Say we don't under rep our hand pre with the flat and choose to reraise the opener
how would we then proceed once this guy puts in the 4bet?
I think we get stacked pretty much whatever here. The flatting helps me avoid it though if the sb 4 bets as he would withh KK and then UTG 5 bet jams. That was the only folding scenario.
Had i 3 bet i would have 5 bet jammed to the 4 bet anyway.
