The wheel-ace 4-bet bluff earns its keep against the button's steal-heavy 3-bets.
The reference tier. 4-bet a tight value range, call with hands that flop well, fold the rest without ceremony.

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.
