U.S. District Court Judge Noel Hillman determined that the pair did not meet their obligation to follow gambling regulations on four occasions in 2012 by having a dealer at the Borgata arrange Baccarat cards so they could tell what kind of card was coming next . . . The Borgata claimed the pair exploited a defect in cards that enabled them to sort and arrange good cards. The casino says the technique, called edge sorting, violates state casino gambling regulations. But Ivey asserts his win was simply the result of skill and good observation.
