Entire forums are devoted to bad beats. Beats like these cause some players to proclaim that online poker is "rigged." I don't necessarily agree with that contention; that in some manner, some hands are programmed or designed or rigged to clash with improbable upset outcomes. Of course, online poker generates a tremendous volume of dealt hands which doubtless is bound to generate equally high volumes of bad beats. As the myriad of uncanny bad beat stories seem to invite, however, this is a spectacle that might warrant a moment's consideration.

Zaphod leaped out of his seat.
"Then what's happened to the missiles?" he said.
A new and astounding image appeared in the mirrors.
"They would appear," said Ford doubtfully, "to have turned into a bowl of petunias and a very surprised-looking whale..."
"At an Improbability factor," cut in Eddie, who hadn't changed a bit, "of eight million, seven hundred and sixty-seven thousand, one hundred and twenty-eight to one against."

Its worth noting for any new or inexperienced players, that there is a difference between a bad beat and just being beat. An A-K vs. pair coin flip is generally a regular beat. A bad beat is more of something powered by the starship Heart of Gold's Infinite Improbability Drive from Hitchhiker's Guide to the Galaxy. When only one card in the deck on the river can make a hand actually arrives, or only limited or specific runner-runner turn and river cards can turn the tide, comes to pass -- uncannily and seemingly against all probability -- it likely qualifies as a bad beat.

The Hitchhiker's Guide to the Galaxy says that if you hold a lungful of air you can survive in the total vacuum of space for about thirty seconds. However, it does go on to say that what with space being the mind-boggling size it is the chances of getting picked up by another ship within those thirty seconds are two to the power of two hundred and seventy-six thousand, seven hundred and nine to one against.
By a totally staggering coincidence, that is also the telephone number of an Islington flat where Arthur once went to a very good party and met a very nice girl whom he totally failed to get off with...

A hole-in-one or amazing shot in golf may be improbable and rare, but not impossible. Even in live poker, the rare does occur, like the quad Aces running into a Royal Flush at the 2008 WSOP or the crazy hand in this match in Europe where in one hand was dealt, Qs, As, 5s, 7s and Ks. My own live poker experience is less than many others' I'm sure, but I have seen some (small) number of uncanny live hands. I have to acknowledge that the seeming volume of unnatural beats online may be, in some measure, merely a product of perception combined with, well, high-volume.

The equanimity of your average tosser of coins depends upon a law, or rather a tendency, or let us say a probability, or at any rate a mathematically calculable chance, which ensures that he will not upset himself by losing too much nor upset his opponent by winning too often. This made for a kind of harmony and a kind of confidence. It related the fortuitous and the ordained into a reassuring union which we recognized as nature. The sun came up about as often as it went down, in the long run, and a coin showed heads about as often as it showed tails. Then a messenger arrived. We had been sent for. Nothing else happened. Ninety-two coins spun consecutively have come down heads ninety-two consecutive times..."

On a more technical note, I think some of the uncanny-ishness of at least some of the bad beats can be explained by the limitations of programmers and programming structures at generating true randomness. I have some limited programming knowledge, know some programmers, and have a rudimentary understanding of the difficulties involved in random number generation. Computers are given more to logic and order and sequencing rather than chaos and randomness. Of course, I'm sure programmers smarter than myself have developed algorithms to the best of their ability to create the best randomization they can. To that extent, I don't think the game is rigged; just slightly flawed perhaps.

Spock: I have never computed them, captain.

I am looking forward to the release of Real Deal Poker to see if their high hand volumes show similar levels of infinite improbability or not. (Actually, that might make a good name for a poker site: InfiniteImprobabiltyPoker.com.) Or if the perceived volume of improbability we see is, in fact, a logical degree of normality. It should prove interesting either way. It is an unfortunate truism that it seems Americans will not be able to play for cash on Real Deal when it launches, until their owners say they allowed to. Sigh.

In the meantime, fire up the Poker Stove for roasting the nuts, strap yourself into your chair, start up your favorite poker site, engage your Infinite Improbability Drive and hang on... its liable to be an inconceivably wild, tilt-worthy, rollercoaster ride. And try to enjoy yourself along the way.
