The more that comes out about this story, the more that I'm convinced the casino was freerolling Ivey. The casino staff were clearly watching the game closely and they would've recognised what was going on.
The only reason I can see for them allowing the game to continue is that they figured they'd get to keep Ivey's money if (despite his edge) he still lost and if he won, they'd just go to the tapes, point out that he was edge sorting and withhold his money.
On the flipside, Ivey is no casino novice and he'd have to know all of the above - he'd
have to know that the casino would see straight through what he was doing. He'd know that
casinos aren't in the habit of allowing people who advantage play them to keep their winnings.
So what's really got me wondering is how he thought he'd be able to get away with it... in a lot of ways it seems Ivey and the casino were actually metagaming each other over the course of this session.
Ivey would never have to cheat. But he's a pro and no stupid enough to pass up on a huge +ev spot when he sees it.
FYP.
It's debatable whether what he did was actually cheating - after all, he never actually touched the cards, all he and his companion did was look at them. It was the casino employees that arranged the deck to his liking and
let him keep playing with that deck.
