Best Flush poker
A form of draw poker found only in home games, in which only
flushes win. If there are more than one flush, the best one
wins, exactly as if two or more flushes were competing in an
ordinary game. If there is only one five-card flush, that hand
wins.
If there are no flushes, then the best four-card flush wins.
If there are no four-card flushes, then the best three-card
flush wins. Rarely, the best two-card flush wins.
