Lots of hub bub in the poker community about some apparent cheating that has been going on at AbsolutePoker.com. Bobby has a nice comic about the cheating at PlusEV.net, and probably the best place to get info and updates is Absolute Poker Cheats blog that was setup just for the occasion.
Traders will appreciate this chart showing how much of an outlier one suspected cheater is. That red dot in the upper right corner represents the win-rate of the suspected cheater. The trading analogy would be a trader who trades 90% of the stocks on the market and correctly predicts the stocks movement 90% of the time. With stats like these, you could make an insane amount of money. And that’s exactly what these guys have done, reportedly making hundreds of thousands of dollars in a short time.

For the poker illiterate, VPIP stands for “variably put money into pot”, which is a statistic that tracks what percentage of hands you play. Good players are in the 15-30% range. The cheaters are in the 70-90%.
BB/100 stands for “big blinds per 100 hands”, which measures how profitable you are. So if you were playing $100/$200 poker with a 1BB win-rate, you would win on average $200 every 100 hands. Winning players can make about 1-3BB/100 at the medium and high limits. In the short term (across a small number of hands), lucky players can make about 100BB/100 hands. The cheater graphed makes 500BB/100.
The graph is pretty damning, but probably most damning of all (at least to a poker player with a bit of knowledge) is to go over some of the actual hand histories that leaked for this player. You can read some play-by-play analysis with some guesses as to the cheaters thinking here or see a video replay of the hands here (requires a free registration). The short of it is that the villain is playing uncannily like he/she can see the other players cards.
Is there cheating like this going on in the stock market?
Obviously, Martha Stewart-style insider trading goes on, but what I’m thinking about here is the kinds of cheating available to unethical brokers. Unlike the online poker rooms, many of the big brokers have their own traders “playing” in the same market as their clients. This creates the same kind of conflicts-of-interest that the poker sites try to avoid.
