bet flop bigger because you can get value from 2 pair, lower sets, draws.
pot the turn because this is your money card and he's probably not folding anything he called flop with.
As played, I think this river is a fold. He can shove As and 9s, and I don't really see what he's shoving besides those hands. I doubt he's ever shoving with a bare ace. I doubt he's shoving with 8s or lower. He might shove a worse FH than yours, but don't you think that hand would have raised at some point before the river? I would probably b/f river ~0.25
