You can count cards in live dealer blackjack, but there are challenges and risks involved. Casinos, both online and land-based, closely monitor players for card counting and can ban you if they suspect you're doing it. Live dealer games tend to be faster, and decks may be shuffled frequently, making it harder to track cards. Some online casinos use continuous shuffling machines or other software to prevent card counting from being effective. While card counting itself isn’t illegal, casinos have the right to ask you to leave or ban you if they catch you. Overall, while it’s possible, the practice is more difficult in live dealer blackjack due to the game’s pace and casino countermeasures.
