In the 80-90 years of the XIX century in the American city of San Francisco lived a world-famous cheat named George Keplinger. Even now he is considered a genius at card cheats. The biography of this man is almost unknown, but he became famous in the world as a player of the highest level. The talents of this man manifested themselves exclusively in one area - the card game. In it he was an ace, a true professional. 

Many years Keplinger devoted to the study of various techniques that helped to beat his partners. Any cheat begins to master his art by studying card feeders. The earliest models of these devices were quite simple - in the cuff of the shirt sleeve hid a box of stained decks of cards. The player could take the deck he needed at any time or put away the unsuitable one in the box. 

The first device, created by Keplinger, allowed the cheat to replace the card deck in the game with his own - another special cards, which was hidden in a clever box, disguised in the clothes. No one around noticed anything, so quickly the forgery was carried out. 

Thanks to his talent and ingenuity, a little later he invented a great device - an advanced card feeder, with the help of which in the hands of the swindler was the card he needed at a particular time. Due to the small size of the device was hidden in a double sleeve specially sewn for the game shirt. At the same time, George could hide an unwanted card using the same mechanism. 

Kemplinger arrived in San Francisco in 1888 and immediately made acquaintance with the elite of the world of hustlers. Local "celebrities" were in full confidence that they got a naive simpleton, which can be easily beaten. Each of them considered himself a great expert in poker and all cheating techniques. But in fact, everything turned out quite wrong. 

Time after time, for many weeks George beat his partners. At first, everyone wrote it off to fortune - lucky, he was always in the hands of the best combinations of cards. No one noticed that the newcomer, calmly holding the cards in front of him, resorted to bluffing. George's cold-blooded behavior at the table did not arouse any suspicion. George became known as the Lucky Dutchman. His unlucky partners were nervous and completely bewildered. 

What ruined Kepplinger was simple greed. And one day the patience of the beaten cheats burst. They decided to unravel at any cost, what is the secret of luck of their new partner and developed a plan to expose the Lucky Dutchman. 

One "beautiful" evening, having waited for the conditional sign, three local hustlers attacked Keplinger. Having carefully examined all of George's clothes, they found a special mechanism he had invented. The exposed cheat was faced with a dilemma: Lynch's trial or making the same devices for each of the attacked cheats. The lust for life won out. Keplinger had to make devices for his opponents. And in a few years Keplinger's apparatus was used by cheats all over the world. 

Production of the device was engaged in dozens of companies, and it began its triumphant march through the casinos and katrana many countries. Although the price of the device was very high - one hundred dollars, its popularity grew every year. The device justified the money spent, bringing its owners huge winnings. The Kepplinger device has been improved many times over the many years of mass production. While the earliest models used the cheat's knees for control, many cheaters now use devices attached to the chest. They are controlled by inhaling and exhaling. 

The device invented by George was called "mechanical hand". It made a sensation in the card world due to its reliability and silence. Having thoroughly studied all previous achievements in cheating, the cheater invented a very clever device. 

The design of the cunning device is maximally simplified. A thin steel clamp, hidden in the sleeve of a shirt, snatched the card (or several) from his hand and pulled it into a double sleeve. The drive was accomplished by a thin cable hidden in the garment, running through a series of tubes and pulleys to the player's knee. To control the "mechanical arm", the player simply had to spread his legs slightly apart, unnoticed by others. 

Keplinger's ingenious invention is still extremely popular with card swindlers, even though 130 years have passed. Thanks to the San Francisco hustler, the art of cheating at cards has reached a whole new level. 

It is easy to draw a conclusion from everything you have read. Do not gamble, especially with strangers!
