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.

    > also important to note they made the players play thousands of hands over weeks To your point, I wonder how they account for mental and physical fatigue. To a computer it makes no difference to play thousands of hands over such a long period of time or hundreds of hands over the course of a single day. Humans on the other hand don't have the same attention span as a computer.

      not to mention that people play differently with fake money than real money.

  That's both an unfair slight to the ethics of the researchers involved, as well as inaccurate. They've published in advance their criteria for declaring a victory vs a tie: http://www.cardplayer.com/poker-news/21215-poker-bot-doubles-lead-in-historic-match-against-humans http://www.cardplayer.com/poker-news/21215-poker-bot-doubles... which is: "If after 120,000 hands either Libratus or the humans are one standard deviation above break-even, they will have won the competition with “statistical significance.”" (I'm a professor at CMU, but I have nothing to do with this research or competition.)

    we mostly mean by the media. Story if they barely lose "Poker bot statistically ties pros". Story if they are one chip up: "Poker bot leads/beats pros"

    One standard deviation is not enough to declare that one strategy is better than another.
