An ace in the hole
Meaning
A hidden advantage or secret resource that can be used at a crucial moment.
Origin
In the game of Five-card stud poker, players are dealt one card face down, known as the 'hole' card, with subsequent cards dealt face up. An 'ace in the hole' literally means a powerful ace concealed from opponents, giving the player a significant, secret advantage. This phrase perfectly captures the strategic tension and excitement of holding a hidden asset that can turn the tide of a game, and by extension, any situation where one possesses an unseen, winning edge.
Examples
- She kept her ace in the hole, only revealing her surprise witness when the defense thought they had won.
- Even though the company was struggling, the CEO knew their new product line was an ace in the hole for a comeback.
