QQ and AKo step down to calls. Bloating a pot 500bb deep against an EP range is volunteering for the worst spot in poker.
The 3-bet range condenses toward hands that welcome a giant pot; almost everything else that plays well flats. Bloated pots with dominated hands are how 500bb stacks vanish.
The tightest confrontation at the table: an early open, and you right behind it with six players still to act.
Assumes a ~4bb open; 3-bet to ~3x the open in position, ~4x from the blinds — larger as stacks deepen.
