ace in the hole 秘密武器
A hidden advantage or resource kept in reserve until needed. The term comes from stud poker, where each player is dealt one card face down--the so-called hole card--and the rest face up. Should the hole card be an ace, the player has a hidden advantage. Hole here simply means "a hiding place." In the 19th-century American West, the expression was used to refer to a hidden weapon, such as a gun concealed in a shoulder holster. By the 1920s it had become a metaphor for any surprise advantage or leverage.
Note:
ace in the hole的意思是潛在的或者被隱藏的好處。來(lái)源于一種撲克游戲，玩家有一張牌正面朝下，如果它正好是一張A，那就對(duì)玩家有好處。Hole在這里僅僅表示“隱藏的”。 十九世紀(jì)美國(guó)西部用它來(lái)形容隱藏的武器。例如藏在肩袋中的手槍。到十九世紀(jì)二十年代，它漸漸表示所有讓人驚喜的好處或者殺手锏。
例：The prosecutor had an ace in the hole: an eyewitness. 檢舉人有秘密武器（神秘王牌）：目擊者。
