In blackjack tournaments, the goal is to accumulate more chips than your opponents over a set number of hands. Start conservatively, then adjust your strategy based on your chip count. Play more aggressively if you're behind, but avoid risky all-in bets early on. Pay attention to your position and other players’ strategies, and adjust your bets accordingly. Keep calm, manage your chip stack wisely, and be mindful of the time or hand count to maximize your chances of success.
