I would DEF not fold. Very likely shove. You're utg, so the only hand that beats us is KQ and given the suits out there, KhQh is even blocked, so he would have to be calling an offsuit KQ.

He can have AK given you're utg, and he can certainly have QQ, and slowplayed 66 and even the one combo of 77.

I'd ship. No way is he folding Q's full, and likely not 6's full. Esp since he thinks you could be getting tilted/fed up.
