dbo:abstract
- Edge sorting is a technique used in advantage gambling where a player determines whether a face-down playing card is likely to be low or high at casino table games by observing, learning, and exploiting subtle unintentional differences on the backs of the cards being dealt. Applied by poker player Phil Ivey and subsequently challenged in court by the casino in which he did so, the England and Wales High Court and Court of Appeal and the UK Supreme Court ruled that the technique, which requires the player to trick the dealer into rotating specific, high-value cards, is cheating in civil law, and that a casino was justified in refusing payment of winnings. This ruling would not be applicable if the player simply took advantage of an observed error or anomaly in the deck for which he was not responsible. (en)
