Kinda gross. I tend to think you won't see many hands like AQ going for the x/c x/r line on this type of board so it'll be hard for villain to have a lot of bluffs. I'd probably fold though it really sucks if villain is just bad and overplaying something like JT.

Given that it's NL2 good ol' fashioned Baluga Theorem still applies vs. most players and unless you have a solid piece of info suggesting that going broke might be optimal I'd play the hand the same way.

I'd play it the same way against an unknown. On a rainbow flop villains aren't always going to raise sets,plus at 2NL it's believable he can have a decent number of two pair combos. It's sick to recomend folding when I see quite a few micro villains with a pair plus draw raising incorrectly in single raised pots. But here once you bet twice I doubt he expects you to fold an overpair.

This is a very unfortunate spot. One of the problems here is that is is not beyond the realms of possibility that villain is overplaying JT, or even hands like AJ where he decided to float the flop. We are of course going to be beat here a decent chunk of the time but given the price we are getting I would probably click call but I'm for sure not happy about it and I wouldn't argue against the fold at all.

I like your fold here. I just fell when people are cold calling 3 bets, they are doing this most of the time with pocket pairs. It's a really hard spot at 2 NL when everybody seems fishy and you can easy find a hand to put him on that you beat.

Folding here makes you be disciplined. And you need it in poker.
