Poker Bot Leads Professional Card Players Through 20 Percent Of Hands

Poker Pros Down About 1,600 Big Blinds


The humans held steady over the weekend, but still trail the poker-playing machine Libratus.

The 20-day contest at Rivers Casino Pittsburgh features Jason “PremiumWhey” Les, Dong “Donger Kim” Kim, Daniel “Dougiedan678” McAulay and Jimmy “ForTheSwaRMm” Chou each playing heads-up matches versus Carnegie Mellon University’s world-class AI.

Through Sunday, about 23,000 of the scheduled 120,000 had been played, with the humans down 159,000 play-money chips. The blinds stay at 50-100.

The 1,600 big blind deficit is actually not enough to truly say the humans are losing, according to computer scientists involved with the project.

via CMU.eduIn 2015, Les, Kim, Dough Polk and Bjorn Li finished up 732,000 chips after 80,000 hands against an earlier version of the bot, but Carnegie Mellon computer scientist Tuomas Sandholm said it was a “statistical tie.”

The poker pros are playing about eight hours a day beginning at 11 a.m. local time in Pittsburg. The Twitch live streams of “Brains Vs. Artificial Intelligence: Upping the Ante" are available here.
