I'm calling here. If he's not betting trip 2's then I can assume that he may have a very much weaker hand. Maybe a flopped two pair or set gone bad but I'm not folding in that spot. Also, given that you have two hearts, its very hard for me to believe that he also has two hearts in his hand. He may have rivered two pair and think his KQ is good here but I think this is almost an insta call.
