Although the system described in the previous chapter, we consider it the easiest, this too, we will tell you is no less than the following. Although the problem with these easy systems is their effectiveness, it is known when it is too easy; then, it is less effective. This system considers the figures (which are worth 10) among the cards in the deck for counting and an indicator of the greater risk we could take on the bet.
In a single deck of cards, consisting of 52 cards, the ratio of the figures to the total of the cards is 3.25. In fact, in a deck, 16 cards are worth 10 (the 10 and the figures) out of a total of 52 cards, and therefore the ratio is 3.25 (52/16). In the count that takes place, you only have to consider the cards that are worth 10 that come out and based on that figure if there are more likely to come out in these hands or not. Of course, you have to keep track of how many decks there are before the shuffle and, based on that, to understand the cards that are advancing and, therefore, the relationship in which you are at the moment.
To do this counting, you have to be good at the accounts; otherwise, it will be difficult to keep up. The certainty is that the initial starting ratio is always 3.25 (regardless of the number of decks), and gradually the cards come out; you have to mentally update this ratio.
The rule to follow is that if the ratio exceeds 3.25, then our odds decrease, if the ratio decreases, our odds will increase. All this takes into consideration that the more cards that are worth 10 there are than the total and the more there are probabilities of making 21 or in any case a number that is approaching such as 20. This is simple to understand because if the ratio increases, it means that they decrease 10 value cards compared to the total and vice versa. The absurd case to make you understand what is written is that on 52 cards 20 “normal” cards come out, so it means that on 32 cards as many as 16 have value 10 so the ratio is 32/16 = 2 On the contrary if 10 cards of value 10 come out, it means that out of 42 cards left only 6 are worth 10, so the ratio is 42/10 = 4.2
We happened to exploit this strategy with a trick in the various counting; in fact, we are not calculating the ratio every time because we are not capable (some would succeed but not us), but we go to the nose. The trick is always to consider the ratio of 1 out of 3. If a figure on 3 cards comes out, then the ratio remains around 3.25, and therefore we are in a situation of uncertainty, while if the cards that are worth 10 come out more than 1 in 3, then the ratio will decrease and the odds will increase.
Take this system as personal culture, and if you apply, it always does it on the nose as we did. Although this is an easy system, always keep in mind that it is not a precise or scientific method: in these situations, the blindfolded goddess is always the master!
In our opinion, it is important to master the system of figures often as it is a basis for understanding card counting in general.
