Standard 4Bet fold?

Villain is really aggressive so far. That makes it tough to fold JJ on a 5bet shove. Against a random villain I would fold for sure.

Do you have a 3bet stat on villain ? i think vs someone with a very aggressive table image 40/30 albeit only 53 hands. We should probably make the decision to stack off preflop.Had it been the CO that 4bet i think yes we can make the 4bet fold with them being 22/9 over 145 hands.

Although 53 hands is not a big enough sample size to be discussing 3Bet tendencies, I'm not likely to give him much credit.
I would 4Bet larger though, since it is 3-way at this point.

I would hope I could find a fold here, because at best you're flipping vs AQ+ and losing to QQ+
Once villain is known better, this might be a call -- but only if we can see him do this with TT and lower pockets

alternatively you could look at your own cold 4 range and calculate, how much of it you need do defend not to give autoprofit.

against the other two villains it would be an easy / happy fold.
Against this one you are triggered to call. Rationale (because probably best case scenario we are flipping) says to fold it, because either we win his bluffs or barely flip it.
The low variance root says again : fold and move on.
