Black jack is almost a 50/50 game. And they say if you know how to
count cards then you can come out ahead most of the time. But there is
another way to move the odds in your favor. If you are betting $5
chips at a blackjack table every hand, then if you bring in one fake $5
chip to play with the odds change dramatically! But in a 50/50 game
eventually the odds will move back to where they should and you will
brake even. But in the short run, if you can cheat at even one hand
your odds will improve so you have a much better chance of walking away
with something.

Any math guys have a way to figure out how your odds improve when you
do this?
