Phil Ivey case: What is 'edge-sorting'?

Top poker player Phil Ivey has lost a case to reclaim £7.7m in winnings from a London casino.

The case centred on the technique of 'edge-sorting' which Mr Ivey had used to help him in the game.

The player insisted it was a "legitimate strategy" to exploit the casino's failure to protect themselves against top players such as himself.

Essentially the technique involves working out the value of a card by spotting small differences in the patterns on the back of the card.
