Bad play or Cooler?

I would fold pre vs the 3bet and even more so given it's a 10bb 3bet slightly bigger than standard sizings but vs 9x id be folding pre as well.On the turn i think you can fold as well your calling 4th pair it seems a little optimistic to me.And on the river id probably just call the 50bb river 3bet it's a really nutted line by villain.What worse hand takes this river line ? and if villain has worse value hands to 3bet the river with do you think they can call a shove ?.Hands like AK AA aren't taking this line and even 2 pair are just calling your river raise.Villain needs to be able to overplay 2 pair here K7 K5 type hands to make shoving profitable imo so id just call the river 3bet and i wouldn't be to thrilled about it either.

PF is a fold, don't see a good reason to call this raise.

To estimate whether to call a 3Bet with a pocket pair, there used to be a "Call 20" rule.
If the amount of the call required times 20 is less than the effective stack, then go ahead and call.

This assumes that you will get his entire stack if you hit your set.
This doesn't always so you need to be even more careful.

In this case the effective stack is 127 BB, you need 7BB to call.
7 x 20 = 140, so this is a clear fold.

The reason for the rule is the idea that most of the time you'll miss your set, and you'll make it back when you hit and stack your opponent.
