Hi guys!

I was wondering if there's a preflop spot (or several spots) in NLHE 6max 100bb game where we should call our entire continuing range vs 4bet? What about deeper stacks? Or should we always mix calls and 5bets? I was thinking this might be the right play when ranges are extremely narrow & facing a value-heavy range when OOP (e.g. BBvsUTG) / facing bluffheavy range when IP (e.g. BTNvsCO)? What do you think?
