Double-Ace Flush poker
In draw poker, a flush topped by an ace and a joker. In some
clubs, such a flush used to
rank higher than any other flush, but that is not very common.
For example, ace-joker-10-8-7 of
clubs is equivalent in most card rooms to A-K-10-8-7 and does
not beat A-K-Q-9-7 of hearts; in
some clubs, though, it used to. Even though this is not a ranking
hand in most clubs, you still hear the term applied to a flush
with an ace and a joker in it.
