Understanding Card Counting in Blackjack: A Comprehensive Overview and Fundamentals
On this page
Introduction
Let me emphasize that mastering card counting can be quite challenging, and it doesn’t necessarily provide the financial rewards depicted in films and TV shows. If counting cards were a foolproof method for earning money, the game would be overrun by players.
Without a solid understanding of basic strategy, attempting to count cards could lead to poor decisions. Even seasoned card counters primarily rely on basic strategy most of the time. There’s no shortcut in mastering the basic strategy; those who skip this essential step will likely find themselves at a disadvantage.
To excel as a card counter, one must quickly assess the values of cards in play and commit a large number of numerical strategies to memory while maintaining a façade of being a casual player. Moreover, with the current rules in place, a realistic edge for counters ranges from just 0.5% to 1.5%. So rather than a gradual, consistent winning streak, your bankroll will fluctuate dramatically in the short term. It is only after hours and hours of play that you may expect to see a profit.
The foundational concept of card counting lies in recognizing that a deck rich in tens and aces favors the player, while a deck filled with smaller cards benefits the dealer. When counters determine the odds are skewed in their favor, they will increase their bets and modify their strategies, sometimes choosing to stand, double, or split in ways that deviate from basic strategy. Having a deck laden with tens and aces tilts the options available to the player even further in their favor. Here’s a quick overview of those situations.

Standing : Players can stand with stiff totals ranging from 12 to 16, whereas dealers cannot. In ten-heavy decks, hitting stiff totals becomes riskier, making it wise to adopt a more conservative strategy.
Insurance : Generally, when the dealer shows an ace, the odds indicate that around 30.87% of the remaining cards will be tens (in a six-deck setting), which renders insurance a poor bet. It only becomes favorable if the probability exceeds 33.33%. Counters are aware of when the deck is ten-rich, allowing them to place strong insurance bets at those opportune moments.
Doubling : When players choose to double, they often hope for a ten. In ten-heavy decks, this increases the likelihood of favorable outcomes and getting closer to 21.
Blackjack : Both the player and dealer may encounter more blackjacks; however, the player enjoys a better payout of 3 to 2, while the dealer does not.
Surrender : Opting to surrender becomes a more attractive choice in ten-heavy scenarios, as avoiding hitting is often riskier. If players would otherwise stand, the dealer has a higher chance of drawing a ten. Consequently, counters are likely to surrender more frequently when the count is high, leading to significant savings.
Splits : Players typically split high-value cards or those against weaker dealer cards. Regardless, in a ten-rich deck, their chances of achieving higher totals and inducing busts in the dealer increase.
I am in the process of conducting a thorough analysis of how these factors interact. Each factor’s contribution varies based on the specific rules, deck penetration, and bet spread. Nevertheless, based on the average conditions found in a six-deck shoe, my preliminary findings outline the advantages of card counting as follows.
Why Card Counting Works
| Player Option | Portion of Benefit |
|---|---|
| Stand | 40% |
| Insurance | 34% |
| Double | 9% |
| Blackjack | 7% |
| Surrender | 6% |
| Split | 4% |
The statistics regarding insurance have been derived from Don Schlesinger’s "Illustrious 18" guide. Blackjack Attack . The rest of the breakdown is mine.
To evaluate the abundance of high cards in the deck, players monitor which cards have already been played. Strategies differ, but they all typically assign a numerical value to each card. For instance, a common approach, the hi-lo count, assigns +1 to cards 2 through 6 and -1 to tens and aces, with the rest holding a neutral value of 0. At the start of a deck or shoe, the count begins at 0. The counter then adjusts this count up or down as cards are revealed, resulting in a "running count." A positive count suggests that a disproportionate number of low cards have been dealt, indicating a deck rich in high cards. To compute the "true count," simply divide the running count by the number of decks remaining or, in some methods, the number of half decks. This helps assess how likely it is that the deck contains good cards.
The true count serves a dual purpose: it guides both betting amounts and hand play decisions. In most scenarios, there exists a threshold that dictates different actions based on whether the count surpasses that threshold. For example, if a player has a total of 12 facing a dealer’s 6, they may decide to stand for true counts of -1 or higher while choosing to hit with counts lower than -1. Additionally, when the true count is elevated, indicating a favorable deck, counters are inclined to increase their bets accordingly.
A key challenge arises regarding how to account for aces. Players should ideally wager more when aces are plentiful since they enhance the chances of achieving a blackjack. However, regarding gameplay, the number of aces is often less critical than the number of tens, so while it's beneficial to track both, it's not strictly necessary. Certain counting systems maintain a separate count for aces. For instance, in the Hi-Opt I and Revere Plus/Minus systems, aces are tracked independently and are considered mostly during betting decisions. This method is generally more precise and effective than providing aces a negative value without a side count, which is common in some strategies. Yet, many experts believe that beginners might find keeping two separate counts overly complex, thus increasing the risk of errors which could be costly. Strategies that do not track aces separately may yield slightly lower efficiency, but the reduced chance of mistakes often outweighs this. Different experts offer varying opinions on what beginners should pursue. The Zen Count strikes a middle ground, assigning a value of -1 to aces and -2 to tens. From personal experience, I would advise against counting strategies that require a separate ace count for those new to card counting. The Uston Advanced Plus/Minus is a recommendable approach without an ace side count and can be found in various literature.

Legally, players can engage in Blackjack through any means that do not involve cheating or computer assistance, while casinos have the right to implement measures to deter anyone they identify as having an advantage. Much of the difficulty in card counting arises from avoiding the perception that you’re anything but a regular player. A major tell that someone is counting cards is a marked increase in bet size after a string of lower-valued cards has been dealt. While multiplying your bet size can enhance your winning chances, doubling it abruptly can quickly raise suspicion from the dealer or pit boss. Often, once casino staff realizes you're counting cards, they’ll shuffle the deck each time you increase your wager, thereby negating your advantage or even ask you to leave the premises.
