you played this so weird. Why did you 3bet pre instead of just calling? if you were trying to squeeze it needs to be much bigger ~60c

Once you 3bet pre you must lead out on this flop, why wouldnt you?

:/ hand

As played you have to call for three streets I think, I'm not sure though, it really depends on opponent. If he's been pretty aggro its easily a call for three streets...all in all though you really need to be barreling this flop against most opponents.

Why did you 3b then check the flop?
Flop is a must bet.

Why did you 3-bet? What are your reads on villains? Your 3bet is too small.

Checking flop is awful, why are you 3-betting and then going passive when you have an overpair? Are you waiting for sets before betting? Because if so, just call with JJ.

Super basic approach for nanostakes: when you have TPTK or overpair, c-bet flop 100% of the time. You almost certainly have the best hand but it's not such a monster that you can afford to hand out free cards.
