To manage your bankroll effectively in Blackjack, start by setting a budget that you’re comfortable losing, and divide it into smaller units to help pace your play. It’s important to establish both a win and loss limit for each session, so you know when to stop, whether you're ahead or behind. Betting strategies vary, with flat betting being a safe option for consistent play, while more advanced methods like the Kelly Criterion can help you optimize your bets if you're knowledgeable. Avoid chasing losses by increasing bet sizes when you're losing, and instead, stick to your pre-set plan. If you're playing at a casino, make sure to take advantage of comps and rewards to maximize value. Additionally, manage your time wisely by keeping sessions short and focused to avoid fatigue, and always know when it's time to walk away, whether you're on a winning streak or experiencing a loss.
