I think your last question has been answered
Well, there are other ways of cheating that I've seen on tv that doesn't include cards. I've seen a person have a shell like cover to put over chips to make it look like he has more than what he actually has.
Let me explain. . . . . .
I remember there being red chips and blue chips. Blue chips were more $. So he had a shell of what looked like blue chips that he puts over the red stack, making it look like he had more money, so when he went all in, the other players had to put up more chips.
There was also something else I remembered from the show on how to rob chips. People standing by a person at a table who was doing good, would say something like, "may I tap your chip pile for good luck", as they had a mug in their hand. The player at the table would say sure. So the person taps the top of the chip stack with her mug and casually walks away.
Little did the guy know that she just robbed 1 of his chips off the stack because at the bottom of her mug was double sided tape.
So there are some other ways to cheat that doesn't have to do with cards, just chips.
