Humans barely edge computer in Texas Hold 'Em tournament

At a tournament worth $50,000 held earlier this week  at the Association for the Advancement of Artificial Intelligence's annual conference in Vancouver, B.C., poker pros Phil "The Unabomber" Laak and Ali Eslami went up against Polaris, the reigning world champion computer-poker program.

The two poker pros were sat in different rooms, where each sat in front of a laptop to play Texas Hold ‘Em. The competition featured four matches, 500 hands each, between Polaris and the two poker playing professionals.

At the end of the first round, Polaris had a slightly higher chip count, though the total winnings difference was so small that the round was considered a draw (due to statistical variation). The second round – and the last for Monday – went in strong favor to Polaris.

The humans made a comeback the next day. At the end of the two day showdown, the two poker players came out $570 ahead – just enough to claim a small victory over the computer program.

"I really am happy it's over," said Eslami. "I'm surprised we won.... it's already so good it will be tough to beat in future."

The programmers behind Polaris used several different programs throughout its poker play to test which would be most effective. Phil Laak described one named Mr. Pink as a "careful, reasonable, disciplined, thoughtful player," while he called another one named Agent Orange as being "like a crazed, cocaine-driven maniac with an ax."

"The subtlety to the whole thing is, we won, not by a significant amount, and the bots are closing in," Laak told MSNBC. "That's the true summary."

Considering how small a test this was, it could easily be said that either side won because of luck.

The same cards were dealt simultaneously in both matches to ensure luck was not an issue.

I.e., if the computer was dealt AA against Laak's KK in their hand #1, then Eslami was dealt AA vs. the computer's AA when he played HIS first hand.

2000 hands (500 per round x 4 rounds) isn't a huge amount, but it's certainly not a "small" test.

I'm pretty sure that second part should have a KK in there. I'm guessing after "computer's."

Since the end victory was for the 2 poker players over the several artificial poker personalities, I think a statistical breakdown of each personality vs each player would be much more appropriate than just saying the humans won $570.

Anyway, since $570 is likely far less than the pot for any given hand, I don't think this can be taken as any evidence for pro poker players remaining better than computers.
