“Ace in the Hole”
💭 Meaning
“Ace in the hole” refers to a hidden advantage or resource kept in reserve until it's needed most, i.e., something powerful you don't reveal until the critical moment.
✍️ Examples

📜 Origin
The phrase comes from a variation of stud poker where one card is dealt face-down (the “hole card") and the rest face-up. If that hidden card was an ace, it gave the player a secret, often decisive advantage over opponents who could see everyone else's cards but not that one. By the early 20th century, Americans had extended the phrase beyond the poker table to mean any secret advantage held in reserve.
