At times betting systems will tempt blackjack players from time to time. They just seem so easy to use and to turn a profit with. But there is a major problem with betting systems and blackjack.
First, a betting system is a method of choosing how to bet each round of blackjack. These systems dictate to players when to raise and lower their bets. These betting systems are progressive in nature and that is what is inherently wrong with them.
You can see the progressive nature of a betting strategy by looking at one of the two most commonly used betting systems: the Martingale method. Players that use the Martingale system will double their bet when they lose a round. So if you lost a $10 wager, you would wager $20 on the next; if you lost that round you would wager $40 on the next. This doubling continues until the player wins a round, and then returns to their original betting amount.
The reason this progressive idea of betting in blackjack is a bad idea can be attributed to the nature of a round of blackjack. Each round in blackjack is independent of the last one. This means that there’s no way to tell when you will lose or win—like how some players think that if you lose, say, seven rounds you’ll win the next.
You have a 43.5% chance of winning a round of blackjack. And if you lost that round, you still have a 43.5% chance of winning the next. And 43.5% on the next. You see how this works?
Because a blackjack player’s chance of winning doesn’t change from one round to the next, it makes a betting system useless. This is because betting systems are based on the idea that a player’s odds of winning will vary from round to round. And a player’s chances of winning in blackjack are set at 43.5%.
Even though a betting strategy is necessary to fill out and complete your blackjack strategy, a betting system is not a worthy substitute for a betting strategy. Betting systems like the Martingale could actually drain your bankroll since they can’t guarantee you a win and a return of the money you lost.
It’s tempting from time to time to use a betting system, especially in a game of online blackjack where card counting can’t be used. But keeping in mind that you could lose more of your bankroll than what you could make using one of those systems.
