This. A previous article stated that Ivey and his friend talked the dealer into rotating some cards (6s 7s 8s and 9s) prior to the first shuffle.

I don't think any dealer or casino would agree to a total re-orientation before the first shuffle/game.

My impression from prior coverage was that the rotation occurred as the cards were revealed during play, so that on each next shoe, more and more (potentially all ) of the intended cards were reversed.

  • The way dlss suggests is the safest and most sensible way.

    Usually you'll start play by breaking the seal on new decks which will be fanned out to check them: it's effective and efficient to get the dealer to turn a few sequences of cards here while they're still in the right order.

    Otherwise, you have a lot more work to convince the dealer to rotate the cards one-by-one: "rotate that 9 of clubs, not the other 9 of clubs" is way more suspicious.

    Having said that, it is a bit surprising that "dealer collusion" spidey-senses were not tingling. This is the first thing that casinos should watch out for. Maybe they realised something was going on but couldn't figure out what, or how it would be effective, in time.

    • Sure, if the dealer/pit agrees, that'd be the best way... it just seems even more blatant, and the idea the casino would comply even more outlandish.

      Whereas, making requests during the game, that seem a bit erratic (or triggered by in-round results, like "let's flip that one so it doesn't burn me again!"), seem like they might escape scrutiny longer.

    • Cards almost always come pre-shuffled in the packs that casinos use for baccarat.

Can you link me a source to that article? Phil Ivey is perhaps the greatest living card player in the world. Do not underestimate the near autistic savant level of perception and mental capacity that he and other genius card players have. I can imagine Ivey still being able to gain an exploitable edge merely by simply recognizing the direction in which specific cards are returned into the deck.

  • "The lawsuit claims that Ivey and his companion instructed a dealer to flip cards in particular ways, depending on whether it was a desirable card in baccarat. The numbers 6, 7, 8 and 9 are considered good cards" from the article linked by https://news.ycombinator.com/item?id=7580399

    FWIW I think almost anyone could gain an exploitable edge by recognizing the direction in which specific cards are returned into the deck if they took it seriously and practiced... it just sounds like a lot of work, and a way smaller edge. I personally think it's more impressive that he socially engineered the dealer.

    It's kind of like "good artists copy, great artists steal" only for statistical edges. maybe "good gamblers work hard for an edge, great gamblers have an edge before they sit down"

    • Yeah, this is extremely interesting to me either way. By knowing which way only one card is facing, you still tilt the deck in your favor ever so slightly. After using the same deck over multiple rounds, I assume you tilt the edge in your favor significantly without even having to give directions on specific cards. It would add to the casino's case for them to argue that he manipulated the dealer to make it seem more akin to an inside job, but I can see how Ivey could gain a significant advantage without even needing any "social engineering."

      "it just sounds like a lot of work, and a way smaller edge." If you read Ben Meizrich's Bringing Down the House, you wouldn't believe the degree to which these guys work to get an advantage over the house. There's a part in the book where he talks about how members of the MIT Black Jack Team so thoroughly practiced cutting a deck that they were able to cut stack of decks exactly 52 cards from the bottom. A seemingly improbable feat to do regularly but one that they perfected to the point that it became an integral part of their strategy.

  • Naturally, they are returned in a uniform manner. To get any rotation (for edge differentiation) would require the ability to handle the cards (which he did not have) or the ability to convince someone to rotate cards (which is what it is alleged they did).

    Additionally, Phil Ivey is an astonishingly good poker player (20M+ club, 8 braclets), but is known more as a degen on other games.
