Shameful actions by a supposedly upright citizen of the gambling world. As far as his guilt, makes no matter his defense, this is the second incidence of such behavior leaving little to no chance of him being totally innocent.
Here's the thing - Ivey is an unashamed advantage player. Casinos know this and they let him play anyway because they want to be the ones to take his money when he loses.
What he's done here isn't really that different to sitting down at a poker table with someone that he knows he's much better than (which, when you're Ivey, is pretty much everyone). He found an edge and he exploited it.
In my opinion, if he used flaws to read cards, that is not cheating. If he had actually marked the cards, that would be another matter. But to use flaws already there? I am anxious to see the outcome of this case. There may be a grey area here, in that somehow he and a friend talked the dealer into dealing them a certain way. Hmmmm, shouldn't the casino have rules for the way the cards are dealt? So I am unsure of what that can mean. This was in mini-baccarat. Seems to me that if his eyes are good enough to see these flaws, he could make a lot more at black jack.
That's very much the question here: is advantage playing the same thing as cheating? Especially when the casino staff were the ones turning the cards and arranging them for him.
My personal opinion is that the casino left themselves open to this as soon as they let him continue to play. They jump all over the average
blackjack card counter, and Ivey's behaviour in these games shouldn't have been hard to spot either. If they spotted it
and let him continue to play then it's basically their own fault if they went on to lose money. If they didn't recognise it, or didn't implement procedures to negate the advantage... then they need to fire their game security team and hire ones who know what they're doing.
Seriously, this is a pretty easy advantage for the casino to negate: all they have to do is include a turn in their shuffle procedure. Turn half the cards around when you're shuffling, and then the edge sorter can't reliably tell which cards are good and which aren't. The system
only works if the casino keeps the cards oriented the exact same way at all times - which is why Ivey was specific about using a shuffling machine etc.
As to why he played baccarat instead of blackjack, who knows. It might be that they only had the flawed cards on the baccarat tables, not the blackjack ones. It might be that blackjack had a shuffle routine that negated the edge sorting. It might be that security is better at picking up advantage play / cheating on blackjack.
I suspect it's probably just easier to apply the advantage on baccarat though. Edge sorting, at best, only lets you get a read on the first card in the shoe. You either like the first card or you don't, and adjust your bet accordingly. Then the hand plays itself and you're onto the next one very quickly, no messing about with decisions about hitting/splitting/doubling or having to count cards or anything.
