the use of a gaffed dealing shoe, an expert card mechanic can do it with a regular dealing shoe as well. The practice of using a burn card developed to help prevent this method of cheating. When burn cards are used, the top card is always discarded and the second one dealt. This is intended to prevent the dealer from gaining information about the next card to be dealt, since the second card is concealed by the top. Ironically, the second deal can be used to discard the second card from the pack and deal the original first. The design of the back of the card can either help or hinder second dealing. A playing deck with only a solid color back makes second dealing very difficult to detect. Less so are cards with a uniform pattern or a single logo, such as an airline promotional pack. Easiest to detect are cards with a strong white border design, which appears stationary on the top card as the second card is slid out from underneath. The second deal can be performed using either one or two hands, and also from a tabled deck, again using one or two hands. The practice of using the dealing hand in such a way that disguises the deal is known as 'using shade'. The practice of tilting the deck to help provide 'shade' is known as a 'necktie'. Tells on the second deal include changes in pace when a second is made, variations in the dealing card noise on a second, strange deck movements when dealing a second, or odd finger movements. Odd grips are sometimes employed, which can suggest someone is not dealing honestly. See also Bottom dealing Cheating at poker Card marking Notes References John Nevil Maskelyne, Sharps and Flats.
