Blackjack is a game of chance, but it is also a game of strategy. This means that a player’s decisions, the way they handle their hands can affect their edge against the casino and ultimately the game’s outcome.
A piece of advice that every newbie blackjack player would almost certainly receive from a more experienced counterpart would be to always split 8s. But why has this become a common blackjack wisdom that has long been spouted by expert players?
In this article, Casino News Daily intends to delve deeper into why it is a good idea to split 8s and why it has become a classic defensive move in basic strategy play.
Worst Hand in Blackjack?
When a player visits a land-based casino or an online casino to play blackjack, they certainly want to make sure they are doing their part to increase their chance to prevail over the house.
To basic strategy players, splitting 8s is a rule they always follow not because it is a great move, but it is a move that would reduce their net loss in the long run. But more about this later.

Many would say that there isn’t a worse hand to start a blackjack round with than a hard total of 16. In a land-based casino, you could almost certainly see a blackjack player shift uncomfortably in their chair if they get to start a game with a hard 16.
This is because there isn’t really a good way to play a hard 16 and win. If a player chooses to stand, the chance for the dealer to beat them with a higher total is pretty solid. And if they choose to hit, they will probably bust.
If dealt a pair of 8s, it is always a good idea to split them and thus replace a bad hand with two average hands.
Why Do Blackjack Basic Strategy Players Always Split 8s?
Splitting 8s is very much a move that basic strategy players swear by. This is because two hands starting with an 8 each isn’t nearly so bad a start to a new blackjack round as a hard total of 16.
Many could argue that splitting is bad because it means the player must put another bet of the same value on the table. However, it is actually pretty easy to explain why two hands starting with an 8 have a lot more potential than a hard 16 as there is a very understandable logic behind this classic basic strategy defensive move.
Basic strategy assumes that 10s would be drawn because there are more of these in play than any other card value. In other words, splitting 8s offers players the chance to get two hands of 18. And 18 is a good, if not excellent, point value.
And if a player doesn’t get a 10, they could get an ace for a total of 19, which is, of course, an even better scenario.
Even if a player gets a 9, the hand improves to a total of 17, which, while not ideal, is a respectable hand.
After splitting there is still a chance that a player loses both new hands, but there is also a chance to win one and lose the other, or even win both hands.
It is believed that while splitting 8s is not a great move, it is a solution that provides players with the chance to improve a hard total of 16 and a solution that would see players fare better and lose less money in the long run.

Splitting Pairs
If a player has a 16 versus the dealer’s 10 with a $10 bet on the table, they would lose an average of 40 cents on that hand in the long run.
However, if a player gets a pair of 8s and chooses to split them, that makes two $10 hands starting with an 8 each. On average, the player would lose 16 cents on each of the two hands for a total loss of 32 cents. This shows that splitting 8s is saving players more money, even if both new hands lose against the dealer.
According to this chart, the only time when a player could act differently when dealt a pair of 8s is when the dealer hits on soft 17. In that case, the player may want to surrender, if allowed.
What Do Experts Say?
In 1956, a group of four mathematicians – Roger Baldwin, Wilbert Cantey, Herbert Maisel, and James McDermott – tried to solve every blackjack mystery by using desk calculators and running through the math each and every possible outcome.
The four scholars, known in the blackjack world as the Four Horsemen, concluded that splitting 8s is a move that has a lot more potential than hitting or standing on a hard total of 16.
Few people believed the Four Horsemen back then. However, Ed Thorp ran the same hand through his IBM computer six years later and confirmed the four scholars’ answer.
In his book Beat the Dealer, Thorp wrote that if a dealer has a 7, 8, 9,10, or an ace up, 8s should be split not that much because “a good total will be obtained, with each new hand, but rather because 16 is, in general, a bad total to hold.”
Thorp also noted that if a dealer shows a 2, 3, 4, 5, or 6, splitting the 8s gains in two ways – in the first place, two average hands replace a bad one, and secondly, “the dealer’s chances of busting is quite high with these up cards, and thus there is an advantage in getting more money onto the table.”
