Using Splitting Pairs in Blackjack to Reduce the House Edge


Blackjack is a game of chance and luck, but the house edge can be brought down to 2% by following a specific strategy. The game’s appeal mostly lies in its simple rules, which have remained unchanged worldwide.

While these rules may not be perfect, they will get you pretty close. And they are much easier to remember than perfect blackjack strategy.

Game rules

Blackjack is a card game played by one or more players against the dealer. The objective is to beat the dealer by getting a hand value of 21 or higher without going over it. The game also features bonuses for specific hand values, such as jack of spades and ace.

During a blackjack game, the player and the dealer each receive two cards. One of the dealer’s cards is dealt face up, and the other is hidden. If a player’s unbusted hand is greater than the dealer’s, they win and are paid 1:1 odds.

Players should avoid touching their cards to prevent suspicion of tampering or marking. Instead, they should use one hand to indicate their intentions. This etiquette is important because it maintains the integrity of the game and protects other players.


Blackjack is a game of strategy that requires a certain level of concentration and the ability to make clear decisions. Responsible gambling is essential for winning at blackjack, and it involves setting a budget and playing within that limit. It’s also important to stay sober and not make decisions based on your feelings. In addition, it’s best to avoid deviations from the basic blackjack strategy.

Another important tip is to leave personal items, such as bags and drinks, off the blackjack table. This helps maintain the professionalism of the game and keeps the table uncluttered. It’s also good etiquette to tip the dealer. Like bartenders and waiters, dealers often rely on tips to earn their living. However, don’t tip excessively. A small tip is generally sufficient.


Insurance is a side bet that is available in blackjack. It pays out 2:1 if the dealer has an ace. It is a good option for card counters because it can improve the odds of getting a blackjack in a given game. However, it’s not a good idea for everyone.

Taking even money isn’t always a good idea, especially on tables that pay blackjacks 3 to 2. This shortcut can strain your profits over the long run, so avoid it if possible.

The Insurance bet is not a smart move for any player, and it should be avoided in most cases. The fact that you can lose your Insurance bet and your original bet is reason enough to give it a wide berth. Moreover, it does not lower the house edge, so it is not worth your time and effort.

Dealer’s face-down card

When the dealer deals their first card the player can either signal they want to hit or stand. Then the dealer flips a second card and slides it underneath the first. The player then decides whether to take Insurance. If they do, they place an additional bet equal to half their original bet. They win if the dealer has Blackjack but lose their original bet if they don’t.

If the dealer has a face up card of ace, players can make side bets of up to half their original bet that they believe that the hidden card is a ten. The dealer then checks their hole card and if it is a ten, all bets push. If not, the dealer exposes their other card and the players continue to play their hands.

Splitting pairs

Splitting pairs in blackjack is a powerful strategy that can reduce the house edge by as much as 0.57%. It can also give players a better chance of winning when their starting hand is weak. However, it’s important to understand when to use the strategy and when to avoid it.

For example, you should never split a pair of nines because they are already 18 points and only need an ace to become a good hand. But you should split a pair of eights against a dealer’s two through six, as this will improve your odds of winning. You can also double down on these hands, although this is not always a good idea.
