The math on card counting has changed over the years.
I don’t mean the raw numbers governing the true count, or the edge when you’re at +4 and doubling a 10 against a 6.
I mean that a good card counter will need to avoid detection for hundreds of hours in order to be profitable, but I only need to catch them once.
In today’s technological world, I can have a description, name, and facial scan sent to a dozen surrounding properties before a good card counter can even be escorted from the building.
Make a mistake once in some Indian casino in Oklahoma and the odds are good you won’t even make it to a table without being escorted out the next time you arrive in Las Vegas.
This ups the stakes because once you’re flagged for the first time, you will have a much harder time going unnoticed in the future. It may even bring your playing days to an end.
Casinos around the country subscribe to various databases and programs that help them manage counters and other advantage players.
That shared information means one misstep for a card counter can be extremely costly.
How Casinos Catch Counters
BOLOs (Be On The Look Out) or info sheets on players will not only have pictures, often from multiple angles, but also known associates and aliases.
It will have a detailed description and other identifying info like tattoos.
Many casinos use Car Tag Readers to let them know when certain VIP guests arrive or just to keep track of who enters and exits the garage or parking area, so don’t be surprised if some of that data is also on file.
Typically, these are sent out regionally, or to casinos that have information-sharing agreements between their surveillance departments, but the info is still widely available to be searched by name, description, or the like by any casino that subscribes to the databases.
All of this 온라인바카라 is often combined with facial recognition software which means many known counters are unlikely to even make it to a table before management intervenes and asks them to leave.
Most casinos will simply not take a chance on letting someone identified by another casino as a card counter play on their tables, though some will allow a player a little leeway so that they can make their own determination.
In the medium to large casinos I’ve worked, it’s not unusual to walk three or four counters a week off the property.
I’m sure the number is much, much higher at certain Las Vegas properties known for their advantageous rules, and deck penetration.
Literally four out of five of those I walk off the casino floor will have been identified off a BOLO. They messed up once and now we have got them again.
But the fact of the matter is, counting cards is a mathematical game. You can only change your play so much before it erodes all your profit.
Some ways of playing are unavoidable.
