The Cards

While you can play with any fifty-two-card deck, a stickler for details will tell you that standard poker cards are three and a half by two and a half inches. Fortunately, unless you grew up in a house with a bridge parlor, poker cards are what you have always considered to be a normal deck. (The deck used for bridge, a game where you have to hold a lot of cards at once, is a little narrower.)
