Hero ???

I don't think he has a strong ace. Either he bluffs with a spade or has a middle pair. I think I'm ahead, but I'm not sure if I should exercise pot control to be able to call a river bet from them or should I value bet with a raise on the turn (if the latter - how would I respond to a shove with a spade or a brick on the river?).

What are your thoughts?
