Blackjack Systems

The martingale system The martingale system is one of the oldest betting system and it was invented over 200 years ago. This system teaches the gambler to double his wager each time he loses. It is based on the probability of losing infinite times in a row and is usually applied to "even money" bets.
Here's how it works: the gambler makes his standard bet, say 5$ and with every lost he will double his bet. 5$ bet, lose, 10$ bet, lose, 20$ bet, lose, 40$, lose and so on. After a win the gambler drop back his bet to 5$. All bets are reclaimed when you win a hand.
To remove the efficiency of the martingale system in casinos are set table limits, because exists the posibility for the player that after a long losing series to reach the table maximum and so the intention of his system is defeated.
For this system to work, the player needs a significant amount of money and the payoff simply aren't worth it. For example, if a player starts with a bet of 5$ and he lose the first four bets and then win the fifth bet ( without to double down or split his cards) he would win only 5$ more. This is simply not worth it, and if the gambler is losing more hands in a row it is time for him to leave the table and not to double his wager. Also losing double downs or splits can empty his bankroll very fast.
Progressive betting system This betting system is the most simple and effective. What you need to do is to choose on a maximum and minimum bet. You will bet your smaller amount after a loss and the maximum amount after a win. Here's an example: you set your minimum at 5$ and the maximum bet at 15$. First you bet 5$ and if you win that hand than you bet 15$. You will continue betting 15$ until you lose. If you lose, you get back to your minimum bet of 5$. This is a basic system and progressive.
Progressive betting system 2 This is another simple and efficient system, which is based on a 1, 2, 3, 5 back to 1 progression. For example: for a 5$ player, the betting levels would be 5$, 10$, 15$ and 25$. Using this system you will bet for your first hand 5$ and than you will get forward to the next level in case you win a hand. If you lose a hand you get back to your original bet that was 5$. Also if you win four times in a row you should get back down to your original 5$ wager.
This system increases your bankroll if you will have repeatedly wining hands, but doesn't get you at the edge of Bancroft after more losing hands and is still effective while playing online Blackjack. Let's suppose that you start with a 5$ wager, and you play six hands in which the first three hands you lose and the next three hands you win. In that case you would be ahead with 15$ at the end of the six hands and if u were betting an equal amount on each hand you would be even.
There's a situation in which that betting system falls. That situation is when you: win, loss, win, loss, win, loss. In that case betting an equal amount on each hand would be better for you... This is the risk you take when you try to maximize profits on streaks of 3 wins or more. In fact is not so risky but simply you use basic strategy and you bet an equal amount for each hand. The nature of blackjack is such that winning streaks and losing streaks frequently exist, and that is where progressive betting systems increase your profits.
