Behind the scenes

 * Holdout is a term for concealing and hiding cards on one's body.
 * Additionally, a 'holdout gun' is another name used to refer to a pocket-pistol or derringer: handguns of very small size and calibre, making them easy to conceal, and meant to be used in emergencies or situations where conventional weapons are inaccessible.
