BB check, Hero bet $14, BB call

Turn 8s ($54)

BB check, Hero check

River Jc ($54)

BB bet $30, Hero raise to $100

So yep, I know I am at the button of my range and it would seem like an std fold (maybe it is ) but what Im worrying it is if raising could have ev>0 (raising>folding) so:

Do you guys think it's worth to exploit villain ranges while we are having a range advantage? Or do you think we should recopilate some info about the player before making such moves?

Im raising river here because Im having a very clearly range advantage and have a nice hand to do it with, while he may have AJ,A8,JT,KQ which is the top of his range for betting the river (I think he'll be betting some of his Ax for value too good % of the time), but there are more straights in hero's range (79,Q9) and also JJ. Having Qd blocker reduces his straight combos, so what do you guys think about raising river?

I guess the main point is the difference between the combos he bet/call and bet/fold with, which I still have to check but obv we know that if there is a good margin then putting the 2nd bet on the river is the way to go.

But again, if we don't know the guy's calling range, maybe if he is bet calling all of his 2pr combos that makes my 2nd bet ev- ? What should his minimum defense frequency be here?

I may be wrong in many things but that's why I posted it to see different approaches, thank you guys!
