I'd like to know what (if any) read you have on UTG as well. This might (big emphasis there) be one of those rare occasions where I'd think about check/raising the river with nada, but I'd really need to know that not only is Button capable of folding an ace there, but also that UTG is capable of folding...whatever he's got. Based on your limited read on Button I seriously doubt that he could beat ace kicker here, although it's relative likely he could tie it.

That's as played; I'd typically check/call the turn (depending on action), which pretty much kills any believablity that a river check/raise would have. I don't mind firing the second barrel tho, as your opponents are going to be peeling this flop with all sorts of things they wouldn't call a turn bet with.

Bonus: check/fold > check/raise > bet/fold > check/call > bet/call. Obviously depending on opponents (HU vs Button that's the order I'd go with).
