In New AI Benchmark, Computer Takes On Four Top Professional Poker Players
HughPickens.com writes: Stephen Jordan reports at the National Monitor that four of the world's greatest poker players are going into battle against a computer program that researchers are calling Claudico in the "Brains Vs. Artificial Intelligence" competition at Rivers Casino in Pittsburgh. Claudico, the first machine program to play heads-up no-limit Texas Hold'em against top human players, will play nearly 20,000 hands with each human poker player over the next two weeks. "Poker is now a benchmark for artificial intelligence research, just as chess once was. It's a game of exceeding complexity that requires a machine to make decisions based on incomplete and often misleading information, thanks to bluffing, slow play and other decoys," says Tuomas Sandholm, developer of the program. "And to win, the machine has to out-smart its human opponents." In total, that will be 1,500 hands played per day until May 8, with just one day off to allow the real-life players to rest.
An earlier version of the software called Tartanian 7 (PDF) was successful in winning the heads-up, no-limit Texas Hold'em category against other computers in July, but Sandholm says that does not necessarily mean it will be able to defeat a human in the complex game. "I think it's a 50-50 proposition," says Sandholm. "My strategy will change more so than when playing against human players," says competitor Doug Polk, widely considered the world's best player, with total live tournament earnings of more than $3.6 million. "I think there will be less hand reading so to speak, and less mind games. In some ways I think it will be nice as I can focus on playing a more pure game, and not have to worry about if he thinks that I think, etc."

But can it make me a sandwich?
I think it's important to note that while we're good at making AI good at one thing, we're still a very long way from making it good at general skills.
not have to worry about if he thinks that I think, etc.
I think he's wrong on this. A computer would still need to consider what his opponent thinks he holds and raise accordingly.
Will the computer be prohibited from counting cards? Humans may bluff, but they cannot fake statistics.
If you are not counting cards, you are playing poker wrong. This is not blackjack with multiple decks.
In Texas Hold 'em, you see your own two cards and the up-to-5 community cards each hand, and the deck is shuffled between hands. Everyone knows what cards have been seen and what have not all the time without any card-counting skill.
I think there will be less hand reading so to speak, and less mind games.
Isn't that what makes the game so interesting? Any good card game involves messing with your opponent's head.
It's poker that's dumb enough to be on TV. If they want a real challenge they should play seven stud.
In fact poker has rules (antes, blinds) where the whole point is to make not playing a losing move.
In a global thermonuclear war, it would be like making unused bombs self detonate in one's country after some time.
Your replies aren't quite making this clear for some reason, but counting cards is a strategy for blackjack, not poker. In poker, the deck is shuffled after each hand, so there is nothing to count. Of course, using whatever information is available to estimate the value of the hands' of your opponents is part of the basic strategy of poker that every sane player, including this computer, uses.
What, are you kidding me? Bluff has him ranked as number 36. That's pretty good, but a far cry from "widely considered the world's best."
I was also confused how this could work in holdem. After some googling it appears that "counting" in poker only refers to certain stud games where hands ahead of you are exposed.
In holdem the only (?) additional info you could have over a competitor is if someone in early position folded and revealed their cards (obviously uncommon). That's info that the small blind wouldn't have had, and could be very useful if you're in late position, especially on the button. But imo that's not really "counting", just gaining info to craft your betting strategy.
Decent answer here:

No, it doesnt depend. All the cards that you have seen are visible to you for the entire hand. Card counting is about remembering statistics about cards that you have seen but are no longer visible.
The guy that you linked to thinks that knowing how many outs you have is "card counting" -- no. you also apparently think so, which means that you cannot possibly have anything to add on this subject (and your ignorance on this subject is not a secret to you, so why are you pretending?)

That site doesn't understand what card counting is. When you count cards, it changes how much you bet on a hand you haven't seen yet. You increase your bet (or enter the game altogether) only when the player odds are higher than normal.
Counting "outs", the number of cards in the desk that will improve your hand, is not what's called card counting in casino games.
People struggle at memorizing chances, taking shortcuts, computers have exact picture talking into account every single bit.
Memorizing chances isn't very important in no-limit. A rough estimate is all you need because other factors will completely dominate whatever error exists in your estimate. When the implied odds can vary between ~1:1 and 100:1, the second or third digit of your estimate of the chances of making a winning hand (for instance, ~2.5:1 against making a flush) is drowned out.
In car analogy terms, its like worrying about if insurance will cover the broken taillight after your car has been t-boned at an intersection by another car going 60 mph. Yeah, it would be nice if the insurance will replace that taillight... but its more important that they will cover the hospital bills

Amusingly, Bluff magazine has a ranking of the best HUNL players where he's number one. But he's written the list himself :)
He really is among the best heads up no limit players though.
TFS refers to TFA which refers to another TFA, and all of them are pathetically written. Here's a link at CMU discussing the competition. This is the second link in TFS, but it's not clear that all of the other links in the first paragraph are just trash.
In any case, a couple of points and/or musings:
As a final note: may I please encourage submitters and/or our illustrious editors to not fluff up submissions with links to crappy articles that miss most of the important points? Just the source link would have been enough - it's a good article with real information written in actual English.
Enjoy life! This is not a dress rehearsal.
It's my impression that pro players often get amateur players through bet sizing, if your call/fold response doesn't match the equity of your hand they'll pretty easily see that they can milk you for value or push you into folding. Or that the amateurs are bad at getting the maximum value out of their good hands because they give the pros easy call/fold odds. Of course there's a lot more to bet sizing than your own two cards, but you can't bluff properly without having a pretty good clue about what you represent having and making credible bets as if you had those cards. Pros are pretty good at smelling stories that don't make sense where you're betting on the turn/river like you have cards that you'd never play that way preflop/on the flop because they're usually a bluff. Or a very well disguised hand, but they'll sure test if you're capable of that.
