The concept of "advanced strategy" in Blackjack includes the following elements:

• Exceptions for Single and Double Decks
• Card Counting
• Betting Systems

Let's study these elements more in detail.

Exceptions for Single and Double Decks.
In single deck blackjack every card that is played has a considerable impact on the distribution of the remaining cards. Slightly lower this impact has place also in double deck game. Below are links to exceptions for appropriate cases.
Single deck game, dealer stands on a soft 17.
Single deck game, dealer hits a soft 17.
Double deck game, dealer Stands on soft 17.
"Exception" here means basic strategy deviation and allow to lower house edge by 0.03%. Using this strategy in online single deck blackjack is especially encouraged.
Because all these advanced strategy elements are based on basic blackjack strategy rules, be sure that You know enough good "Blackjack Basic" before play with such exceptions.

Card Counting.
Let us say loud and clear that card counting is hard and is not as rewarding as television and the movies make it out to be. If it were an easy way to make money everyone would be doing it.

If you do not know the basic strategy trying to count cards is highly ill-advised. Experienced card counters still play by the basic strategy the great majority of the time. There can be no short cut around learning the basic strategy, those who attempt card counting without a firm foundation in the basic strategy are making a big mistake.

To be a successful counter you have to be able to count down a deck fast and memorize large tables of numbers as well as make it look like you're just a casual player. Furthermore, with today's rules, a realistic advantage the counter will have is only 0.5% to 1.5%. You will not win money slowly and gradually but your bankroll will go up and down like a roller coaster in the short run. Only in the long run over hundreds of hours of playing can you count on winning. ... Click here to read full article.

Betting Systems.
Simply put, a betting system is a way of using money management to maximize your profits. No matter what technique or method you use to give yourself an edge at the blackjack table, if you don't manage your money properly you will probably walk away a loser. Below are 3 most popular systems.

Martingale System.
This system, which was invented over 200 years ago, instructs the player to double his bet each time he loses, on the assumption that he will eventually win and show a profit from the initial wager.

With a beginning wager of $5.00 you would double your wager with each loss. IE: $5, $10, $20, $40 $80, etc. After a win your wager would drop back to $5.00. All wagers are recovered when you win a hand.

Casinos have table limits to eliminate the effectiveness of this system. After a long losing streak you will eventually hit the table maximum, thus defeating the purpose of this system. Plus, a considerable amount of bankroll is needed to make this system work, and the payoffs simply aren't worth it. If you started with a $5 dollar wager and lost your first four wagers and won your fifth, (without double downs or splitting your cards) you would be a measly 5 dollars ahead. This is simply not worth it, and if you are losing multiple hands in a row it is time to leave the table, not double your wagers. Also, losing double downs or splits can deplete your bankroll in a big hurry.

Progressive Betting System - 2 Level.
This is the simplest betting system to use and still effective. To use this system simply decide on a minimum and maximum bet. Then bet the smaller amount after a loss and the larger amount after a win. For example, say you set your minimum bet at $5 and your maximum at $15. Start with a $5 dollar bet. If you win that hand you bet $15 your next wager. You then continue to bet $15 until you lose. After any loss you return to your minimum bet of $5.
This is a basic, put solid progressive betting system.

Progressive Betting System - 5 Level.
This is another simple, yet effective system, based on a 1,2,3,5 back to 1 progression. Example: For a $5 player, the betting levels would be $5,10,15, and 25. With this system you start with your $5 bet and progress to the next level when you win a hand. If you lose a hand you drop back down to your original $5 wager. If you win four hands in a row you should then drop back down to your original $5 wager, hence the 1,2,3,5 back to 1 progression.

Lets take a look at how this works. This system is rewarding when you experience winning streaks but still doesn't kill you with losing streaks. Lets say you lose your first three hands and then win your next three. Assuming a starting wager of $5 you would be ahead $15 at the end of six hands. If you were betting an equal amount on each had you would be even.

It should be noted that progressive betting systems such as these fail when you experience a win, loss, win, loss, win, loss, type of scenario. In a case like this, you would be better off betting an equal amount on each hand. However, this is the risk you take in your attempt to maximize profits on streaks of 3 wins or more. And in reality it is not as risky as simply using basic strategy and betting an equal amount each hand. The nature of blackjack is such that winning streaks and losing streaks frequently occur, and that is where progressive betting systems maximize your profits.
