are you barred from the casino? are you barred from all casinos? is there any chance of getting in trouble with the law?
Maybe, maybe, no. Card counting is not against any law.
Your punishment for getting caught highly varies depending on how high of stakes you're playing, where you get caught, and the mood of the pit boss at the time. From mildest to worst ...
(1) Polite countermeasures: penetration will be cut or the speed at which they deal will be sped up or slowed down (depending on what they think annoys you). Generally if you walk away at this point you're free to return on another shift or on another day with zero repercussions.
(2) Annoying countermeasures: pit boss will try to distract you or make remakrs about your play, or otherwise try to hassle you into leaving. At this point your face will be recognized, so it's best to stay away until your face fades from memory.
(3) Backed off: you will be asked not to play blackjack any more (but usually any other game is fine) or for a certain time. You can try returning at a different shift or day, but you'll face worse and worse punishments from this point forward and surveillance likely snapped a photo of you for future reference.
(4) Barred: you will be asked to leave the casino and not to return to the premises. Typically you get read the "trespass act" which is a legal warning not to return. You will get arrested if you return. You're essentially done at that casino and will be on a shorter leash at sister properties.
(5) Backroomed: you will be forcibly taken to the back room and detained until police arrive. The casino legally needs reasonable suspicion that a crime has been committed, but if you're playing high enough stakes or otherwise seriously threatening the casino's bottom line, they might make stuff up to backroom you. At this point, you've got more than "can I play blackjack" to worry about - you might spend a night in jail, guilty or not of what they accuse you of having done. Nevada police will believe the casino 99% of the time.
