The most popular approach to baccarat concerning betting systems is a martingale system. Martingale is the system which requires doubling a bet after a loss (or in some types after a win), for example, you have lost a $5 bet so the next time you should bet $10. If you lose again the third bet must be $20. If you win the third bet you will get $20 and return your bet, so a total will be $40. As you see you recoup your losses (the first $5 bet and the next$10 bet). You also make a $5 profit. But this system is very insidious and may result in big losses indeed!
