ATLANTIC CITY, N.J. (AP) — An Atlantic City casino is suing a big-time gambler, claiming he won $9.6 million in a card-cheating scheme.

The Borgata filed a federal lawsuit Tuesday against Phillip Ivey Jr.

The suit alleges Ivey and an associate exploited a defect in cards made by a Kansas City manufacturer that enabled them to sort and arrange so-called “good cards” and gave him an unfair advantage in baccarat.

The casino claims the technique, called “edge sorting,” violates New Jersey casino gambling regulations.

Ivey didn’t immediately respond to a message sent to his Twitter account Friday. A message left with a lawyer who previously represented Ivey wasn’t immediately returned. Ivey’s website did not include a contact email or a phone number.

Ivey is renowned for his poker playing, considered one of the best worldwide.
