One of the world's top poker players, Phil Ivey, has lost a Supreme Court bid to reclaim £7.7m of winnings withheld by a London casino for five years.
The American was challenging a Court of Appeal judgement that Crockfords Club could refuse to pay up when Ivey won the cash playing card game punto banco.
The club said Mr Ivey had broken its rules by using an "edge-sorting" technique to spot advantageous cards.
Mr Ivey had consistently argued that he had merely used a legitimate advantage.
