With the advent of AI bots in Poker, Chess etc., what happens to the old adage of "Play the player, not the game". How do modern human players manage when you don't have the psychological aspects of the game to work with? I see on chess channels that grand masters have to rethink their whole game preparation methodology to cope with the "Alpha Zero" oddities that have now been introduced into this ancient game. They…

How many games did the bot beat the same 5 players? And how many games were played?

We played 10,000 hands of poker in the 5 humans + 1 AI experiment. The number of hands won isn't a useful metric in poker. If you win only 10% of your hands and make $1,000 on those hands, while losing only $1 on the other 90% of hands, then you're a winning player. The bot won at a rate of 4.8 bb/100 ($4.8 per hand if the blinds are $50/$100). This is considered a large win rate by professionals.

> This is considered a large win rate by professionals. It depends on context. 4.8bb/100 is quite good for high-level online play, but wouldn't be enough to make a living at live poker. The biggest game that runs on a regular basis in most areas is $5/10. At ~33 hands per hour, that's 1.6bb or $16 an hour. And I'd assume there was no rake in your game? That would take a big chunk out of the rate.

I would love to get a hands on the source. Hook it up to an API like https://pokr.live and then basically build a computer vision poker bot. The trick is how to create natural mouse click movements or keyboard inputs. This is the part that I'm most shaky on but the pokr.live API works by sending screenshots which it will translate into player actions at the table disclaimer: pokr.live API is a WIP

So will this be the end of online poker?

No, having losing odds never stopped anyone from gambling.
