I'm assuming you're trying to decide between something like raising and calling on the river, hopefully not folding/calling.

I'm not sure what you're asking here. A Tag is unlikely to call with a stupid ace. In your case, 100% call the river (obviously). I'm not sure about your river play to start with. Was the check to induce a bluff? Else I'd probably bet and hope he calls me with a lower PP the majority of the time, and i might just fold to a raise (even though I'm a river calling station)
