Phil Ivey a professional poker player lost his appeal that was made against a casino of London.
The appeal was about £7.7 million and he lost it because of the use of “edge-sorting”. It is a gambling technique and it involves exploitation of card design irregularities that is there on back of card.
Phil Ivey played baccarat alias Punto Banco at Crockfords club in Mayfair. After finishing the tournament, Ivey was told to go back home and his winning amount will be sent soon. Ivey waits to get winning amount, but that never came. Instead, he got his stake amount of £1m back. In 2014, High Court dismissed his appeal, saying that, there was irregularity found in winning of the game.
Genting the casino operator on the appeal said ‘Ivey used edge-sorting technique to get an advantage and it is not a legitimate strategy and casino does not own any liability for same.”
Edge-sorting is a tactic that allows players to predict a card whether it is high or low. It can be done by finding tiny irregularity at the back of the card. The difference is because of manufacturing defects and some deck of the casino had these types of cards. The irregularity can be broken ring, half circle at the edge of the card etc.
Ivey took advantage of these minor irregularities and won the game. Casino says “Ivey exploits this manufacturing defect and thus breach the gaming contract.”
The court of appeal, Lady Justice Arden said on the occasion that, it was breach of game contract and thus dismissed the hearing of Ivey.
“It is not like a casino intentionally place defected card at the deck. It is not a defect, but it is a minor change that is acceptable up to 0.3mm” said manufacturer of cards at casino.
