Game: 6-max NLHE | Format: Cash | Blinds/Antes: 1/2 | Effective Stacks: 100 bb | Hero Position: BTN | Pot Size: 3.5 bb (CO opens to 2.5 bb). Hero holds AJo on the Button facing a Cutoff open. Why is AJo considered a poor candidate for a cold-call in this scenario?

1. Hero has 52% raw equity against the CO range, which is below the threshold for a profitable call.
2. An Ace-high hand is too strong to call and must be turned into a 3-bet bluff to maximize fold equity.
3. Hero must defend at least MDF = 80% of their range to prevent CO from auto-profiting with any two cards.
4. Its diffuse equity makes it vulnerable to domination in pots that frequently go multiway.
