You're ready to move from basic strategy to card counting when you have mastered basic strategy and can make the right decisions instinctively, without relying on a chart. You should also be comfortable with understanding the probabilities involved in the game, especially how the remaining deck impacts the odds. Additionally, card counting requires strong focus and the ability to track the count while playing without distractions. If you've practiced counting until it becomes second nature and understand the potential risks, including attracting casino attention, you may be prepared to start incorporating card counting into your play.
