The majority of blackjack games allow you to split pairs of the same value. This allows you to play with two new hands, and thus, more chances to win. Experts always recommend you split Aces and re-split them if the game allows it as they can have the most value. Eights are another pair worth splitting because the dealer is more likely to stand on 16. Nines and tens aren’t usually worth splitting if you already have a strong hand.
