I posted a thread on the internation scene about cheating in the Czec Republic.
I thought that it might was be done by clumping the high (7-10) and low (A-6) together in the suffle somehow. This is only an idea. I'm not sure if it is real.

I have noticed from reading other posts that there is heavy scepticism about clumping having any effect on blackjack. Aparently there is a couple of bogus systems for sale that revolve around this concept.

Anyway, can anybody explain to my why I shouldn't be worried about clumping.

As I see it if somebody deliberatly stacked a shoe so that the low cards are all in big groups then I would always be doubling down against the dealers low card with no chance of getting a high card and the dealer could not possibly break the low card he was showing.

In a high clump there would just be a lot of pushes.

Blackjack could only happen when I got the ace from the end of a low clump and then the ten from the begining of a high one.

So whats the story with clumping ?
