Splitting[edit]

Blackjack Split Rules

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]

Aces[edit]

Splitting is allowed when you get pairs in your initial hand (5-5, 6-6, etc.). Depending on the Blackjack game you play, you can split more than once during the game, split Aces, etc. This is a good move in some situations. To use this move to your benefit, you should consider the. Always split Aces and 8s. The easy ones to remember: 2s, 3s, 7s – split when dealer shows 2-7; 6s – split on dealer's 2-6. And the unique ones: 4s – are not a perfect hand for splitting, so you should split them only when the dealer shows 5 or 6 and only when you can double after split.

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]

  1. Not every blackjack pair should be split, playing the single hand to the end might be to your advantage. That said, some pairs should almost always be split as, statistically speaking, doing so will result in losing less money over time or offers a reasonable chance of turning a losing hand into a winning one.
  2. If you stood against an 8 or a 9, then you're likely facing a dealer total of 18 or 19. You can only hope for a push in the first situation and a loss in the second, unless you split the cards and get lucky.

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]

Should

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] Difference between cash games and tournaments.
