英文[出皇牌]點寫

皇牌是 TRUMP CARDS
e.g. He plays a trump card ..... or simply..... he plays his trumps

Trump 也可作為動詞。如果玩橋牌，his 'diamond king' was trumped 即是他的方塊King被人家的皇牌吃掉了。

如果你說出皇牌〉只是一個比喻，則可加 by 在後面....
e.g. He finally plays his trump by showing them the evidence, a confidential note issued by the Director. 他終於使出皇牌，拿出董事長的密函來作為證據。
