Tracking Online Cheaters in Poker

prostoalex writes "MSNBC has a special report on discovering online cheats at AbsolutePoker.com. A Costa Rican company belonging to a Canadian tribe at first denied all the accusations of any cheating going on, but after Serge Ravitch made a scrupulous analysis of the games' events, the reputation of AbsolutePoker.com was at stake. A detailed log file provided investigators with necessary details: an employee and partial owner of the site was one of the players involved, and having direct access to other players' cards allowed him to improve his game substantially."

Well, duh! That's why it is called "gambling"

[registrations_suck]

Is anyone surprised? Off-shore gambling sites have no real oversight whatsoever as far as I know (unless Vegas, et.al.). Of COURSE people are going to get ripped off. As much as gambling on the cards, people are gambling on the site itself - and in this case - the guilty parties were gambling that no one would notice. Gambling all the way around. This is just one of many reasons why the U.S. is just out and out foolish to continue banning on-line gaming, when instead, it could bring it to shore, charge gazillions for licenses, tax the proceeds (for both the house and the gamers), and as an added bonus, enact various certification and oversight requirements that would provide some measure of protection while allowing government to do what it does best - grow even larger.

First, AP's wasn't offshore. It was run out of Kahnawake. Which is in Canada. (Okay, Quebec, so it's SORTA in Canada).

Second, there is oversight. There's the Kahnawake Gaming Commission. But, admittedly, they blow at customer relations. But with their backs against the server-room, they're actually doing something about this one. They're commissioning an independent investigation to see what's going on. Again-- because it would be bad PR otherwise.

And that's where the real oversight comes in. The players are what keep the online casinos "honest". Players like those who discovered the AP cheats. People who know how the games should be running, and know when things aren't being run correctly. Then there's player run oversight groups like Casinomeister. And there's also people who have put up tons of statistical information about online games, like The Wizard of Odds

A casino with a bad reputation gets spotted, gets talked about, and goes out of business. The online gambling world's potential playerbase is relatively small, and there's a LOT of businesses who want a piece of their action. Screw up once, and every single player has five hundred other places they can go to.

collusion

[bcrowell]

This particular story has to do with a security hole in the computer software, but in general, my understanding of the logic of the game is that online poker is potentially the only way to get a guaranteed honest game with strangers. In a meatspace game with strangers, the problem that basically can't be solved is collusion. Player A and player B both walk into the casino, and pretend they don't know each other. In reality, they've arranged certain secret signals in advance, to be used in hands where the pot gets big. One signal might mean "I'm bluffing," and another might mean "I'm not bluffing." Over time, this gives them a huge systematic advantage. An online poker system, on the other hand, can at least potentially be set up so that A and B can't get themselves into the same game together -- you just have to have a large enough pool of users, and assign them randomly to games. The other reason I'd never play in a casino game is that the house's take is big enough that you're practically guaranteed to lose money in the long run, unless you somehow manage to get into games where your skills are extremely high in comparison to your competitors'.

Re:collusion

[Astarica]

The problem is that as you move higher and higher stakes there are increasingly few players so it is easier and easier to get you and your friend on the same table. Assuming you and your friend are at least no worse than the average player of that level, it has to be the case that you'd win if you collude, so the only thing that holds you back is your capital. I believe the statistics say that the knowledge of 2 extra cards is basically insurmountable over the long run in poker. And in online there's nothing stopping me from calling my friend and say I got these cards, what do you got? And there's no way anyone can catch that. If you try to cheat in a real casino, people would eventually notice. But that isn't possible for online.

Re:collusion

[stirfry714]

Umm, poker rooms (whether live or online) have no "advantage" statistically. They aren't "loose" or "tight" like you'd think of in slots.

The house takes a fixed amount of every pot, called the "rake". Sure, some casinos take more than others, but it's not because the software is fixed one way or the other - it's because they've said upfront that they are going to take X% out of every pot.

That's a big reason a lot of us love poker - you aren't playing against the house. *Any* game you play against the house, you will be losing money in the long run - a casino isn't going to spread a game that it will statistically lose money on. (Card counters in blackjack being a rare exception, where they can eak out an overall 1% return on investment if they get away with it).

Poker you play against other players. Sure, there's luck and variance involved, but in the long-term if you are more skillful at the game than other players enough to beat the rake, you will make money, guaranteed. That's why there are professional poker players - they are good enough to make a consistent living at the game. No such thing as professional roulette or slots players - as much as some people might try! :)

Isn't calling out on the same phone line your modem is using a bit difficult?

If you try to cheat in a real casino, people would eventually notice.

I'm not sure how. For example, if you and your friend sit at the same table in the casino, and you've worked up a system where he plays very tight (comes in with nothing less than a 10-10 or A-K), he can explain his play as following one of the books (Helmuth, I think). Before he folds he plays with his chips, just like everyone else does, and uses the chips to signal to you what he has. Maybe makes two stacks of the appropriate height. Since the casino does not know what he folded, they cannot coorelate his actions with specific values of cards.

If he doesn't fold, he uses different chips for card protectors depending on what he has.

Of course, you cannot sit and stare at him until he plays with his chips, or ask him to do it again, and he cannot be obvious about counting out how many chips or you might get caught as being just plain suspicious. Otherwise, you'd blend into the normal pattern of play.

Re:collusion

[Anonymous Coward]

To gain an advantage, eventually you have to make a move that would otherwise not make sense. Make enough of these moves, and people begin to notice.

Online poker sites keep records of every hand that is played for money. They can go back and check hand histories to look for collusion. Most the time the people doing it are quite amateur, and their play reveals what they are doing. The hand histories of online poker sites theoretically make it much easier to catch collusion online than in B&M poker.

Re:collusion

[jaffray]

It's much easier to catch colluding cheats online than in a live game.

Online poker sites have vast quantities of forensic evidence - complete hand histories, including the actions and hole cards of all players involved, for every hand ever played. Easy to datamine for suspicious patterns, and sites like PokerStars have people doing that full time. Surveillance video of live games isn't as complete, isn't stored for as long, doesn't include hole card data, and is vastly more difficult to review.

I routinely play for thousands of dollars both live and online. I'm not too concerned about being cheated in either, but I'm more concerned about the live games than the online ones on trusted sites.

cheating has to happen

[Astarica]

The stakes of online gambling is simply too high, and it's far easy to cheat. If I simply call a friend who lives in another location and exchange information, how will you catch that? Many of the high stakes table only has 1 table so it's not hard to get on the same table. If you assume the cheaters are actually good players then it is also not necessary that you always play on the same table. Poker is a game of information, and knowing even 2 more cards compared to others give you a huge advantage.

Because each of you two individually suck at poker, but observably improve when you're at the same table?

Re:Silly gamblers

[Dun Malg]

I think people who play online poker are crazy. The whole point of the game is making judgements about the cards people are holding from their behaviour. A large part of their behavior is how they bet and how long they take to do it. That's still visible. Believe it or not, most decent poker players have a pretty good "poker face". It's not like you gain much insight at live poker looking for twitching eyelids and nervous ball-scratching.

Re:Silly gamblers

[stirfry714]

"Making reads on people" is only a small part of the game. Sure it's an important part to make certain borderline decisions, but there are far more important considerations - hand selection, betting strategies, pot odds, etc...

Yes, playing online takes away non-verbal tells. But it also gives you ammo in the form of hand histories, betting patterns, etc. You can gain far more information about an opponent if you know how he's played in the past than you ever could off a potentially deceptive tell.

Also, if you're wondering why some people play online, it's because there's far more diversity of games - typical live poker rooms these days are just $1/$2 NL HoldEm fests, with very few other tables. Plus many players enjoy the faster rate of the game, and some even multitable, having numerous tables open at once. You can play *far* more hands per hour online than in a live game.

With that said, I do enjoy live poker more, and I would play it more often - if only it was legal and regulated in my state. Too bad I have to drive three hours to find the closest poker room.

Re:Silly gamblers

[AuMatar]

In both online and offline poker, the biggest clues to your opponents are *not* facial or body language tells. Those are too easy to fake. The real clues are betting patterns and logic. Those are not only obvious online, they're easier to spot. Bots are actually fairly easy to beat, they can't use second order logic (playing your opponents tendencies, not just your cards)

Tip of the Iceberg

[posdnous]

This is only the tip of the iceberg.

from the article, it mentions that the cheater was so blatant at cheating because they had a personal vendetta to prove to the company about it's flawed security. Basically the cheater told the company that it's systems were vulnerable and they wouldn't listen, so he set out to prove a point to them. Only after basically being so blatant at cheating that people thought he was god, and complained umpteen times to Absolute Poker did they do anything about it.

Basically what this proves is that, there is no way a real cheater will be caught. A real cheater is not going to do things to draw attention to themselves, if they can gain a 100% edge by cheating, they won't press it to it's maximum, they'll only press it slightly so that they only have a 55% edge, time and compounding will make them rich beyond their wildest dreams, and NO ONE will be the wiser.

A very good summary

The Absolute Poker Scandal
October 16th, 2007 5 Comments

Is AbsolutePoker.com rigged?

Either way, the company is in big trouble. What follows in this post is huge news in the world of online poker and online casinos.

Our story begins in 2003. Absolute Poker's software is in development and many test accounts are created to make sure the program is working correctly. One of these test accounts, known as account #363, can see the hole cards at any table. This test account can not be used to play in real money games, it is only used for development purposes to see that pots are distributed correctly. The id number of this account being #363 is important because this tells us that this was one of the first accounts ever opened in AbsolutePoker, making it very likely the person in control of this account is someone with intimate ties with the company (owner, founder, employee, programmer, shareholder, etc.)

Follow with me to the opening of Absolute Poker (AP). Four people in different parts of the United States open up accounts at Absolute Poker. These four individuals do not know each other. The names in question are Graycat, Steamroller, DoubleDrag, and Potripper. They play in Absolute Poker for a bit, but they don't do well and their accounts are not logged into for many months. These are actual and real players, they are not fake players, they do not know each other, and they are not cheaters.

Key moment in the development of Absolute Poker: a major software upgrade is in process in 2007. The company hires programmers from many areas, including Costa Rica. Our villain in this scandal comes across the test account #363 with hole card access. Visions of big money flash in front of his eyes as he envisions hacking his way to big casino cash. He hatches a plan.

He finds inactive accounts at Absolute Poker and changes the password to these accounts at the server level. He opens test account 363 at a separate computer which allows him to see all the hole cards at the table. He then gets family and friends to cash out his winnings to. The way he does this is after he gets a big amount of cash at the poker tables, he plays against his relatives and buddies and loses all his cash to them. DoubleDrag loses to Reymnaldo, Graycat loses to SupercardM55, and Steamroller and Potripper lose to other various friend and family controlled accounts.

September comes, and as the money piles up, so does the ego and greed. Other poker players make comments in chat that they suspect there is cheating and collusion involved. He logs in as DoubleDrag and then loses every hand intentionally in No-Limit in an attempt to cover up his scam as he senses other players may be on to him.

September 12th. A well-known online poker tournament player named Marco Johnson, who plays under the screen name CrazyMarco plays in a $1000 buy-in tournament at AbsolutePoker.com. Cheat account Potripper is also playing in this tournament. CrazyMarco loses a head-to-head battle with Potripper when Potripper and asks for the hand history of the final table.

September 17th. The four Absolute Poker accounts (Graycat, Steamroller, DoubleDrag, and Potripper) are suspended and frozen.

September 21st. AbsolutePoker sends CrazyMarco a huge Microsoft Excel spreadsheet file (10MB and a full 65,536 rows, which is limit in Excel for most current versions). The spreadsheet is too complicated and scrambled to look into, so he saves it and decides to analyze it later.

October 12th. An AbsolutePoker.com official statement is released with their official comments on the cheating rumors, gossip, controversy, and overall poker community outrage. The company has been made aware of the poker blogs, chatrooms, and online casino discussion forums that are talking about this situation and they state that they take these allegations "extremely seriously". They have "determined with reas

Re:Silly gamblers

[RCSInfo]

Here is my reservation with online poker - what if instead of a table of bots, you were playing a single bot holding 4 hands? The bot still doesn't have perfect information, but can now factor in all of the cards from all hands that it sees. For that matter, what keeps a human player from starting a 2nd account and playing two hands at the same table?

Re:Silly gamblers

[bluekanoodle]

In a real casino, you don't play against the house in poker, you play against the other player. The casino takes a cut of the rake for providing the atmosphere, the table, and the dealer. As in onlone and "analog" play, it is in the casino's best interest to ensure fair play at a poker table. If players don't feel the play is fair, they'll go somewhere else, and if they go somewhere else, the other players will follow the action. As far as table games go, where you are playing against the house, why is it 'cheating" when the casino provides a game that statistically you are bound to lose, and yet you still play? Disclaimer, I work in the Casino indistry, but I also know better to play the games, because the odds aren't in my favor.

Re:Silly gamblers

[John Betonschaar]

It's relatively trivial to have a bot that can try different techniques depending on who it's playing against, and learn what works and doesn't. No it isn't. You think it's easy, but the fact that no-one has ever before created a poker-playing bot that does better than even mediocre human players disproves this.

Creating a bot that defeats weak players is trivial, ie: players that have no sense of the odds they will hit something and make decisions that you can prove to be wrong based on the mathematics of the cards. A computer could calculate perfect odds and only play on them. However, such a bot would lose agains even a mediocre player that uses deception in his hands, plays bluffs, and watches the computers betting patterns. It's not hard to spot mathematical play.

Creating a bot that plays like a poker pro would require a combination of programmed intelligence, mathematics, player statistics, and second-order logic. There is no 'algorithm' that plays good poker yet, that I know of. It's not trivial.

Re:Silly gamblers

[Turkot]

This AbsolutePoker.com approached my company about 6 months ago. They were inquiring if I could supply security monitoring for their online gambling. Their focus was strictly the client, client blocking and not their servers. After examining their state of affairs and our specialties, I declined. Obviously this was the correct choice. I assume by this report they wanted to ensure they were the only ones that could cheat. With attitudes like that, why am I not surprised to find them getting their 15 minutes of fame on slash dot. :)
