Well I did muck it. Seemed nitty on the spot, but I also have to add that my own image was very nitty since it was only the second hand I was playing out of 26, so the more I think about it, the more I doubt he flats a UTG raise in UTG+1 with AQ. Also since I pot the flop OOP against two opps, he must know I have a decent hand. My best guess is TT,44.
