I have learned that card counting is legal in blackjack but casinos frown at it. Most casinos have a surveillance camera that watch each table to catch a player who caught counting cards. A player may be thrown out or banned from the casino if caught counting cards because there is a belief that it gives the player an edge. How true is this or this a myth? If for instance card counting is legal in the UK but outlawed by casinos doesn't it makes it illegal?
you’re quite right in noting that card counting in blackjack sits in a unique legal and ethical gray area. Card counting, at its core, is simply a player using their mental faculties to keep track of the cards that have been dealt to gain an advantage. Legally, it’s not considered cheating because it doesn’t involve the use of external devices or collusion with the casino staff; it’s just a skillful way of playing the game.
However, casinos are private establishments and have the right to serve (or refuse service to) whomever they choose, as long as they’re not discriminating on the basis of protected characteristics like race, religion, or gender. Because casinos view card counting as a threat to their bottom line—they’re in the business to make money, after all—they employ various measures to identify and mitigate it. This includes the use of surveillance cameras and even banning players believed to be counting cards.
Your question about legality is insightful. In places like the UK, while the act of card counting itself isn’t illegal, the casino’s right to refuse service to someone they suspect of counting cards means that players engaging in this strategy can indeed be thrown out or banned. This doesn’t make card counting illegal per se, but it does mean that casinos are legally permitted to take actions against card counters. Essentially, while you’re not breaking the law by counting cards, you are violating the casino’s policies, and they have the legal right to ask you to leave or to ban you from playing.
So, while card counting gives players an edge and is not illegal, the reality of being able to practice it in a casino is complicated by the casino’s right to protect its interests.
