I like the flop raise, you could win it right there, and you do have outs.
Since he's unkown, I really want to show this down early on to get a read. So I chk behind the turn and call a river bet UI.
You have some showdown value.
A pair or stronger will never fold to that turn bet.
A check on the turn by you might induce a bluff on the river by busted draws and weaker Ax hands.
