I think I call a lot of pocket pairs, and hands like AQs+ in the BB vs that min 3b. It's basically like we are calling a min open if we were in another position since it is only 240 to call..
I prefer to call with JJ here unless I have a little more info on the villain. I would 4b if we were a little more shallow, or if I had info that the villain loves to get it in with pocket pairs lower than JJ or just spazzes out a lot. I think when we are this deep with only 80 hands on a villain, we will be behind his 5bet range a lot.
I think if we call JJ here, we need to call with a lot of pocket pairs to balance out our range, even though it's not really balancing if we are just adding similar hands lol. I think our hand is rather transparent here when we overcall, but villains are typically always bad. They don't pay enough attention, and will just put you on AK lol.
I do like to c/r this flop because I am probably not getting another bet out of him if he has air. If we donk, we get 0 value from his air hands. I think it's better to check, allow him to bet, then raise because we get value out of a lot more hands. If he continues with us, he will have overpairs, Jx, 66-TT. We can continue to fire at him on the following streets. Check/raising allows us to get value out of bluffs, and also if he has a hand, we will still get value out of it. It's obviously fine to get it in on the turn, he can easily have AJ, 33, 22, AK, KJ.. Although, he probably has AA since you posted this hand
