Now would be as good a time to discuss how to count gaps in three-card straight flushes. These hands are a bit of a dilemma, because the standard terminology of poker no longer suffices to describe the possibilities. In the table game, where the only interesting hand is a four-card straight, you have inside straights and outside straights. You should distinguish straights by the number of gaps in the cards you hold. The term gap is more evocative.
Gaps are bad.
After all is said and done, though, the telling characteristic is the number of possible straights you could make with the cards you hold. Thus, in these games, when counting your gaps, you should subtract one for every high card in the three-card straight flush. This greatly reduces the number of hands that need to be listed in the tables. In the wild card machines, you should ignore wild cards for the purposes of counting gaps. In a game where deuces are wild, assume any straight with a deuce simply does not exist.
