The KISS III counting system
A lot of the beginner card counters usually choose to use KISS III counting method especially when they have become familiar with the KISS I and KISS II counting systems. However when you look closer you can easily see that there are very few differences between KISS III and the other methods. The best ever explanation of this method was done in Fred Renzey’s book, Blackjack Bluebook II.
This counting system was introduced to help in improving the efficiency of the counting system by changing the indices of two cards within the system. As a result of this change, a new difficulty level was introduced into the system. In as much as a new difficulty level was introduced, beginners need not worry because it is still a very simple counting method altogether. As a matter of fact, you can learn it so fast and be able to implement what you have learned in live play, hence the name Keep it short and simple (KISS)
This is basically an unbalanced system, which means that once all the cards that are available in the deck have been dealt the ending total does not necessarily have to be 0, and this is one of the main differences between this and all the other counting systems in the game. The reasonable explanation behind this is that when you are using this counting system, it is not mandatory that you start counting at 0. As a matter of fact it is actually possible for you to start counting from a negative range or above the negative figures.
The whole concept of introducing the idea of an unbalanced system is because in this way it is actually possible to clearly give a representation of the state of the game, especially when the deck is most or least favorable for the player. It is also worth noting that as a result of the unbalanced nature of this system, it is best applicable to single and double deck poker games.
