Sat at 2/2 DC at DTD last night. 8 handed everyone has decent stacks, I've got about £250 after just doubling up villain with a light (and dubious) call. He's now on about £600
Most pots have had multiple players no matter what the raise and there's been plenty of straddling.
I've had absolutely no cards in the last 4 hours so I've not played many hands and my image is supertight. Not that villain cares to be fair.
The hand in question. It gets straddled to £4 and everyone calls round to me.
I've got

so I pot it up to £20. I'm expecting at least 4 callers so should I be potting with this hand?
Villain is sat to my left and repots to £72 which was not what I expected. Everyone now folds round to me. I put villain squarely on aces. There is no way he does this with anything else as he is pretty fishy and likes to see a lot of flops. I know that if I hit there is no way he is laying down so I decide to flat. Was this ok?
Flop comes

(not sure of suits but definitely rainbow).
Knowing that he is definitely shoving a pot bet and definitely potting if I check what do I do?
