The jack or knave is a playing card with a picture of a young man on it. The usual rank of a jack is as if it were an 11 (that is, below the queen and above the 10) although in some games - such as Blackjack - it is equal to a 10. However, jacks are the highest possible cards in the German game Skat, and are lower than 10s in many other games, like Pinochle. In some countries/cultures, the jack is ranked above the queen.
