Physical Gambling operators consider card counting a big threat to their business so they will try everything to eliminate that threat every players that comes along that is having a good success even if they are lucky that night is analyzed and if they have a continuous round of success chances are they will be ban.
Well, technically I agree with you. But for me, there is nothing wrong using with this and I am not also using this method of card counting, -- I will not risk my money and betting someone that has an advantage. Stick with your odds and play fair to them, no need to use any other card counting to taking advantage against your opponent. However, a casino has a right to choose if you will stay in or kick you out if you are taking advantage of someone else.
