Villain's range looks something like this on river I think

I have given villain half of KJ hands because I don't know whether he raises them here or not. They could be in his range I guess, although if he has KJ some of the time I guess he can have QJ some of the time as well. I don't expect villain to have any flushes here, except KQcc. So question is, if we think villain overvalues his Jx hands, we have to call, if not, we have to fold.

I should also add I have purposely left out JT because I just don't think he raises w/ near enough the nuts here all that often.
