Hi RR Spore,
Unfortunately casino's have additional rules that stop any win theory dead in it tracks. Though at black-jack they cannot, however I am sure that they will oust you as soon as they discover that you use a winning system.
BTW: I am pretty sure that such a winning system would mean "hard work" instead of an "enjoyable evening" :-)
It's a bit like funds really. The funds for the small boy's (us) have so many rules to live by that they have a hard time making any money at all. (Why do you think funds compare their results to an index, instead of using absolute numbers?.) In stead, if you own the house (in casino speak), then you have access to funds (hedge funds) that are allowed to do all sorts of things. (In a lot of these funds, the fund manager is only paid IF the fund makes money, a nice incentive eh?)
Best,
Rien.
