Weird hand tonight (Wynn 10/25)

[Larry David]

Villain is new to the table. Looks like he may be a semi-fish, but not like a fish in the Bellagio 10/20.

Game is currently 7 handed:

Villain (~$3000) opens for $75 UTG-2
Hero (~$9000) raises to $250 UTG-1 w/ AK

Folded around to Villain

Villain re-raises $200 more to $450.
I think for a little and decided I would take a flop with position VS him.

Flop ($935) AKQ - rainbow

Villain leads out for $400

He never really hesitated throughout this hand, but at the same time, he didn't look like money was an issue for him (Rich doctor from LA). BTW, he bought in for $5000

Hero?
