i think you should thank jesus that BB isn't in the hand. i 4bet 5.93 here and expect SB to fold just about always (even fish don't generally flat in a 3-way pot like this with AA or KK unless he's smart/psychic enough to know that UTG is gonna push). we're well ahead of BU's range and i'd need numbers here to know how we stand against his calling all in range. but even as it stands ANYTHING beats throwing your hands at the mercy of the flop and calling here and playing 3-way, OOP, without the initiative ('cause UTG stole it from you)...not to mention giving BU and SB a chance to push
