Phil Ivey did the same edge sorting thing at a casino in London and lost the ensuing court case https://www.theguardian.com/law/2017/oct/25/poker-player-phi... . It was a very important case because it found (as I understand it) that he was cheating even though he had not been intentionally dishonest or done anything against the rules of the game.

It's an interesting and bizzare situation. Firstly baccarrat (In my understanding) allows the player to have assistance from others in a way that other card games eg Poker do not. In poker there is an explicit "one player one hand" rule generally (online you are often allowed to "multitable" but you're still playing one hand on each table at a time). Allowing this sort of assistance from others counting the cards etc seems like it opens the door to various sorts of things that would be considered cheating in other games.

Secondly it's weird that the stakes are so high and yet the casinos can't seem to get decks of cards which have precisely the same pattern printed on the back of every card. It sort of blows my mind that that's an issue.
