Please read the actual article, which about a mathematical game using a continuous random distribution. Other than the name, it is very dissimilar to the Casino game.

There are still many Vegas casinos where you get 3/2 odds on blackjack and play with a six deck shoe. Don’t give business to the strip CSM and 6/5 games if you don’t like it.

There's still single and double deck blackjack too. Treasure Island on the strip has double deck and a lot of casinos on Fremont, with El Cortez being my favorite, has single deck. Both are 3/2.

Bally's has the single-deck blackjack going on but if you win too hard someone comes up to you to warn you that you're winning too hard

The Cromwell, mid-strip, has 3/2 odds on its tables. Most tables are 6-8 deck shoes, and I believe there is one or two tables of single deck.

In Vegas in 2021, I was surprised to see double or even (rarely) single 0 roulette tables mostly empty, right next to full triple-0 tables with the same min bet. Players seemed to understand the game too, so I guess the better table had just opened up and they didn't feel like moving.

so even if everything in that paper is VALID mathematically, in reality it will not work because blackjack in casinos is DIFFERENT game then one that is played in this paper.

it‘s a mathematical excursion… it‘s not meant to be a real life applicable thing. read the article before posting please :)

you're right! The article is not about the usual blackjack but a continuous version of the game, however I find interesting to understand this kind of problems. And maybe some day the casinos will start playing this version of the game ;)

The paper isn't claiming anywhere to tell you how to play in casinos.
