Dorkus gave the reasons why you wouldn't be able to buy it.
Here are the reasons they don't exist:
When you are sitting at an online poker table assume you are dealt
The online poker site sends a "Packet" of information to your computer that shows you 2 aces....
The online poker site does NOT send this "packet" to any other player's computer....
The flop is dealt, (viewable to anyone), the turn and river are the same... also viewable to anyone.....
When it comes time for showdown, then and only then is a packet of information sent to your opponents containing YOUR hole cards (In this case, 2 Aces).
That's it. no big mystery. The programs that you want to buy just don't exist. YOU will never see someone else's holecards.
So since Your holecards are only stored on the online poker sites
servers, a VERY determined hacker could theoretically hack in and obtain this information.
Mind you, if they could do this, would they bother with hole cards?
Or go straight to the financial section and take the money without going throught the formality of actually playing?
Now, This does not mean that someone can not see YOUR hole cards.
What you ask?
Well, if you were to download a very naughty trojan file, someone can gain access to your computer, and virtually see what you see, thus seeing YOUR holecards....
How would that get on your computer?
Try downloading one of those "See your opponent's hole cards" type programs, and then you can tell us all about it
