A.I Versus human – how an A.I defeated poker pros.
Publish date: April 7, 2021

There are many people who still believe that poker is gambling. It may be true that there is some element of luck in any card game, but poker is way different.

What better way to prove it than actually showing how collaboration between An artificial intelligence program developed by Carnegie Mellon University and Facebook AI 

They were able to create artificial intelligence that defeated leading professionals in six-player no-limit Texas hold ’em poker, the world’s most popular form of poker.

The difference between a bot and an A.I.
There is a subtle difference between a bot and an A.I.

A bot by definition is a program that runs on specific parameters while an A.I. or artificial intelligence creates independent thinking.

Yes, there are many poker sites that have been plagued by bots. There are bots and they are winning. To deny bots exist is to deny there is a problem.

However, sites like Pokerstars and UPoker have been active in cleaning such problems. There are actual teams dedicated to hunting down these programs and banning them if they are caught.

However, Artificial intelligence is way different. as it can start acting like a human being. sometimes it does go beyond its parameters.

Pluribus – the A.I. that defeated poker champions.
Back in 2019, The AI, called Pluribus, defeated poker professional Darren Elias, who holds the record for most World Poker Tour titles, and Chris “Jesus” Ferguson, winner of six World Series of Poker events. Each pro separately played 5,000 hands of poker against five copies of Pluribus.

In another experiment involving 13 pros, all of whom have won more than $1 million playing poker, Pluribus played five pros at a time for a total of 10,000 hands and again emerged victorious.

Why it matters
Artificial intelligence still relies on logic and mathematical probabilities.

Though poker is an incredibly complicated game, Pluribus made efficient use of computation. AIs that have achieved recent milestones in games have used large numbers of servers and/or farms of GPUs; Libratus used around 15 million core-hours to develop its strategies and, during live gameplay, used 1,400 CPU cores. Pluribus computed its blueprint strategy in eight days using only 12,400 core hours and used just 28 cores during live play.

The fact that it can defeat human professional champions means that any human being can become a champion.

They just have to study more.

Some key elements that helped Pluribus win.
Bet sizing

“There were several plays that humans simply are not making at all, especially relating to its bet sizing. Bots/AI are an important part in the evolution of poker, and it was amazing to have first-hand experience in this large step toward the future.”

Bet sizing is very important in poker. Sometimes that 1 chip could make the difference between your opponent from calling or folding.

Pluribus was able to figure out the comfortable ranges of his opponent which helped him outplay several of his human opponent.

Donk betting.

most human players avoid “donk betting” — that is, ending one round with a call but then starting the next round with a bet. It’s seen as a weak move that usually doesn’t make strategic sense. But Pluribus placed donk bets far more often than the professionals it defeated.

Although most people understand that playing aggressively does help you win. Pluribus actually set it up even further.

It understood its opponents and the probably hands they could have and base its strategy there.

When the probability that your opponent’s hand may not be good plus a good size bet. it became a major advantage.

Playing consistently
Darren Elias, who holds the record for most World Poker Tour titles lost to Pluribus. and this is what he had to say.

“Its major strength is its ability to use mixed strategies,”

As the Pluribus developed more independent thinking. It started using mixed strategies against its opponent.

“That’s the same thing that humans try to do. It’s a matter of execution for humans — to do this in a perfectly random way and to do so consistently. Most people just can’t.”

Conclusion
Pluribus, which is an A.I., that bases its moves on logic and reason, was still able to outplay some of the world’s biggest poker pros.

A computer does not have luck. it just all strategies.

Maybe you are on a losing streak right now. but maybe it is because you need to go back and study more.

You can win, you just have to study and practice.
