The Ace is a powerful tool for any successful hand because of its unique flexibility to count as either one or 11 points, at the player’s discretion. All learned blackjack players know we need to use this card wisely, and not let it go to waste.

It’s good to know these symbols if you’re unfamiliar, but in terms of Blackjack, the suit of cards are totally irrelevant. For each suit, there are nine numbered cards, 2 through 10, and four face cards, a King, Queen, Jack, and an Ace. That’s 13 cards per suit, but again, the suit isn’t important in. A split pair of eights is expected to win against dealer upcards of 2 through 7 and to lose less against dealer upcards of 8 through ace. If a player hits on a pair of eights, he is expected to lose $52 for a $100 bet. If the player splits the eights, he is expected to lose only $43 for a $100 bet. The last card - the Ace - has a special value in Blackjack. It can count as either 1 or 11, with the actual number being dependent on what helps out the most with a particular hand.

1 or 11 – How to Use an Ace

Required to form a natural two-card blackjack in all variants of the game (and thus a higher pay-out), the Ace is the pillar of the game of 21. A natural blackjack will always trump the dealer’s hand, or possibly force a push (otherwise known as a tie) if the dealer also draws to blackjack. And the Ace’s flexibility to be valued at either one or 11 points can be used according to which value is most advantageous for us, and this should not be taken for granted.

A hand with an Ace is known as a “soft hand” based on the fact that if we hit, we cannot bust. For example, if we hold an Ace/Four (five or 15 points in total) as our first two card dealt, it is impossible to bust by drawing another card, because if we drew a card valued at 10 points, we would simply give the Ace a value of one, for a hand total of 15. If we drew another Ace from the Ace/Four hand, such a hand could total either six or 16.

Drawing an Ace and a high-valued card such as a Seven, Eight or Nine give the player a strong starting hand, and needs to be played based on what the dealer is showing. It is important to play to the Ace’s strengths, but also be aware of the potential danger we face when the dealer shows an Ace; it’s equally as deadly a weapon when used against us.

If we draw two Aces, our first course of action is to always split them. While the Ace is a powerful card on its own, if we are dealt a pair of Aces on our first draw and opt to keep them together, their combined total value is either two or 12 points. While drawing another card would not bust our hand, starting with a soft-12 is a much poorer hand with much weaker odds of winning, than beginning afresh with two new hands which both have the potential to draw to blackjack.

While we are required to place another bet equal to our original wager when we split our cards, it is well worth the money, as we stand in a much stronger position than before. And should we win, the payout will be greater. Keeping the Aces together wastes the inherent value of the Ace card by itself. Always split them to have the best possible chances of bettering your hand.

The Catch With Split Aces

Because the decision to split a pair of Aces is universally agreed upon, because of the favourable odds such a move hands the player, casinos employ certain rules to counter its effectiveness.

• If we split our Aces and draw a 10-valued card to achieve blackjack with either hand, many land-based casinos enforce the rule that such a hand is not considered a natural blackjack, and therefore, we are not be entitled to the usual 3 to 2 payout; instead we only receive a 1 to 1 payout. We have more freedom playing online simply because of the vast range of different games with different rules, but there are still quite a few variants which enforce this rule, so be mindful of it before you let rip at not scoring a bigger return from your hard-earned 21.
• Another rule which can counter the effectiveness of split Aces states we are only allowed to be dealt one additional card to each Ace, with no allowance for hitting (just like if we were to double down). This significantly hurts our chances if we are dealt two lower cards, such as a Deuce and a Four, two our Aces, giving us totals of 13 and 15 respectively, and leaving us with no other option but to stand. Again, with the flexibility of online gaming, try to play games of 21 which do not own such a rule.
• One other rule which is far less enforced but still exists, is the simple rule which dictates players are not permitted to split Aces, full stop. There are subtypes of blackjack where this regulation is imposed. Steer clear of such games.

How to Maximise Our Aces

Using an Ace to its full potential is a key part of basic strategy. Whenever we are dealt an Ace, it is important to take note of the dealer’s up-card before we proceed (as it is with any other card). To understand what moves we should make with any hand containing an Ace, familiarise yourself with basic blackjack strategy here.

Exploiting an ‘Ace rich deck’ is a tactic used by many gamblers. A single standard deck has 52 cards, and there is one Ace for every thirteen cards. Should we be playing a single deck game, we should take note if no Aces appear in the first deal of 13 cards, or if even luckier, the second or even third deal of 13 cards. If such a scenario arises, we tend to call the deck an Ace rich deck, as none of the four Aces have yet been dealt.

If no Ace card shows in the first 13 cards dealt in a single-deck game, we should double our starting bet, and raise it again by around $5-$10 for every subsequent 13 cards dealt without an Ace. While this rare situation gives us only a slight boost in our odds, it should be taken advantage of whenever possible so as to potentially net us more bang for our buck.

She is a Beauty

We here at blackjack.com.au like to personify the Ace. Whenever we see that first letter of the alphabet appear on a card, we get excited, and more often than not, we reap the rewards of being dealt an Ace. So it’s only fair we pay tribute to her beauty. Her value is unique, akin to no other card, and in the game of blackjack, if we are ever so lucky to be dealt a pair of Aces, split them apart so they don’t get jealous of one another. Naturally, there is an increased risk when splitting, as we need to double our bet to create two hands, but she’s worth every penny.

Origins of the Ace

The term Ace first began in dice games rather than card games, and was used to refer to the side of the dice with only one dot. Ironically, in the earliest forms of card games and card gambling, the Ace was considered useless. It had the lowest value of all cards and was the worst one to draw. This is a far cry from its high value today.

When the French game of Vingt-et-Un (meaning twenty-one), came to America via French colonists, it helped to change the way Aces were perceived and used in blackjack, by shifting the previous perception of royal cards as being the best cards, especially following the beheading of King Louis XVI.

French gamblers, who felt it was politically incorrect for the royal cards to continue being considered high-value, replaced their crowns with personified representations of the ideals of democracy, liberty and honesty, while raising the Ace – considered now to be the personification of the common man – to the highest value. It has retained its status until this very day.

In order to understand how the best strategy is computed, lets have a look at the Blackjack rules. Blackjack is played with 1 to 9 decks of 52 cards each. The values of the cards correspond to their numerical value from 2-10. All face cards (Jack, Queen, King) count 10 and the Ace either 1 or 11, as the holders desires. A score with an ace valued as 11 is named soft-hand. A soft-hand score of 17 is denoted as 7/17.

The color of the cards does not have any effect.

The goal of the game is to reach a score (=sum of the cards) as high as possible but not more than 21. A Blackjack (Ace and a card whose value is 10) beats all other combination of cards. If the final sum is higher than the sum of the dealer, the player gets a play-off of 1:1 of his initial stake. If the players combination is Blackjack, the play-off is 3:2 of the initial stake. If the sum of the dealer is higher, the player loses his bet. If the sum is equal, then nobody wins. If the player holds a score of 22 or more, he busted and thus he loses his bet immediately. If the dealer busts, the players wins independently of his final score.

Blackjack can be played from one to seven players against one dealer. The dealer shuffles the cards. Now all the players must place their bets. Then each player and the dealer receives one card. The cards all lie face up. Thereafter the player receive a second card. The player now can continue to buy further cards, one by one, until he believes that he is near enough to 21. If the player believes to have reached a score high enough he must signalize the dealer to stay, which means not to ask for any further card.

Doubling down

The player has some more possibility's other than buy and stay. If he reached a score of nine, ten or eleven with his first two cards, he can double his bet. However if he does so, he will be dealt only one more card.

Splitting

If the first two cards are of the same value, the player has the possibility to split his hand, which means that each of the cards are used to start with a separate bet. For each split hand, an additional bet equal to the first is required. There is one exception: If the player splits two Aces, he receives only one more card and in such a case a score of 21 is not considered as Blackjack.

Dealers turn

Once the last player has decided to stay with his score, the dealer starts to draw a second card. If his result is reaching a score of 17 or more, he will deal himself no further cards. If the dealer has a score of 16 or less, he must draw until he has reached 17 or more. If the dealer exceeds 21, he busts. This is the basic knowledge You have: The dealer can not split nor double; he must play according to strict rules: Dealer must stand on all 17. That's the players advantage! On the other side, if both the player and the dealer busts, these scores are not considered as equal and the player looses his stake. That's the dealers advantage!

How to compute the correct strategy

The analyst sees the shoe as black box which computes him a probability for drawing a card of a certain value. Say we have 6 decks of 52 cards, so the probability of drawing an Ace is 6*4/6*52 = 24/312 = 7.7%. The probability of drawing a second Ace without reshuffle is 23/311 = 7.4% and so on. As the game goes on without reshuffle, the probabilities to draw certain cards will raise or decline, depending on which cards have gone in the past. From our point of view the shoe behaves like a wheel of fortune with varying distances between the nails.

The first thing to do, is to calculate the probabilities of the dealers last hand. This computation is straight forward as the dealer has no way of doing any decision. So it is quit easy to find out the probabilities of his final score.

The next thing is to find out the probabilities of what would be if ... . If the players score is 16, what's the probability of achieving 17, 18, 19, 20, 21 or busting. Probabilities also have to be calculated for splitting and doubling.

Because the player knows the dealers first hand before deciding what to do, he can compare the probabilities of the dealers last hand against the probabilities of possible final scores for each intermediate score he has. With this comparison, winning expectations can be calculated, gaining information about the best playing strategy.

Knowing the best playing strategy and knowing the probabilities for each final score, the dealer and the player will reach, the total expectation can be calculated. The total expectation is the magic number playing Blackjack. If it is below zero the player has to place minimum bets as with this card distribution he will lose on the long term. If however the total expectation is above zero (unfortunately thats quite rare) the player has to place high bets.

Interpret the strategy tables

For each decision a player can do the best strategy can be computed. There are 20 possible conditions where the player has to take decisions. These are:

• Buy or stay if the score is 12, 13, 14, 15, 16, 7/17 or 8/18.
• Double or buy, if the sum of the first two cards is 9, 10 or 11.
• Split, buy or stay, if the first two cards have the same value.

How Much Is An Ace In Blackjack

All these decisions depend upon the dealers first card, making a total of 200. There are some fundamental rules, which never change and must always be obeyed:

• Alway buy if the score is below 12.
• Always buy if the score is below or equal to 7/17. With a soft hand You can't bust, so there is no reason to stay if the score is 17 or less.
• Never buy if the score is 17 or higher.
• Never split 5-5. A score of 10 is a good point to start with, so use it.
• Never split X-X. A score of 20 is too good, to take any further risks.
• Never ever double a Blackjack.

For other decisions consult the expectation and probability tables computed on the Blackjack strategy pages.

Stakes height

The stake has to be placed before the player can see the dealers first card. So during that decision, very little information is available. The only information the player here, is the total expectation for the current card distribution in the shoe. If this is above zero, he shall place high bets.
