The Martingale betting system in Baccarat involves doubling bets after each loss to recover previous losses and achieve a profit equal to the initial stake. It's a high-risk strategy that can lead to rapid bet escalation during losing streaks, potentially depleting the bettor's bankroll. Despite its appeal in theory, the system doesn't alter the game's odds or guarantee long-term profitability due to the casino's built-in house edge and maximum bet limits. Effective bankroll management and realistic expectations are essential when considering the Martingale strategy in Baccarat.
