In blackjack, "split" means to divide a pair of cards of the same value into two separate hands, then receive an additional card for each hand from the dealer. To split, the player must place an additional bet on the newly created hand that is equal to the original bet they placed at the start of the game. The split is offered when a players initial two-card hand includes two cards of the same value.
Splitting can be a favorable move in certain situations, but it is not always the best option. For example, it is always recommended to split a pair of aces. However, it is not recommended to split every single pair all the time, as the risk of losing twice as much is higher. The decision to split depends on the dealers up-card and the probability of winning. It is important to know the specific splitting rules at the table being played, as some tables only allow one split while others allow multiple splits.
