Phil Ivey

Pro poker player Phil Ivey just lost out on some major winnings, after a British casino won a case that ruled it didn’t have to pay him millions he was owed.

According to ESPN.com, the ten-time World Series of Poker winner had been in court with Genting Casinos UK over 7.7 million pounds ($12.4 million) in winnings. The casino’s lawyers accused him of¬†using of “edge sorting” tactics, which the casino¬†argued was not legitimate and shouldn’t have to pay. Apparently, Britain’s High Court agreed.

The casino said Ivey was keeping track of card values by watching for design imperfections on the backs of the cards.

The professional gambler said, in a statement, that he was disappointed with the ruling.

“As I said in court, it’s not in my nature to cheat — and I would never do anything to risk my reputation,” Ivey said. “I am pleased that the judge acknowledged in court that I was a truthful witness by saying that, ‘I am entirely convinced that Mr. Ivey did not consider that what he was doing was cheating.’

“I believe that what we did was a legitimate strategy — we did nothing more than exploit Crockfords’ failures to take proper steps to protect themselves against a player of my ability — clearly today, the judge did not agree.”

Ivey said he won the money during two days of playing baccarat at Crockfords, a Mayfair casino part of the Genting group, in August 2012.

He’s currently in a similar legal battle with the Borgata Casino in New Jersey. Borgata is suing Ivey for the $9.6 million he won using the same controversial edge-sorting technique while playing mini-baccarat in 2012. Depositions are expected to continue until July 2015.

Edge-sorting is a technique in which players use flaws in the designs on backs of cards to identify them in advance.
