what if there's a way to count cards that is undetectable?
have you heard of this memorization technique called memory palace?
if a person can remember a full deck of cards in less than a minute they can probably count cards and memorize it without being detected...
Yeah, I've heard about the memory palace, it's basically something like remembering things through association, so you remember one thing, that then triggers the memory of another thing, etc, until you remember the thing you wanted to get in the first place, or something like that. Seems to be very effective it seems.
I reckon casinos will just notice someone is winning more than the average and they will have a look on them. I think they can kick you out for no reason, although I might be wrong there.
