When the count is high in blackjack, indicating a favorable situation for the player, you should adapt your strategy by increasing your bets, as the likelihood of drawing high-value cards is greater. It's also wise to be more aggressive in your play, which may involve hitting more frequently, particularly if you're holding a lower total. Additionally, consider doubling down more often, especially when you have strong hands against the dealer's weaker cards. Being mindful of the increased likelihood of dealer busts with a high count can influence your decisions, encouraging you to play more confidently.
