Call with everything that can flop the nuts; surrender the rest. The button's position is real, but so are your implied odds.
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?
The button 3-bets your hijack open — its favorite move with its favorite weapon, position.
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.
