It's important to note that last time, the poker players beat CMU's AI by around 500k chips as well and they had the gall to declare it a "statistical tie". Yet if they win by chip they will claim to have "won".

also important to note they made the players play thousands of hands over weeks and many said how they played in a way to shorten the time they had to play. thereby not necessarily showing their "true" skill.

Earlier quoted context omitted.

Why is it unfair? Both the human and computer players are unable to make reads on the other based on physical cues.

If it's unfair in any regard (and I disagree with GP that it's unfair on the merit of physical reads), it's that humans get fatigued and computers do not. Having played poker for stretches of 16+ hours I know that the number of mistakes I make late in the day drastically outnumber the ones I make when I am fresh. And breaks only do so much to counter this fatigue. I'd have to say that playing poker for long stretches…

is at least as what?

Trying to play GTO is an interesting (and very profitable) approach but ultimately it's not the most profitable approach. It makes sense for the AI to be constructed that way because the matches it's likely to play are against good opponents. Most profit in poker comes from playing against not so great opponents though. Against those you usually play extremely exploitable on purpose.

That being said, the AI seems pretty impressive. Not sure how they picked the players I could think of a few HUNL players I'd rather see but they might not be interested in a 200k freeroll.

I played poker part time heads up (one against one) previously and the amount of study and analyses players have to do is huge to only get to a reasonable level.

This challenge is very unfair to players so I wouldn't say it won, players have a massive disadvantage, every professional player has tracking software and a database to analyse every decisions that has been made.

This is of course extremely important because you can model your strategy to exploit the suboptimal decisions made by your opponent, yet players have no access to any of these tools, so the bot adjusts it's play based on their human opponents but humans cannot do the same and are left with a guessing game.

If they want to make a proper challenge then players need to have access to the tools they usually use playing in the Internet.

How would someone with no knowledge of the game learn to play poker? Any good books that stress the mathematical/probabilistic(/game theoretic...?) side of things?

Assuming you at least know the rules of poker, you can probably start with the MIT course on poker theory, available here: https://www.youtube.com/watch?v=OTkq4OsG_Yc&list=PLUl4u3cNGP...

Wonder how long it will be until there is a crowdsourced AI winning the World Series of Poker?

These are heads up matches. The WSOP is 10 handed tables. I would guess the algorithms' skills may not work quite as well in 10 handed play.

Is this really fair? Part of Poker is "reading" when other players are bluffing, it's a lot more challenging to read when a computer is...

Not really. Online poker is much more popular. Plus the computer doesn't have a camera either. You have to deduce if your opponent is bluffing through the plays he/it is making.
