If you're looking for a "rational" baccarat strategy, you're not going to find one. Baccarat, by its very design, is a game of luck, not skill. Sure, you can apply some statistics to know that betting on the Banker gives you the best odds, but even then, it’s about 50/50. All the Fibonacci sequences and Martingale systems don’t change the house edge, which remains in the casino’s favor. I've seen people go broke trying to stick to these systems. My advice? Play baccarat for free online if you want to test out strategies, but don’t expect miracles.
