Like other casino games, blackjack is dependent on chance, but a player can increase their chances of success with an understanding of what strategies improve their odds. One such aspect in blackjack games is when or when not to split.
Splitting is allowed when the player’s initial cards are the same. Under some rules, they just have to be the same value, so any pair of face cards can be split. The player can double their wager and be dealt with an additional card to each of the original pair to form two new hands. Sometimes, the player will be dealt a twin pair again and may re-split. House rules vary, and it is up to the website to decide what they allow in their blackjack games.
Splitting is not always optimum. For example, with a pair of fives the player is better off doubling down. It is also generally better to keep a pair of tens with their score of 20 than risk a search for an ace. Conversely, a pair of eights should always be split as 16 is the worst initial score, and splitting aces gives a reasonable chance of gaining a blackjack hand.
