Looks completely standard.

fine

looks fine.

Seems like a nicely disguised 2-pair to me - well done for increasing the bet size on the turn. Surely a lot of the time people are calling these bets with AK or AQ.

So, what's the punchline? Set, or backdoor flush? Very hard to defend against either.
