betting, not likely that you get called by anything you beat with river bet.
I check and either call or fold depending on reads (which there are none!!).

If this guy is real passive and puts $5 on river then I fold, on the other hand, against someone more aggro check calling their river bet comes off better since your inducing more bluffs.
