Misplaying paired Aces is one of the most common mistakes among blackjack rookies which ultimately causes them to lose money in the long term instead of profiting. This article teaches you how to approach a pair of Aces optimally and explains when and why you should refrain from splitting them. Casino Rules on Splitting Aces. Blackjack Two Aces, why is ho chunk casino taking out the good machines we like meme, zynga poker unblocked, meilleur site roulette en ligne. If you play your two aces as one hand, you'll start with a value of 12 (one is played as an 11 and the other as a one). Only a nine will give you 21. A 10 or face card will force you to play the second ace with a value of one, bringing you back to 12. The input of my example is a list of 3 Aces. Where there is an API that evaluates each Ace and returns a list of two values (1,11) for each Ace. So the input becomes something like Z = ((1,11),(1,11),(1,11)). And the output should be all possible sum combinations of Z. Note that the input number of Aces.
Ace-seven is by far the most difficult hand for the professional blackjack player to handle. Depending on what the dealer is showing, you will either hit, stand, or double down.
Basic Strategy tells us that we should double if the dealer is showing 3 through 6, stand on 2, 7, and 8, and hit on 9, 10, and A. This may come as a shock to some since common sense tells us to stay with an 18 regardless of what the dealer has. Let's look at the math behind the strategy.
First, we must look at A-7 as a plain old 18. Basic Strategy dictates that we stand on a pat 18 regardless of what the dealer is showing; we want to get to 17 or higher and then let Lady Luck determine the outcome. This isn't necessarily the case for a soft 18. Jackpot capital $100 no deposit bonus codes 2020.
- If the dealer is showing a 2, the return on an 18 is $.12 for each dollar invested.
- For 3 through 6, this jumps up ranging from $0.40 to $0.50 per dollar.
- 7 is also $0.40.
- At 8, it goes back down to $0.11.
- 9 through A plummets into a negative return of $0.18 to $0.10 loss per dollar.
So is it really worthwhile to go against the common sense factor and hit an 18 if the dealer is showing 9-A?

- Hitting A-7 on a dealers 9 gives us a negative return of $0.10,
- 10 a negative return of $0.14, and
- Ace a negative return of $0.09.
The spread here, while not seeming like much, is less than the -$0.18 to -$0.10 return of staying. To minimize the damage, hitting on these cards is a necessity.
Doubling is the third option with this hand. In this case, you count the hand as an 8 and pray for a 9 or 10, or you count it as an 18 and hope for an Ace through 3.
First of all, doubling when the dealer is showing:
- 9 through A gives us a -$0.29 to -$0.36 return, far greater of a loss than hitting. So doubling on those cards is out of the question.
- Doubling on 8 is also a negative return (-$0.03), whereas it's a positive return to hit. Again, out of the question.
- Doubling on 7 is a positive return of $0.22, which is less than the $0.40 you will get with staying. If the dealer is showing a 7, it makes economic sense to stand.
- Doubling on the dealer's 2 is also $0.12 return, but it is less than a cent less difference of a return than standing. In the long run, this adds up to major dollars, believe me. You will want to stay rather than risking the double in this case.
- That leaves 3 through 6. The math here gets tricky, so pay careful attention. The numbers above regarding standing on 18 don't take into account the power of the Ace. As you know, the Ace can be counted as either a 1 or an 11, and because of this, hitting on A-7 is not nearly as dangerous as hitting a pat 18. In fact, the 23% (3/13) chance of drawing a card to better your 18 makes the diminished return on doubling the right move.
While the return ranges from $0.18 to $0.38 (compared to the $0.40 to $0.50 of staying), the 23% odds of improving plus the doubled amount of money pumped into the hand make doubling the most profitable choice.

Two aces and two eights in a standard deck of playing cards.
Splittingaces and eights is part of blackjackbasic strategy. Rules vary across gambling establishments regarding resplitting, doubling, multiple card draws, and the payout for blackjack, and there are conditional strategic responses that depend upon the number of decks used, the frequency of shuffling and dealer's cards. However, regardless of the various situations, the common strategic wisdom in the blackjack community is to 'Always split aces and eights' when dealt either pair as initial cards.[1] This is generally the first rule of any splitting strategy.[2]
Splitting[edit]
The object of blackjack is for a player to defeat the dealer by obtaining a total as close to 21 as possible without accumulating a total that exceeds this number.[3] In blackjack, the standard rule is that if the player is dealt a pair of identically ranked initial cards, known as a pair, the player is allowed to split them into separate hands and ask for a new second card for each while placing a full initial bet identical to the original wager with each. After placing the wager for the split hands the dealer gives the player an additional card for each split card. The two hands created by splitting are considered independently in competition against the dealer.[4][5] Splitting allows the gambler to turn a bad hand into one or two hands with a good possibility of winning. It also allows the player to double the bet when the dealer busts.[2] Some rules even allow for resplitting until the player has as many as four hands[4] or allow doubling the bet after a split so that each hand has a bet double the original.[6][7] The standard rules are that when a bet is doubled on a hand, the player is only allowed to draw one more card for that hand.[8][9] Springbok casino new free coupon.
Aces[edit]
A pair of aces gives the blackjack player a starting hand value of either a 2 or a soft 12 which is a problematic starting hand in either case.[2][10] Splitting aces gives a player two chances to hit 21.[11] Splitting aces is so favorable to the player that most gambling establishments have rules limiting the player's rights to do so.[2][10] In most casinos the player is only allowed to draw one card on each split ace.[8][10] As a general rule, a ten on a split ace (or vice versa) is not considered a natural blackjack and does not get any bonus.[6] Prohibiting resplitting and redoubling is also common.[2] Regardless of the payout for blackjack, the rules for resplitting, the rules for doubling, the rules for multiple card draws and the dealer's cards, one should always split aces.[10][12][13]
Eights[edit]
If a player is dealt a pair of eights, the total of 16 is considered a troublesome hand. In fact, the value 16 is said to be the worst hand one can have in blackjack.[10] Since sixteen of the other fifty cards have a value of 10 and four have a value of 11, there is a strong chance of getting at least an 18 with either or both split cards. A hand totaling 18 or 19 is much stronger than having a 16.[6] Splitting eights limits one's losses and improves one's hand.[10][11][12] Probabilistic research of expected value scenarios shows that by splitting eights one can convert a hand that presents an expected loss to two hands that may present an expected profit or a reduced loss, depending on what the dealer is showing.[14] 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.[15] 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.[16]
History[edit]
Blackjack's 'Four Horsemen' (Roger Baldwin, Wilbert Cantey, Herbert Maisel and James McDermott), using adding machines, determined that splitting eights was less costly than playing the pair of eights as a 16.[17] They were part of a 1950s group that discovered that strategy could reduce the house edge to almost zero in blackjack.[18] Now a typical strategy involves the following sequence of playing decisions: one decides whether to surrender, whether to split, whether to double down, and whether to hit or stand.[19]
One of the earliest proponents of the strategy of splitting eights is Ed Thorp, who developed the strategy on an IBM 704 as part of an overall blackjack strategic theory published in Beat the Dealer: A Winning Strategy for the Game of Twenty-One in 1962.[18][20][21] Thorp was the originator of the card counting system for blackjack.[18]
