This is a great achievement in AI, don't get me wrong, but the headline should read, "AI beats the best four poker players we could find who were willing to play for a mere $200K".
All the actual best players play for millions and have a reputation to uphold. They would never agree to do this.
They four guys they got are pretty good, and could certainly destroy me, but they aren't the best of the best.
I'd love to see the bot play in the World Series of Poker for a few million.
