To work this hold out the hook at the end of the cord is fastened to the loop of the shoe on the opposite foot. When the feet are spread apart the act causes the cord to draw the clamp referred to down through the sideway and to the near end of the sleeve. Any cards that are in it will reach into the palm of the hand, where they can be taken out or placed back into the clamp. By drawing the feet together again the cord relaxes, and the elastic will draw the clamp and the cards it contains back up the slideway to its place near the elbow. There are other similar hold-outs. Don't let them hold you up. MARKED CARDS. Marked cards are known among gamblers as "Paper," and are considered an article of utility in draw poker. The dealer, should he be a second dealer, will deal second to himself instead of reading the hand of his opponent's, thus giving himself a pair, two pair, threes or whatever he wishes. Marked cards are used by those who are not second dealers, as they are often able to fill a hand by holding a card in the hand to correspond to the card on the top of the pack, and in any case enabled to read opponent's hands and play accordingly. They are perhaps the greatest advantage to a professional second dealer, as by drawing a bob-tail card of any kind he can spoil the chances of an honest player, however, skillful. People at large are becoming aware of many of the schemes used in swindling, but so fast as the public becomes acquainted with a scheme, the shark invents something to take its place or practices the old one until he has it so fine under his manipulation it is hardly recognizable. A professional gambler is soon known. Even if he is never detected cheating, he is given credit for it. [Illustration: Caught Working the Sleeve Hold-out.] [Illustration: FIG. 31.
