I raise in MP with JJ to 60. Button Raises me to 180 and SB 4bets to 420. What do we do with JJ? Also what about QQ or 1010. With AK, AA, KK I think Jam is best.

I expect buttons range to be fairly tight and 4better in SB to be about 1010+, AQo+. Maybe AJs.

Can we ever flat here? Or is it decision between jamming (mainly for fold equity Vs AQ and potential AKo) or folding?

Assume 100bb deep
