Phil Ivey is a professional gambler. He has won nine World Series of Poker bracelets. He has won multiple high-stakes poker tournaments and is widely regarded as one of the finest poker minds of his era.
In 2012, Ivey was also a man who played baccarat at the Borgata casino in Atlantic City. During that time, he won approximately ten million dollars.
The casino later sued him. Here is why.
The Technique
Baccarat cards are printed with a pattern on their back. The pattern is meant to be uniform: every card has the identical back pattern. This prevents dealers from identifying cards by looking at the back.
However, casino printing is not perfect. There are occasionally slight variations in the print alignment. A ten might be printed with slightly different registration than a nine. These variations are invisible to the naked eye but visible to someone who knows what they are looking for.
Ivey worked with a baccarat dealer who could distinguish cards by their back prints. During a seven-hour session, Ivey and this dealer conspired. The dealer would subtly orient high cards and low cards differently in the shoe. Ivey would observe these orientations and adjust his bets accordingly.
Ivey was not counting cards; he was not doing anything that explicitly violated the rules of baccarat. He was simply observing information that the casino had inadvertently provided.
The Borgata Case
The Borgata eventually discovered Ivey's technique (using video review) and sued to recover the ten million dollars. The case went to trial.
Ivey's defense was simple: "I used information that was publicly available. The cards were visible to everyone. If the casino had printed their cards better, I could not have done this. This is not my fault."
The court's response was essentially: "The casino's responsibility is to provide a fair game. You exploited an imperfection in the casino's equipment. While technically not illegal, it violates the spirit of the game. We are requiring you to return the money."
Ivey won at the initial trial but lost on appeal. He has continued to fight the case and has also been sued by Crockfords Casino in London under similar circumstances.
What It Reveals
The edge-sorting case is interesting because it occupies an ambiguous zone. Ivey did not cheat (he did not conceal anything or break explicit rules). But he did exploit a failure in the casino's quality control.
Casinos have a responsibility to provide fair games using properly manufactured equipment. If that equipment fails, and a player exploits that failure, where does the liability lie?
Legally and ethically, courts have decided: it lies with the casino. The casino manufactures the cards. The casino is responsible for ensuring they are sufficiently uniform. If the casino fails and a player notices and exploits this failure, the casino must eat the loss.
From the casino's perspective, this is a tough position. They cannot sue the equipment manufacturer (the manufacturer claims specifications were met). They cannot hold the player liable (there was no cheating). They are simply out ten million dollars.
The Larger Implication
Ivey's cases have made casinos much more rigorous about card and equipment inspection. All major casinos now use computer vision to examine card backs for variations. The industry has tightened.
But the cases also raised a philosophical question: when does exploiting imperfect equipment become cheating?
Most observers regard Ivey as a brilliant player who noticed something nobody else noticed. Some regard him as a cheat who exploited equipment failure. The truth is probably that he was both: brilliant and opportunistic.
As a sportswriter, I have always believed that the player has no obligation to protect the house from their own negligence. But courts have disagreed. In the world of high-stakes gambling, the casino's protection of the game's integrity trumps the player's right to exploit negligence.
Ivey remains one of the finest players of his generation. But he will also be remembered as the man who found the edges in baccarat and paid for finding them.
