Techniques of Blackjack Card Counting. There are a number of different counting systems. We reviewed most of them and will add reviews of any new discovered ones. Check the review of particular systems to see how does the system work along with history, recommendations and rating. One of the simplest counting systems is called the High-Low. Card counting is an advantage-play method that helps you determine when the blackjack odds are in your favor. It involves tracking cards as they come out of the shoe and assigning them point values. The running count helps you figure out when the shoe is rich in aces and 10-value cards. The Red 7 Card Counting System offers blackjack players something that is rarely found among card counting methods today. It combines simplicity with professional-level efficiency. Anyone familiar with basic blackjack strategy and the general rules of card counting can, with a minimum of practice, master the Red 7 card counting method. All blackjack card counting systems have the same basic idea: They track the amount of high and low cards already dealt. The purpose of card counting systems is to. Card Counting Systems In order to be completely accurate, a system must be based on the effect that removing a card of any value will have on the player's advantage in the remaining deck. Mathematically, the effect of removing the first card from a deck is shown in the table below.
How Counting Systems Work
Simple Card Counting System
Let me give you just a bit of the thinking behind counting systems so you'll understand how, and why, they work.
All the systems, in one way or another, recognize the importance of the different cards to the player. For example, the most important card to a player is the Ace, because it's part of a ‘blackjack‘ or ‘natural‘, as we prefer to call it.
The bonus that a natural pays is of paramount importance; it's worth about 2.3% to the player.

In other words, if a game pays only even-money for a natural, the casino gains an additional edge of 2.3% on the player, over and above the edge they may already have because of the other rules (dealer hits A-6, six decks, etc.)
Therefore, the removal of an Ace from a deck or decks of cards has a measurable impact on a player's edge.
As an extreme example, if all 4 Aces are removed from a single-deck game, the casino will have a huge edge which is virtually impossible to overcome. So, the 'effect of removal' for Aces is significant and can be quantified.
The same is true for the 5; it's the most important card for the dealer, since it makes all those 12-16 hands which the dealer MUST hit into 17-21.

Remove all the 5s from a single-deck game and the player has a nice 2+% edge over the casino. So, the 'effect of removal' for 5s is also significant and can be measured.
Thus, the first thing a counting system does is give us a way to calculate our advantage or disadvantage over the casino as cards are played or ‘removed'.
Another role of a good counting system is to give us some idea on how to play the hand. Or, more correctly, when to deviate from the proper playing strategy.
To use the example above, if we were in a single-deck game and all the 5s had been played, would you hit a 16 against a dealer's 10?
Well, you might, but the play of that hand has been affected by the removal of the 5s. So, obviously, we have an 'effect of removal' when it comes to playing the hand, as well as figuring our advantage. But this is, as you can imagine, less precise because the values are constantly changing.
The value of a 5 when we have a 16 to hit is very high, but the value of the 5 when we have a 9 to double is very low. All we can do is basically average the impact of a 5 when playing a hand and hope for the best.
You can see where this leads: if a counting system is good for betting purposes, it's not as good for playing purpose and vice-versa.
Before we leave the theory part, we need to address one more area and that's the insurance bet.This is really simple and all our analysis is based upon one question: Is the dealer's hole card a 10? The odds on that are easily figured and, if we keep track of the proportion of 10s to other cards, we can make ‘perfect' insurance decisions. (I say ‘perfect‘, because we won't be right all the time, but in the long run we'll show a profit from the bet if we use a 'ten-count').
The ability to make accurate insurance bets is very important to a counter, in fact, it's the single-most important basic strategy variation, since it accounts for a full third of all the gains we'll make by varying basic strategy. (Depending upon the basic game, our bet spread and other variables, we can expect to add about 0.2 to 0.4% to our average edge by varying from basic strategy according to the count.)

High Low Card Counting
How well a counting system ‘predicts' the 10 in the hole is an important consideration. A system which is very accurate for the insurance bet is, surprisingly, pretty good at making playing decisions, but it's downright poor at indicating our edge over the casino.
The Three Ratings
All counting systems or methods can be rated in three ways for how they treat the factors mentioned above.
The first rating is a system's 'betting efficiency', which indicates how accurately the count measures your edge over the casino. For example, if the rules of a casino indicates that they have a 0.5% edge over the player who uses proper Basic Strategy, a counting method with 100% betting efficiency would precisely measure the edge (or lack thereof) for the player, IF the player was keeping the count accurately and figuring the true count correctly. How to win at casino slot machines. Of course, some sort of money management program would still be necessary, because even though a player may have an edge, it doesn't necessarily follow that s/he is going to win the hand.
The second rating is the 'playing efficiency' which measures how well the system guides us in making basic strategy variations except the insurance decision, which is treated separately; and that's the third rating; 'insurance efficiency'. Dreams of egypt slot machine. All of these ratings are shown as averages, since there are times when a system can be very accurate and, at other times, it can be very inaccurate.
The Hi/Lo system, for example, is very accurate when it's indicating you should double 11 versus an Ace, (82%), but quite inaccurate when telling us to stand with 16 versus 9 (53%).
The Best of the Best
The best count for the insurance bet is 100% accurate, as is the best count for betting. The best count for playing purposes is about 70% accurate, but unfortunately, no count currently exists which can offer all this in one package. So, you have to decide which will work best for you.
If you play a lot of single-deck with a 1-4 spread, then a system with a good playing efficiency will probably be best, if you have the opportunity to spread from 1-12 betting ‘units', then you'll want something with a strong betting efficiency and, if you often play with a friend or spouse at the same table, you should have him or her learn the best insurance count and work out a signaling system to share information.
My Personal Preference
I teach the Hi/Lo system of counting because it's easy to learn, easy to use and relatively effective at most games, particularly multi-deck games where a large bet spread can be attained.
But I recognize that Hi/Lo has its limitations and the games available to you may be better exploited by a different system.
In this series, I'll examine a lot of the different counting systems so that you can make up your own mind regarding which is the best to use.
I find, by using the training methods I've learned, that it's fairly easy to learn a new counting method; in fact, I use a different system when I play single-deck games and I have few problems in keeping my count straight after just an hour or two of ‘refresher' practice.
I will say, however, that on any particular trip, I stick to one or the other.
I never try to play some single-deck, then a bit of multi-deck and then move back to single-deck, unless I use the same ‘system'. But, to keep it simple, I just play one or the other, so when in the Reno/Tahoe area, I stick to single-deck; the same is true in Mississippi, whereas I play all multi-deck in Las Vegas.

The Series
What I'll do here, over time, is try to examine the various counting systems out there in a rational order. Not only will I give you their 3 ratings, but will discuss their pros and cons as well as their strengths and weaknesses.
Numbers alone don't tell the story; if you play for many hours at a stretch, a difficult system isn't going to be very effective if you're making a lot of mistakes, for example. We generally classify counting systems on ‘levels'. The Hi/Lo is a ‘one-level' system, because all the point values are +1, 0 or -1. A ‘two-level' system uses +2, +1, 0 -1, -2 and a three-level system counts one or more cards as 3, etc. You get the idea.
I'll also address unbalanced systems which do not require a conversion to true count and we'll take a look at some ‘theoretical' systems as well. (How about one where the Ace is +51 and the 10 is -180; not practical for a human, perhaps, but not too difficult for a computer).
Just so you know, the Hi/Lo has a betting efficiency of 97%, a playing efficiency of 51% and an insurance efficiency of about 80%.
