When a player receives a pair of cards with the same value, the house allows the player to opt for a blackjack split. This option means that the player can separate the cards and treat each card as a part of two independent hands.
If you receive, for instance, a pair of 5s, you can split the cards, place a bet of the same amount as the original bet, and ask for cards to pair each separated card.
Blackjack split, however, cannot be treated as blackjack. Say, if you have a split pair of 10s, and gets an Ace to pair one of the cards, the new hand (10 and Ace) cannot be considered as a blackjack.
Before opting for blackjack split, however, you still have consider what are your chances of beating the dealer if you do or do not make that move. When is blackjack split a good gambling option?
First, take a look at your cards, and take a look at the dealer's up card. Then, make your move.
Split a pair of aces--- for the obvious reason that two Aces is a bust.
Split a pair of 8s and treat each hand independently.
Against a dealer's up card of 2 through 7, split a pair of 2s and 3s. Otherwise, better make a hit.
Against a dealer's up card 4 or 5, separate two 4s. If not, draw another card.
If the dealer has an up card of 2 through 9 and you have a pair of 5s, don't split your cards. Double down instead. If the dealer has cards other than 2-9, hit is a better option.
Against a dealer's up card of 2 through 6, split a pair of 6s. If not, opt for a hit.
Against a dealer's up card of 2 through 7, split two 7s. If not, opt for a hit.
Against a dealer's up card of 2 though 6, 8, and 9, split two 9s. If not, hit is a wiser option.
A pair of 10-valued cards is a good hand. So splitting such a pair is a bad play. Rule of the thumb is, stand on two 10s.
If you, for instance, split a pair of 4s and draw another four of your card, the house may allow you to re-split. Some casinos, however, limit the number of blackjack splits they allow a player to take. Some casinos have other rules as well for blackjack split such as No Ace Split. It is important, therefore, to know the house rules before sitting down the gambling table.
In order to signal your intent to make a blackjack split, place your new bet adjacent to the original bet, then place your cards face up near your bets.
Through a game option known as blackjack split, when you have two cards of the same value, a player is allowed to separate the two cards into two independent hands. When played strategically, blackjack split can maximize your chances to beat the dealer down the card table.
