I like your line although I think a bet to 30 on the river is better.

I think the only hands he calls or raises with here are slow played trips/boats and an AQ that figured he was ahead of your range on the flop. (If he doesn't 3bet often, AQ is probably in his range.) I think he'll have those weak pocket pairs a huge portion of the time, so betting again seems fine.

This is definitely a note-taking hand to find out how he plays.
