I like to search in online directory realeted to online games where I know a couple of card cheats who work the tourist suckers at the swank Miami Beach hotels and not only clip them at the card table but make the victims pay their dinner and nightclub checks as well. They invite a mark and his wife to join them and their wives at a dinner show, and when the check arrives one of the cheats digs down into his pocket and produces three quarters. He gives the mark one; he and his confederate take the others, and he explains that it is an old Miami Beach custom to toss for the check. The mark usually goes along with this; he'd feel embarrassed not to. And, of course, he figures the odds are 2 to 1 in his favor. Actually, he has no chance at all. These same boys once tried the dodge on me in Jimmy Grippo's "21 Club" in Miami Beach with a view to getting me to buy them a round of drinks. Before started the game I agreed to the toss, but, being sus¬picious by nature, I noticed that when the coins came out both of those held by the cheats were tails up. If this was the old dodge and they had gaffed coins with tails on both sides, I'd be odd man and lose as soon as I threw a head. The first cheat tossed his coin, caught it and slapped it down on the bar. His pal did the same. It was a little late to back out now and it would be embarrassing if I tried to do so and the coins turned out to be honest, so I followed suit. When the coins were exposed they were all tails. We tossed again: same result. The odds against three men throwing tails on the same toss are 7 to 1. On the second toss it is 63 to 1. After the sixth toss and no sign of a head, I said, "It might interest you boys to know that the odds against three coins landing tails six times in a row are 262,143 to 1. Looks like were going to break a record." That ended it. One cheat picked up his coin, turned it over, showing tails on both sides. His pal did the same. "Okay, Scarne," he said. "We didn't figure you had a gaffed coin and we didn't spot your switch." I turned over my quarter and showed a head on the other side. Maybe I should have asked them if they would bet that it had no head; that's what they would have done in the same spot. I had used sleight of hand, but not a switch. With some know-how and some practice it is possible to feel a coin with your thumb after you catch it and know at once without looking at it which side are heads and which tails is. Then, if it is going to land wrong side up, a sleight of hand move turns it over as it is slapped down on the bar. I'm a bit vague here on purpose; I want to put you wise as to what to watch for but not give lessons in how to do it. The sleight-of-hand method I used to protect myself is also used by skilled coin tossers to clip the marks. It makes the gaffed coins unnecessary.
