A
Jack, also
Knave , is a
playing card which, in traditional French and English decks, pictures a man in the traditional or historic aristocratic dress generally associated with Europe of the 16th or 17th century. The usual rank of a Jack, within its
suit, plays as if it were an 11 (that is, between the 10 and the
Queen). As the lowest face (or "court") card, the Jack often represents a minimum standard — for example, many
poker games require a minimum
hand of a pair of Jacks ("Jacks or better") in order to continue play.
