在自己没有好牌而对方又可能有同花顺的情况下，光靠手中的一张A大大地提高赌注，讓对方相信自己有更好的一手牌。

"When 3 cards to a flush are showing on the community card board in Omaha, a player with 2 cards of that suit in their hand can make a flush using the all-important '2 and 3' combination. If you have only one card of this suit you can not make a flush even if a 4th card appears on the board. However if that card is the ace of the suit in question then you have a powerful piece of knowledge - any flush that your opponent holds is not the 'nut flush'.

The 'bare ace bluff' uses this information to make a huge raise, representing the made 'nut flush' in an attempt to get opponents to fold. In pot-limit Omaha this is often made on the turn or after some raises on the flop - the ideal being that you can bet enough chips to put considerable pressure on your opponent(s)."

nut flush: 当抽得得一张牌可以使你凑成可能出现得的最好的同花

我就之前的翻译更正一下，不是“同花顺”，而是“同花”，因此改为“在自己没有好牌而对方又可能有同花的情况下，光靠手中的一张A大大地提高赌注，讓对方相信自己有更好的一手牌。” wenger提议的“亮A唬人”作为名称很好，简洁明了。
