Follow these strategic pillars to increase your chances of success and reduce the house edge when playing online blackjack real money games:
- Always double down on a hard 11
- Double down on 10 if the dealer has nine or lower
- Always split aces and always split eights
- Do not split 10s or fives
- If the dealer’s face card is two or three, hit a hard 12
- If the dealer has a nine, a 10-card or an ace, hit a soft 18
- If the dealer has a five or six, double down ace-two, ace-three, ace-four, ace-five, ace-six and ace-seven
- If the dealer has a seven, stand with a pair of nines
- If the dealer has a two or three, split twos or threes
Basic Blackjack Strategy
One of the reasons blackjack is so popular at the best NZ online casinos is because it’s easy to play and has a low house edge. However, a big caveat to the house edge theory is that the house edge only remains low if you play what is known as a “perfect game”.
Unlike most casino games, blackjack involves an element of skill. Or, at least, there is a method that will increase your chances of winning. Given that you have to make choices for each hand, these decisions can affect your overall chances of winning.
A blackjack strategy chart lets you see the correct play to make with every combination of cards you are dealt. It does this by considering the dealer’s up card and highlighting the action that will be most profitable. Yet, charts will go beyond simply saying to hit or stand.
Using a blackjack strategy chart is a straightforward process. You simply find the combination of cards you hold between the soft total, hard total, and pairs section and then match that up with the up card for the dealer. The chart will specify the move that you need to make.
A key to the table might look something like this:
- H = Hit
- S = Stand
- D = Double if allowed (otherwise hit)
- Ds = Double if allowed (otherwise stand)
- N = Don’t split the pair
- Y = Split the pair
- Y/N = Split the pair only if “DAS” is available
If you're playing online, you can keep the chart handy as you play. You’ll have time to check off the correct play. If you play live blackjack, some casinos will allow you to keep a chart at the table, and some might ask you to remove it. Either way, it will be massively beneficial for you to memorize the blackjack strategy chart.
We must add that this basic blackjack strategy chart that we have included is just the starting point. Depending on the house rules and the type of blackjack game you’re playing, you will need to alter your blackjack chart accordingly. Yet, these changes will be minimal, making memorizing it much easier when playing new games.
Advanced Blackjack Strategy
When most people think of a blackjack strategy, they think of hand charts. These charts are easy to understand, follow and implement, telling you what to do in every scenario. Additionally, many refer to these charts as “total dependent”, meaning the number on display is a representative of the total for the cards you have.
For example, if you have a six and five, you have a total of 11. If you have a seven and a four, you also have an 11. For these blackjack strategy charts, how the number comes about is irrelevant.
Composition Sensitive Hands in Blackjack
Composition-dependent or composition-sensitive takes this to the next level. Instead of looking at hands as total numbers, it also looks at how the numbers are made up.
Like the example above, several cards can create the same total in blackjack. One of the reasons players do this is so they have a better idea of what cards are left and how the blackjack odds would then reflect this.
Composition-sensitive hands are easiest to utilize in games with fewer decks of cards (ideally, a single-deck game). Ultimately, this makes tracking much more straightforward. It also makes factoring in a composition a bit more relevant.
Two main rules apply to this: the “Rule of 45” and the “Doctor Pepper Rule”. The Rule of 45 is linked to having a hand worth 16, usually made up of a 10 and a six. If the player is up against a dealer 10, then the chances are they will lose the hand.
They need a four or a five to have any luck here. For this, the player needs to see if they have any four or five in their hand.
They can also look at other hands at the table if possible. If many are already out, then the chances of them grabbing the card they need are reduced. Therefore, this would mean that, in this example, it would be better to stand, given that fewer cards you will need to win are available. This is something that a traditional hand chart does not include.
How the hand is made up is another key factor here. It can include 10/2, 9/3, 8/4 and 7/5. A 10 is the only bust card, so when you’ve got one in hand (with 10/2), it’s one less in the pack that can bust you.
For this reason, you should hit when you’ve got a 10/2 in the hole against a four. For all other combinations, you should stand.
Blackjack – When to Double Down
Double down is one of the key plays in blackjack. This blackjack strategy is one of the only times you can get extra funds in the pot when you’re in a favourable position. You need to be aware of table rules about doubling down, but most will allow you to use this as and when required.
One of the most common times you will double down is when your cards total 11. This total is the best combination hand in the game, as many cards can either get you to 21 or get you somewhere near that will pressure the dealer regardless of their hand.
Next, you want to be targeting soft 16, 17, and 18. These hands are generally based on the dealers’ up card. If it is low, you can double down here. Many people look at 16, 17 and 18 as solid hands.
Therefore, they are inclined to stand. However, when dealers have low cards in the hole, they are more vulnerable. They will need to take at least one more card, making them susceptible to going bust.
Given that our hands here are soft, there aren’t too many hands that can really hurt us. Even a soft 18 could turn a four, which would be the worst outcome, and you’d have 12 against a dealer’s hand that could well go broke.
The final time we want to double down is with a hard nine or 10 against a low dealer card. This hand has the same merits as the soft hands above. But with this, there are lots of mid-high cards that make ours very strong. Again, the dealer also has a good chance of going broke, so we are always in the game here.
When to Split in Blackjack
There are two scenarios where you want to be splitting every time in blackjack. The first one is when you get dealt two Aces. While this is quite rare in blackjack, you want to split and try to create two big hands when you do.
By utilizing this blackjack betting strategy and spilling, we get not one but two chances to do this. If we leave them together, then we have 12 or two. Very few hands help here, so splitting is ultimately the best route.
The second is when we receive two eights. For this, we need to take note of the table rules and see what the dealer stands on. If they stand on 16, then the best outcome you have is hoping they bust.
If their hand plays, then at best, you can split. By splitting, you can still make two strong hands. Any 10 or nine card has the player as a big favourite, with Ace, two and three still more than enough to take another card.
When to Hit or Stand in Blackjack
The two most common decisions you will have at a blackjack table are whether to hit or stand. Timing is vital, but one of the biggest blackjack strategy tips we can give is to make sure you consider the dealer’s up card.
One of the biggest mistakes players make is they get too transfixed on what their cards are and how close to 21 they can get. Yet, in reality, the skill of knowing when to hit or stand is all about what the dealer holds.
There are dozens of blackjack strategy charts that you can use to know when to hit and stand. They allow you to not only see your cards but also the dealers’ up card. By following these charts, you can play the game as optimally as possible.
It’s also essential to take into account composition-sensitive hands. Doing so will allow you to take your game to the next level and work on a much more professional basis.
When Should You Surrender in Blackjack?
Surrendering is a blackjack strategy that many people try not to use. However, it’s worth remembering that the casino’s house edge will increase if you don’t surrender at the appropriate time.
The tips and tricks in this blackjack betting strategy require timing. Therefore, you need to be able to work out when and where is the best time to surrender.
To surrender is to forfeit half of your stake in your hand if you’ve little chance of winning. There are generally two types of surrender: early and late. Early is less common, as you get to decide before the dealer checks for blackjack. If you get access to the option, take advantage of it. Ideally, you want to be on the lookout for an Ace or a 10 from the dealer.
You should surrender early if you hold a hand that includes a hard five to seven, hard 12 to 17, threes, sixes, sevens and eights if the dealer has an Ace. You should also surrender early if you have a hard 14 to 16, sevens and eights if the dealer has a 10.
This may seem like a wide range of hands, but by implementing this correctly, you can reduce the house edge by 0.24% to 0.39%. Given blackjack only has an overall edge of around 1%, this is huge.
Late surrender is much more common, made when the dealer has checked for blackjack. Surrenders for this are generally only made with hands made up of 14, 15 and 16. The number of decks matters here as well. Still, here are several rules to note:
- 14 – single deck surrender to a 10.
- 15 – single or double deck surrender to an Ace.
- 16 – single or double deck surrender to dealer Ace and 10.
When to Take Insurance in Blackjack
But if you're wondering when you should take advantage of this blackjack option, the answer is never. Don't take insurance!
Why? Well, the numbers are massively in the casino’s favour here. You see, insurance will pay out at 2:1 for a successful bet. But the odds of the dealer making blackjack is 9:4. Ultimately, the house edge on the insurance bet can go between 5.8% and 7.5% which is definitely not in your favour.
Online Blackjack Side Bets
Speaking of side bets, you have various side bets to choose from with blackjack, but most are pretty rare. Yet, as a general rule of thumb, these should almost always be avoided. For example, some carry a huge house edge, offsetting any low edge from the main game.
One of the most popular bets is that of 21+. In this game, you're looking at hands that create a flush, straight, pair and combinations of each from the players’ two and the dealers’ one card. The house edge for this bet is a massive 8% in games played on four decks. This edge decreases with the more decks that are in play. You’ll find that this is a common theme with side bets.
If you’re looking to go pro, these are the wagers you should avoid. You would be far better off nailing a blackjack strategy from within the main game than messing around with side bets that may offer you little value in the long run.
