33 Is it possible to ifind a fold here?

You played it well and just got unlucky losing to a bigger set. However, I would have check/folded on the flop.

Actually you should be folding it preflop. This is a terrible reverse-implied odds hand when out of position.
OTF its closer, but I agree folding isnt bad at all.
The turn 3bet is a little optimistic. You should be more careful when you are this deep, so calling his raise might be better.

To answer your question - the way you played it there is no way you can fold for 80 cents

I think pre flop call is ok to set mine. Flop would be x/f. We don't have to protect our hand so much so calling villains raise OTT would be good. As played you can't fold. You just got unlucky here.

i think becouse you taked this line you played fine..

vs a tight opener we can call preflop. vs a wide opener we can bluff 3 bet preflop.
we cannot fold postflop.

At nl2 every pocket pair is profitable to play due to huge implied odds. About that spot of yours, nothing to write really, you didn't have to donk since the board is relatively dry, x/r will do.

The flop is a check-fold, but that is not what the OP's big question is.

Namely, "Is it possible to find a fold here?" refers to losing a 162.5 bb stack with a full house. The answer is a big NO. Not 162 bb deep with a full house and with that betting pattern. Not ever.

I also couldn't find a fold postflop. Pre-flop remains in dispute.

I think you played the hand just fine, you got very unlucky with the set over set, pre flop call was fine as well.

He is in the small blind and is facing (probably) a pretty wide CO 4-handed range. How on world are you expencting to make money with 22-66 out of position? If you somehow manage to put his stack in the middle when you flop a set, like 30% or more of the time you would be "coolered", you will have a really tough time value betting it OOP, and the other 7/8 times that you do not flop a set you would set money on fire.

Sure, if its multiway or there is a big fish in the hand, you can set mine, but is it the case?

I think you played the hand just fine, but you got very unlucky.

Does Hero have to call preflop?
The stacks are deep enough for setmining.

Does H have to donk the flop?
Hero didn't hit his set. He has bottom pair. Villain is an unknown.
Does H bet for value? Not with a bottom pair.
Does H has to bet for protection? H could have easely have the worst hand already.
Does H bet as a semi-bluff? H has not enough outs for the implied odds.
Does H bet as a bluff? H is playing against an unknown.
So Hero does not have to bet on the flop.

If Hero doesn't bet the flop, how should he act on a bet from Villain on the flop?
Villain is an unknown. Hero didn't hit his set. Hero has bottom pair. IMO hero has to fold.

To play low pockets our plan is to catch a set and get stacks in asap right? When we are deep sets goes down in equity especially low sets. Being deep we would like to play possible nut made hands which cant be drawn out. Sets can be easily drawn out as you will not stack on flop or even turn and facing aggression with set you just make your life hard. Dont you like easy life? Fold pre.
