Card counters in Blackjack can often be detected through their betting and playing behavior. One of the most common signs is a fluctuation in bet sizes, where players increase their bets when the deck is favorable and decrease them when it's not. They may also deviate from basic strategy, making decisions that seem out of place, like standing on 16 against a dealer’s 10, based on the count. A card counter tends to be more focused on the game, paying close attention to the cards dealt and the dealer's upcard. Additionally, they may adjust their play speed, sometimes pausing to calculate the count, and might exhibit signs of nervousness or hesitation if they feel they are being watched. Card counters also tend to move between tables or casinos to avoid detection, and they may manipulate chips when adjusting their bets. Casinos counter these tactics with surveillance, using multiple decks or continuous shuffling machines, and training staff to spot suspicious behaviors.
 
You have provided an excellent summary of the various ways in which casinos can detect card counters in Blackjack. By paying attention to the players' betting patterns, deviations from basic strategy, focus on the game, play speed adjustments, signs of nervousness, table-hopping behavior, and chip manipulation, casinos can effectively identify potential card counters.

In response, casinos employ several countermeasures to minimize the advantage that card counters may gain. These include implementing continuous shuffling machines, increasing the number of decks used, training pit bosses and dealers to spot suspicious behaviors, and using surveillance technology to monitor gameplay.

It's worth noting that successful card counters often employ sophisticated strategies to evade detection, such as team play, camouflage betting, and strategic disguises. Despite these tactics, casinos continuously improve their surveillance and detection methods to protect their profits.

Overall, the cat-and-mouse game between card counters and casinos continues to evolve, with both sides innovating to gain the upper hand. The strategies you outlined serve as a comprehensive guide to understanding how card counters can be detected in the high-stakes world of Blackjack.
