AA against fish, bluff catcher?

1st hand, raise flop.. as played,river is disaster and should be a fold when he PSB..
2nd hand, your sizing is bad..

i saw sometimes he was bluff and so he did not seems tag.

TAG means tight aggressive. If a player never bluffs, he is a weak passive nit fish. When we look at his stats and your description, he indeed looks fishy.

First hand:
I don't usually respect those donks much but when it comes from a villain who looks more passive, I would respect them more. Still very often donks are some draws or weak pairs. I would call OTF and OTT. You have a nut flush draw to go with your overpair so I think those are standard calls. OTR villain increases his sizing and a donk 3 barrel line from a passive villain looks quite strong. I would definitely consider folding this hand OTR.

Second hand, I would just continue betting. Against this guy probably 3 barrel. Turn completed some draws but it also opened some new ones. You saw this guy call an all-in shove with a super weak hand so he probably is a calling station. Why slow down?
As played when he starts betting I would be a little bit concerned. What I would do depends a bit on his postflop tendencies but his preflop 45/14 don't suggest that he would pull a 2 barrel bluff against your missed cbet.

Hand 1 is ok imo. Board is 44 99 J and you have AA. He can have a J since he's is a donk.
Hand 2 when you start check-calling against this donks OOP and they bet strong...
Any 4 has a straight. I understand it's tempting to call after what you saw of him, but I think this hand is a fold OTR.

Densyosh and lai55, raise i think little bit overplay and i scary the weakest hand and every flush draws. I am not sure if i raise he going come on the turn just flush draw and middle or any bottom pair or gutshot, straight draw. Maybe river i had to fold, but he do this QQ, KK, or AJ maybe KJ. First hand is close but i thinked call is fine. Second hand, both you right, but when lost against him 84s, this board is very scary for me, and he try bluff i just let him but if not, always better for me. Turn i pickud up flush draw, maybe enough, maybe not, only J, but i this turn i do not know if i cbet he call worst hand. But i agree second hand i did not play the best.

@Todd : 1st hand, this is a donk bet, even with a bad sizing still betting OOP vs initial raiser.. Even if he folds you have max EV here, so if you size right he should call draws.. when you have best redraw this is time to get money.. maybe he would x/f turn so call flop doesn't change anything, but if you raise he might not fold and pot will be bigger..
