Overpair

I would rather squeeze 99 than play it OOP in MWP, but when you decides to call - for my it is overtight fold.
Villain might have c-bet hands like missed AK, AcKc, AcQc, AcJc, some suited one gappres. I think that you have one call there.

And another reason to call is - according to what you have said - that villain seems to be a fishy player (sizing of this squeeze is a decent proof).

I think I would like donking more than x/c. When we x/c - we let him see turn and he has lot of equity, which again he might bluff on next streets.

When we donk, he might fold some Ax. If we donk like pot, maybe even AK will fold and that would be good imo.

From the SB no calling but 3bet all premium hands. On the flop try to make it to showdown with a small pot. Overpair too strong to fold at the moment.

Preflop is fine. OTF I might lead because we are multiway but check calling wouldn't be bad either. Folding is way too tight here.

Preflop we can call.
Postflop fold is tight . Call once.

Squeeze it, especially when having a squeezer to the left.

Thanks, about that 3 betting pre-flop, I play to set mine, so making 3 bet wouldn´t be profitable, would it?

Not sure it is tight, I guess we deep, that is nl2 and opponent CB in MWP with pretty good sizing. What does he represent? I think it is premium hands. So, plan was to hit the set. Good fold.
