You should have plenty of better hands in your range on the river to make a call, so I wouldn;t feel awful folding here. I don't think many ppl will try to bluff you off a pair and gutter type hand here bvb, especially when you have a bunch of trips in your range still, so I'd learn towards folding

I think this is a very tough spot because when you call twice on this board you usually have very few Tx compared to a lot of weak onepair hands. QK is the best onepair hand you will ever have in this spot. Not to mention that u never have any kind of full because i think you will raise all twopairs on the flop on this board. So you are really capped. When the opponent is a good player he does know that and that he can represent a fuckn bunch of strong madehands and that u can close to never call 3 barrels when u take that line..... i dont know exactly if it is +ev to call but vs some very aggressiv opponents which think the way described before and turn every fdraw AJ KJ J9 and so on into a bluff on the river i do make this call sometimes. But i need reads for it. Also i dont know if this is +ev at all in the longrun because it depends on so much things.....

I think BvB this should be a value 3bet.  As played your hand is basically a bluffcatcher on the river as he's unlikely to valuebet worse.  He can have a very wide value range which contains almost every combo that beats you, which (rough guess) is probably about 70 combos.  To make a call +ev nearly 30% of his range should be bluffs, so like 30 combos.  

I'm leaning towards a fold because I doubt he's bluffing as often as that here.
