set vs river overbet again and again...

Raise OTF. If not OTF, then raise at least OTT.

Pretty much only AA beats you.

It is possible that villain overvalues his TPTK and plays like this. He maybe could also 3bet pre with 22 or 44. He can have A2 or A4.

I just wouldn't put villain on only 3 combos and fold. You need to win about 42% to make the call profitable. If there are only 3 realistic combos that beat you, villain doesn't have to play many AK,22,44,A4,A2 hands like this to make this situation very profitable for you.

I quite like the flop call but on the turn it's time to raise.
As played you just can't fold. Can't even tank. You might have a mental problem with playing deep indeed. Maybe it's also why you didn't raise before ?

Folded that one, 5 minutes after i was on tilt for folding. And this happened. Call of frustration.

3bet a bit bigger versus 3x OOP.
I'm not sure at all how I'd handle this spot, from flop to river I see several possibilities lol.
Anyway as played river it's close because you are basically calling to split.

if you plan to fold 66 in this spot just dont call preflop low pocket pairs. This is why you called the 3bet, isnt it ?

h1 is an "easy" call, h2 an "easy" fold (most likely a call in theory but i really don't believe they have a good enough bluff frequency).
the fact that you don't even raise at any point in h1 due to what can only be explained as fear of running into exactly AA shows that you shouldn't be playing deep, as it does happen that you will be making marginal (and not-so-marginal) decisions for large amounts of money and it will happen that you are wrong sometimes.

i was also a risk-averse huge nit at some point, i understand. i still don't play deep very often, even though i believe that i also have a good edge in the format (you should make a bunch of small but impactful adjustments)

OTF i would reraise for sure, would do it again OTT and would pay his all in otr.

Im sure villain has top pair
