Five-card stud is the earliest form of the card game stud poker, originating during the American Civil War,[1] but is less commonly played today than many other more popular poker games. It is still a popular game in parts of the world, especially in Finland where a specific variant of five-card stud called Sökö (also known as Canadian stud or Scandinavian stud) is played.[2] The word sökö is also used for checking in Finland ("I check" = "minä sökötän").
The description below assumes that one is familiar with the general game play of poker, and with hand values (both high and low variations). The description also makes no assumptions about what betting structure is used. Five-card stud is sometimes played no limit and pot limit, though fixed limit and spread limit games are common (with higher limits in the later betting rounds). It is typical to use a small ante and a bring-in.
