When dealing with a losing streak in Blackjack, it's important to stay calm and disciplined. Stick to basic strategy and avoid making emotional decisions, as they can lead to greater losses. Set a budget before you start playing and adhere to it, knowing when to stop if you reach your limit. Chasing losses by increasing your bets is a risky move that can spiral out of control, so resist that urge. Taking regular breaks helps you reset emotionally, preventing frustration from clouding your judgment. Remember that losing streaks are part of the game due to the inherent variance, and focus on the long-term rather than short-term outcomes. Finally, if you're feeling frustrated or the losses are impacting your play, don't hesitate to walk away and come back when you're in a better mindset.
