Basic Hi-Lo Blackjack Card Counting System One of the easiest and most popular blackjack card counting strategies is the Hi-Lo Count. The reason this strategy is so popular is that it is simple to learn and easy to implement. Just because this technique is defined as basic doesn’t mean it is not effective. For an expanded, updated version of the Hi-Lo Lite Card Counting System, as well as the Zen count and information on how professional gamblers win at blackjack without card counting, see Blackbelt in Blackjack by Arnold Snyder. For the original Hi-Lo count, see Stanford Wong's Professional Blackjack.
According to Norm Wattenberger at QFIT, the strategy was
originally created by Harvey Dubner in 1963. Julian Braun made some refinements, then Edward Thorp
published the system in his book Beat the Dealer (which is considered by many to be the first card counting
book.) It was then further refined by Stanford Wong and published again in the book Professional Blackjack.
How to Count Cards Using the Hi-Lo System
We wrote extensively about card counting in general on our main card counting page, but in brief, here’s how
it works:
Card counters track the ratio of high cards to low cards left in the deck so that they can raise their bets when
the odds are in their favor. When a deck has a relatively high number of aces and 10 cards in it, you’re more
likely to be dealt a blackjack (or a “natural”) and receive the 3 to 2 payout. If you don’t understand why this
works, try a little thought experiment:
Take a deck of cards, and remove all the cards that aren’t aces or 10s.
Do you think you’d be more likely to be dealt a blackjack with that deck?
Of course you would, and the reasons are obvious.
But the reality is that every card dealt out of the deck affects those odds. If you can keep a rough estimate
going of that ratio, you’ll know when to raise your bets and by how much.
So every card in the Hi-Lo System is assigned a value, and as you see each card, you add or subtract that value
in order to maintain a running count.
Here’s the value assigned to each card in this system:
- Aces and 10s are worth -1.
- 2s, 3s, 4s, 5s, and 6s are worth +1.
- 7s, 8s, and 9s are wordth 0.
You might notice that there are 20 cards worth +1 (4 of each rank.) There are also 20 cards worth -1. (4 aces,
4 jacks, 4 queens, 4 kings, and 4 10s.) Since the cards are assigned values of +1 and -1, and since there are
the same number of cards of each value, this is called a “balanced count”. If you count through an entire deck
https://luckymove.netlify.app/free-online-casino-table-games-no-download.html. of cards using this system, you’ll end up with a total of 0. That’s true of any balanced counting system.
You’ll also notice that you’re only required to add 1 or subtract 1. There aren’t cards worth 2 points or 3 points.
This is what card counting experts call a “single level” system. More complicated card counting systems will
sometimes assign different scores to different cards. We know of one system that assigns half points to some
cards.
The goals of these unbalanced and multi-level systems are to increase the accuracy with which you can gauge
your edge against the casino, so you can make more appropriately sized bets. They also provide you with
more accurate information you can use to adjust your strategy decisions based on the count.
that still provides the counter with an edge over the casino. In
this respect, it works admirably.
Converting the Running Count Into a True Count
If you’re playing in a single deck blackjack game, you don’t have to worry about this. Your running count is a
more-or-less accurate representation of how good or bad the deck is.
But not all games are single deck games.
In fact, most games use 6 or 8 decks.
Since there are so many more cards in a pack with multiple decks in it, the effect of each card that’s dealt is
diluted.
Here’s why:
If an ace is dealt out of a single 52 card deck, you only have 3 aces left. That’s a significant change.
But if an ace is dealt out of a pack of cards using 8 decks, you have 31 aces left in the deck. That’s a change,
but it’s not nearly as significant.
To take into account this dilutive effect, you take the running count and divide it by the number of decks left
in the shoe.
This is a skill you’ll need to practice, too—estimating the number of decks left in the shoe.
Our AdviceThe only way to get good at this is to practice, and we suggest practicing at home rather than practicing at
the casino when real money is on the line.
Bet Sizing Using the Hi-Lo System
Most of the edge to be gained from using the Hi-Lo System comes from sizing your bets. To do this, you decide
on a betting range in units before sitting down to play. We’ve seen recommendations that you range your bets
from 1 unit to 4 units, but we’ve also seen recommendations that you be willing to bet up to 10 units.
The reason for using a more conservative max bet is to reduce the chance of getting heat from the casino. Pit
bosses and dealers are aware of how card counting works, and when they see a player ranging her bets wildly,
they start watching to see if you’re counting. If they think you’re counting, they’ll start shuffling every hand.
Or they might even ask you to not play blackjack or even leave the casino entirely.
At any rate, you size your bet based on the true count, not the running count. You start with a single unit, then
multiply that by the true count to get your bet size. But you never go over whatever max you’ve decided on
beforehand, regardless of the count.
- If the count is negative, 0, or 1, you’ll flat bet with your minimum bet.
- If the count is +2, you’ll double that bet size.
- If it’s +3, you’ll triple that bet size.
An so on.
If your betting unit is $100 per hand, you’re looking at betting $200 when the count is +2, $300 when the
count is +3, and so on.
This single change to your playing strategy will give you an edge over the house, assuming that you’re already
playing with basic strategy and not making any other changes.
No Card Counting
In fact, this system is excellent at determining when you should raise your bets and by how much. According
to QFIT, the betting correlation for this system is 0.97. (1 would be perfect.) It’s hard to get much better than
that.
On the other hand, some card counters also like to get an edge by adjusting their basic strategy decisions
based on the count. The Hi-Lo System is significantly less effective for this purpose, with a playing efficiency
score of only 0.51.
Summary
The Hi-Lo System is probably the easiest and most common card counting system in use, and
https://luckymove.netlify.app/citizens-of-earth-casino-canyon.html. it’s perfect for beginners. If you decide you want to try counting cards, the Hi-Lo System
is probably the best place to start.
You get an edge with a simple method of calculating the approximate ratio of high cards to low
cards in the deck. All you have to do is add 1 and subtract 1 at the appropriate times.
Then you convert that running count into a true count. The true count is what determines
how much you should bet per hand. The increased likelihood of having more money in action
when you have a better chance of getting dealt a blackjack and the corresponding 3 to 2
payout is where you get your edge.
The Hi-Lo System isn’t the best for informing changes to your basic strategy decisions, but
that’s not where most of your edge comes from anyway. Even experienced advantage
gamblers like David Sklansky recommend using the Hi-Lo System for counting
cards in blackjack.
Card Counting Systems > Hi-Lo Count
The Hi-Lo Count may be the most widely known count in blackjack, and is a count that most serious card counters have used at one point or another. It is a more robust system with a greater potential profit than the Ace-Five system; however, it is also more complex, and more prone to detection, since you’ll be making more adjustments to your play.
In the Hi-Lo Count, each shoe starts with a count of 0. Red flush casino 50 free spins. The player must be very aware of the cards coming out of the shoe, because this count will change rapidly. The cards in the deck have the following values:
Card Value | 2,3,4,5,6 | 7,8,9 | 10,J,Q,K,A |
---|---|---|---|
Count | +1 | 0 | -1 |
Obviously, high cards – tens and aces – are good for the player, while the lowest cards are bad for the player. Free slot games for mac. As cards come out, add and subtract according to the chart above, keeping what’s known as the running count.
Here’s where things get a bit complex. You’ll need to divide that running count by the number of decks remaining in the shoe to get a true count. This is not simple to do precisely, especially when you’re first starting out. However, you can get most of the benefits of the Hi-Lo system simply by estimating this number to the best of your ability. Try to get it to the nearest deck; if a game starts with eight decks, you should be roughly aware when about 52 cards have come out of the deck, which would mean that there are now seven decks left, and so on.
As with most card counting systems, you’ll want to start with a small bet (like the table minimum). If the true count is at +1 or better, you have the advantage, and can begin increasing your bets. Many different books and writers suggest different ways to increase your bets, but of course, avoiding detection is also important, so following a set system may not be the way to go. One popular method is to only raise your bet when the count is both in your favor and you’ve just won a hand. Conversely, you might want to wait to drop your bets until you lose a hand, even if the count has gotten bad. Even if it eats into your profits slightly, avoiding detection is worthwhile.
One of the great things about the Hi-Lo count is that, since it is counting tens in addition to aces, it gives you a chance to make more strategy adjustments than you can when using a simpler count like the Ace-Five. One of the major adjustments to make is to start taking insurance when the true count is at +3 or higher. This is actually a large part of the advantage you’ll get over the house, since you’ll be able to make profitable insurance bets. More advanced Hi-Lo systems will also allow you to surrender additional hands, and even play hands differently than basic strategy dictates depending on the true count.
Depending on the exact rules used, how much of the advanced playing adjustments you use, the bet spread you’re comfortable with and how much cover you have to use to avoid being detected, the Hi-Lo Count has the potential to give greater rewards than the simpler Ace-Five count. In most cases, the advantage will range anywhere from .5% to 1.2%. This may not sound like a lot, but it’s actually a fairly significant advantage – often more than the advantage the house has when you simply play with basic strategy.
Even more complex systems exist, but if you can master the Hi-Lo count, chances are that you’ll be handle most systems you’ll find in blackjack books. It will give you practice making strategy adjustments, keeping both running and true counts, and avoiding detection by casino personnel – making it the perfect way to jump into serious card counting.
