tough river #1

Your 3bet is so small that villain could have so many suited connectors like 98s/76s/65s, he could also have 66 and turn all these hands into a bluff. Even though it's the top of your range, I would rather call with AhAx because I think villain is polarized so I'd rather block his value-range. Problem is AhAx is only 3 combos ♦ I guess I end up f*ck-calling in game, hoping to see some random spew/weak hand turned into a bluff. I'd be folding the 6 heart-less KK/AA combos + weaker hands and call/shove sets and flushes.

I would also call, as this is somewhat the top of your range, and if you fold this you get theoretically bluffed too much (?) (opinion from a PLO player haha).
But agree that you it sucks

Villan's line looks like he is a fish.
For that sizing it is easy call. He might has QJ, J8, 78 types of hands.
