The 4-bet range trims to premium; the call range holds everything that can flop a monster in position.
4-betting narrows to the very top; suited hands with nut potential call more. The question on every street becomes: which hands are happy getting 500bb in?
You opened the button wide; the small blind 3-bet, as they should. You hold position and the wider range — both matter.
Assumes a standard 3-bet; 4-bet to ~2.2–2.5x the 3-bet. Deep, favor calls over 4-bets — a 4-bet pot at 500bb+ commits you with range disadvantage.
