The principle of the method is that a card deck with tens and aces is likely to bust the dealer; thus, the deck of cards is in favor to the player. However, on the other hand, a card deck with small numbers is in favor to the dealer. So how does the method of card counting come in?
First, the player should keep track of all the cards which were already played to be able to gauge how rich or how lacking the deck of cards is. The player then assigns a value of point to every card played. He or she needs to do some computation. A card counter does this. The main point is that a plus point is given to a card if it is favorable, and a minus point to a less favorable one. Thus, high cards are assigned minus one (-1) point while low cards are given plus one (+1). Those in cards in between are given zero (0). The card counter then keeps track of all cards played and designates either adding or subtracting points to each and updates the total from time to time. The total process is called ‘running count’.
Another term a player may encounter is the ‘true count’. This is obtained after the card counter divides the running count with the proportion of the card deck size remaining. This then determines the richness or lack in the deck of card.
Also, the counter should check the up card of the dealer. This is to weigh his options and determine if he will bet the maximum or not. The point is that a positive count is of course very good, and a high positive count is always the best. So, cards two to six is given a point value of plus one while cards ten to ace is given a point value of minus one; in between cards are assigned the value of zero. If your count is positive and high, then the deck of cards is in favor of you. With this, the dealer may hit and hit to reach 17 or may get busted. If you can determine that your count is high and the remaining cards are low, bet as high as you can.
Who is the card counter? Of course, it is you, the player. As a card counter, you need to have a very good memory bank and fast reaction so that you can count and compute while playing. This may seem hard but once you get used to it, you will get rewarded for sure.
You may practice with the computer. There are available computer simulators these days. With these simulators, you get corrected if you have made a mistake. These simulators may be programmed with popular systems. These also can keep track of long term wins which you may adopt and apply in your blackjack games. Also, there are many books about counting. Practice your running count with any number you see. For example, you saw a jersey with the number 17. Think quickly: Count is +1 because 1 equals +1 and 7 equals 0.
When playing, limit your money and time. Quit once you reached your limit. Do not waste all your money over a game.
