Card Counting Systems
The mathematical effect of taking away the 1st card out of the deck can be seen from the table on the right hand side. As for the coming card, similar values get applied; however it needs to be multiplied with 1.02 for a precise value, the 3rd one with 1.04 and likewise for being precise to the corresponding values which are present in the rest of the deck.
It will nearly be impossible for doing the calculations that are required for giving a good idea of the gain of player without any computer or computing device's assistance, while the game is being played.
Alternatively, a no. of counting card methods is there which employ numbers that stay constant all through the process of counting for providing a rough estimation or idea of the profit. The precision often comes by the cost of more complexity and thusly tough to learn and put it into use. Following are a few other good card counting methods:
High Low:
This particular system was conceived by an author Stanford Wong, who has written a number of books on almost each & every game of casino. In this system, low cards ranging from two to six are valued at plus one while the higher cards like 10s and Aces are valued at minus one.
Red sevens:
This was first started by Arnold Snyder and in a way it is also derived some way or the other from High-low method. It is almost similar to the High-Low system, the only difference being the fact that red sevens do the count as plus one while the black ones do the count as 0. So, in effect, it provides all 7s a value worth plus 0.5, that is sufficiently precise if one considers the effect of 7 on player's gain.
Green Fountain
This system was founded by Koko Ita and this too is a quite similar to the High low method. The only difference being- 7s and 9s aren't considered as neutral. This is surprisingly quite close to the original mathematical weightage of cards, because 7 and 9 aren't really neutral and simultaneously the effect is lesser than one third of one percent.
