I have played BJ for only 100 hours. I haven't discovered any cheating yet. I know that for licensed casino, there's little to worry about.
But I would like to worry about it from the early stage. :-) (For cheatings such as second dealing, it's really difficult to get the hard evidence, so I assume I would just walk away.) But suppose I suspect the deck composition of a single deck, is it OK to politely ask the dealer that I want to check the cards? Will the casino beat me in the nose when I go to the restroom?
What is the risk vs. benefit here?
