Marked cards are often used by professionals in playing seven-up, but the blacklegs do not find them of nearly as great advantage as in many other games. The description of the manner in which they are prepared has already been given in the chapter on poker and need not be here repeated.
TURNING JACK FROM THE BOTTOM.
This is a very common custom with professional gamblers, who, through long practice, have acquired a manual dexterity which virtually defies detection. The first step of the sharper is to place a jack at the bottom of the pack, leaving it in that position while he deals. If his adversary cuts, the cheat “shifts the cut,” in the same manner as at poker, restoring the cards to their original position. Then, after dealing, he places his hands over the deck, in such a way as to conceal it from view. Then, grasping the pack by its outer edge with his right hand, he turns it over on the jack, simultaneously drawing the latter toward the inside, with his left hand, so that it may meet the other cards as they turn over. He all the time imparts a slight upward movement to the pack, which he finally drops upon the table.
Of course, as above explained, by “turning up jack” the dealer scores one. If, now, his opponent begs, the gambler takes occasion surreptitiously to observe the suit of the bottom card. If it happens to be the same as the strongest suit in his own hand, he repeats the trick, turning it for trump, thereby practically placing himself in a position where the chances for winning decidedly preponderate in his favor.
The sharper very commonly selects as the moment for using this stratagem, that period of the game when the score stands six to six, thus scoring the single point necessary to enable him to win.
WHIST.
Whist is too tedious a game for the professional gambler; it is peculiarly a game of skill, and therefore less adapted to cheating purposes, than are many others, the issue of which depends more upon chance. At one time both long and short whist were very popular at evening parties, but neither of them was ever a general game for money in this country, and even as a pastime Euchre has far surpassed it in public favor.
Still, trickery may be employed with telling effect, and the professional blackleg brings his ill-directed skill to bear upon it in a variety of ways.
The chief advantage to be obtained by the deal is with a “second,” and the gambler who is sufficiently dexterous to give the aces, kings and queens to himself and his partner can make the “odd trick” every time he deals.
“Signing up” between partners is also an essential element in fraudulent whist playing. For although each confederate has a general knowledge of the contents of his partner’s hand, yet there are critical periods in the game, especially when one of the two holds uncertain cards, when “signing up” is of great value in determining the event with absolute certainty. This secret telegraphy is arranged beforehand between the pair of swindlers, the signals for “suit” and “size” being mutually agreed upon; and where the understanding is perfect the defeat of any honest players with whom they may be contending, is a moral certainty.
