1/2 JJ in pos 3bet pot vs reg

[bspahn]

never played with him before, stats were 20/17/2.2 with 3bet 9.3%

to a CO open obv his 3bet range is huge. I think I'm just getting into a variance war if I 4bet/get it in here pre, so I opt to call because I'm in pos.
Flop is perfect for him to cbet any 2 so I have to call. turn changes nothing. now, can someone pls give me the math here so I can get a better understanding of how often I should just get it in here? One issue too is I hadn't rebought yet and at this stage I was only $111 behind. So from what I know the math tells me I have to be ahead
~ 32.7% here. What's the range we're giving him here? 22/88/KK/AK/AA ?

I fold here, but I 4 bet this pre most of the time, 9.3 percent 3 bet is rather high and so many regs and reg wannabes spaz when they think they are getting replayed back at by the btn/co after 3 betting in the blinds. Just make it $55 pre and call a shove.

I dont hate flatting pre, as long as you make sure to be balanced here somehow. As played I like your line and fold turn, people dont bluff too many turns in 3bet pots oop.

[bspahn]

Yes in general against such a high 3bet % I will flat a ton of hands here such as 99-AA, AJs/AQ/AK etc (I might 4bet some AK)

I can call a cbet here with most of this range, and bet/bluff blank turns if he checks.

played fine and i fold the turn. 4bet/get it in has more merit obv as your stack gets shallower. i still like calling IP here with ~$170.
