Libratus AI vs poker players - complete destruction over last few days

The 2017 version of Carnegie Mellon University’s poker pro vs. poker bot contest hit the half-way mark yesterday morning and the team represented by real humans is falling behind faster then ever! Check the results at the end of this news!

With 64,000 hands of the 120,000 scheduled played the poker pro team of Jason Les, Dong Kim, Jimmy Chou and Daniel McAulay is down nearly 800,000 chips. That’s 8,000 big blinds. None of the pros is ahead of the machine. The contest is scheduled to end Jan. 30.

Early last week, the humans were showing signs of little comeback after they started breaking even in games, but the machine was having none of that and after some adjustments to the strategy it started to completely destroy the players:
“The bot gets better and better every day,” Chou told CMU. “It’s like a tougher version of us. The first couple of days, we had high hopes. But every time we find a weakness, it learns from us and the weakness disappears the next day.”

Libratus was developed by Tuomas Sandholm, professor of computer science at CMU, and his Ph.D. student, Noam Brown. Libratus is just the latest in a series of poker bots from Sandholm.

According to comments from the human team, this version of the bot adjusted its river play according to previous machines and Libratus will often over-bet shove on the river for either value and as bluffs. While humans show some bias in such a river strategy, the machine has remained balanced and thus pretty unpredictable.

Each night after a session, the Pittsburgh Supercomputing Center’s Bridges computer performs computations to sharpen Libratus’ strategy, especially with regards to the river.

Here are the results:

i'd kill for some HH's from this bot

As far as I know, all of them except Dan Macauley play 50/100. Macauley might too, I just have no idea who he really is.

Maybe this is coming next year, but who will want to play then?

players like isildur, smash some cpu for money?

i'd imagine isildur would be alot weaker than these guys having been on break from nlhu for a long time. I used to play Dan hu at .5/1 5ish years ago, and i saw him at 50/100 2 years ago so he moved up pretty quick.

Cmon dude, its the 3rd or 4th time in a row you post news that are 24hrs old. They won 10bi yesterday, down 70bi in 71k hands resulting in around 10bb/100 loss

There you can see the info up to date.
The guys are complaining about the bot adjusting instantly, when they adjust to him and that they have no means of exploiting him, while he destroys them.

Donger is actually beating the bot, by four buy ins, very close. Seems like if it was just 4 Dongers or people better than Donger then the humans could have a chance vs this bot still. Jason Les and Donger get dealt the same hands vs the bot right?

i was thinking he same. blom could break that bot.

I highly doubt it, the improvement of the bot from the last year is tremendous. Blom could be ahead, but no way to crush it for say more than 20 bb/100.

would be interesting if the bot would win in 6handed games

lots of talking out of the ass

According to https://www.riverscasino.com/pittsburgh/BrainsVsAI/ Donger Kim is up 12.6 buyins in fact, unsure if this is up to date?

Wouldnt change anything for the bot to play real money, would only if anything, play against humans ^^

He was ahead around 4bi yesterday, its 12.6 now yes. Twitch page has the up-to-date results at all times

Ok Dan is dougiedan from stars, he plays the highest HU now after daily grind.

Jason les, like last time, is the fish. Delete him and they would have a much better chance.

They all get the full hand logs with the holecards at the end of the day. Those are private. These 4 players are going to have super strong knowledge of how this GTO bot plays and nobody else (except doug, I expect dong and doug talk and other private groups). I guess it is possible they signed a NDA but who knows, the bot creator said the players asked the HH not be released.


After it is all done, the bot creator is doing a massive QA and will explain a lot

Goodnight, sweet prince

just now Jason said he is done $500k. He makes up close to 60% of the losses.

Les is just getting raped
