It's a difficult one. Even though UTG+1 is a calling station you would have thought that the fact that he called your huge pre-flop raise means that he has at least something half decent, but the range of hands for a player like this is pretty broad - could be a pocket pair lower than TT but not 99/44, A-x, KQ, QJ, KJ...I would have thought that AA, KK and QQ would be an instacall/reraise to your big raise.
I think I would have pushed the flop with this as you're better off taking the pot now rather than risk him hitting a straight draw or pairing an A, K or Q. If you don't think he has AA, KK or QQ I think there's no reason for you to believe that you don't have the best hand with the flop all undercards.
As played, at this point you're pretty much pot committed, so although I think there's some chance that you're beaten, I would push the turn. You never know, the A could be as much a scare card for him as it is for you.
Am I missing the boat here?
