I think buying a "Baccarat book" or guide is unlikely to improve your chances of winning. These resources typically promise unrealistic results or rely on unproven strategies. Baccarat is a game of chance, and no book or guide can overcome the built-in house edge and I also feel that instead of relying on unproven strategies, it's essential to understand the game's rules, odds, and inherent randomness. Managing your expectations and bankroll effectively will serve you better than any guide. Save your money and approach Baccarat with a realistic perspective.
