Have an ace to play
Meaning
To possess a crucial advantage or a secret plan that can be used at the right time.
Origin
The imagery of "having an ace to play" comes directly from card games, particularly those where an ace holds the highest value, such as poker. In the tense atmosphere of a card table, holding an ace means possessing a powerful, often winning, card that can turn the tide of a game. The true power of the ace, however, is not just in having it, but in knowing when and how to "play" it—to reveal it at the most strategic moment to secure a victory. This strategic deployment of a hidden advantage moved from the gambling halls to everyday language, describing any situation where one possesses a secret, decisive asset ready to be unveiled.
Examples
- Despite trailing for most of the game, the coach knew he still had an ace to play with his star striker waiting on the bench.
- The CEO assured investors not to worry, hinting that the company had an ace to play in the upcoming market changes.
