Jacks Back ( poker )



A form of five-card draw poker in which each player in turn looks at his cards, and opens if he has jacks or better
(and if he wishes). If no player opens for high--and to do so he must have at least a pair of jacks
(and he must show openers at some point)--then the hand is played for low (as described under ace-to-five),
again starting with the player to the left of the dealer. At this point, the game becomes bet-or-fold.
