Value bet my luckbox

[Silly String]

Villain was 19/6. I wanted to control pot on flop with strong chance he is carrying a better Ace.
How did I play turn & river? Is river bet too strong? I like to put people in a position to make those heroic calls. Should I have bet less, since he probably isn't on an Ace?

I think you played it ok, but here's my thoughts...he checked the flop, which probably means he is scared of the ace too or hit a set and wants to slow play, or maybe he's pot controlling an ace.

overall (trying not to be result-oriented, but it helps to leave out if he folds or not), I think this is a good spot to lead timidly on the river, like 1/4 or 1/3 pot.
if he was slow playing, and maybe with a good ace, he'll raise and you can push. he also might raise as a bluff. if he has a pair, he might think you have a worse one.
still I can't see this way being hugely different then just potting the river though.
