15 Blackjack Strategies You Must Know to Win

Henry Tamburin Ph.D is one of world’s most respected blackjack experts and a world-class player, and also the author of the Ultimate Blackjack Strategy Guide, and Blackjack: Take The Money and Run. In this article, he shares with us some of the best Blackjack strategies to use if you’re serious about the game and want to win more. Bear in mind that the strategies discussed in this video assume you are a recreational player, and not a card counter. The situations we’ll discuss in this video are as follows: Dealer must stand on soft 17 Dealer must hit soft 17 Doubling down after pair splitting is allowed Doubling down after pair splitting is not allowed Let’s begin…

Strategy #1: Always double down on a hard 11 You’ll always win more money if you double down on hard 11 against any dealer’s upcard instead of hitting in all games, with one exception.

If you are playing a multi-deck game at Oncasinogames where the rules specify that the dealer must stand on soft 17, you are slightly better off hitting against a dealer Ace rather than doubling down.

Strategy #2: Always split a pair of 8s and aces You should always split a pair of 8s and Aces regardless of what the dealer’s upcard is. Many players make the mistake of not splitting with a pair of 8s when the dealer’s upcard is a 9, 10, or Ace. They believe that because they are a big underdog in this situation, why bet more money by splitting? What they don’t understand is that you are less of an underdog by playing two hands, each starting with an 8 (when splitting), than you are playing one hand of 16 (and hitting). In other words, you will lose less money in the long run by splitting 8s against a 9, 10, or Ace than by hitting hard 16.

Bottom line: Always splitting 8s and Aces is your best strategy because in the case of Aces, it results in significant gains for the player, and for 8s, it will, based on the dealer’s upcard, allow you to cut your losses or win more money.

Strategy #3: Never split a pair of 5s or tens A pair of 5s is also a hard 10 and you are always better off taking a one-or-more-card draw to a 10 than splitting the 5s and playing two hands, each starting with a 5. Even though splitting 10s is much more often than not a winning play, keeping them together as 20 is an even greater winning play in all circumstances.

Strategy #4: Always hit a hard 12 against a dealer’s 2 or 3 upcard This is a situation where most players chicken out and stand on their 12 because they fear busting. The bottom line is this: against a dealer’s 2 or 3 upcard, you will lose money in the long run whether you stand or hit. However, you will lose less money by hitting (even at the risk of busting some of the time), which is why it is the best strategy.

Strategy #5: Always hit ace-7 (soft 18) when the dealer’s upcard is 9, 10, or ace A lot of players make the mistake of believing that a hand that totals 18 is a sure win, which is why they stand on soft 18 (A-7), especially when the dealer is showing a “strong” upcard (like: 9, 10, or Ace). The facts are these: when you hold an A-7 against dealer’s 9, 10, or Ace, you are the underdog whether you stand or hit. However, you are less of an underdog if you hit A-7.

This is because if you draw a small card (like: Ace, 2, or 3) you will end up with a pat hand that’s higher than 18, which will improve your chances of winning at blackjack. And if you draw any of the four ten-valued cards, you do no harm to the hand. Bottom line: Your best strategy is to always hit A-7 when the dealer shows a 9, 10, or Ace with a goal of getting to either a soft 19–21 or a hard 17 through 21.

Strategy #6: Always double down on 10 when the dealer’s upcard is 9 or less You are the favorite when you hold a two-card 10 against any dealer’s upcard of 9 or less, which is why doubling down is your best strategy. It’s a simple rule to remember: always double down on 10 when the dealer’s upcard is 9 or less.

Strategy #7: If the rules specify that the dealer must hit soft 17, you should always do the following: Always double down on hard 11 against a dealer’s ace, soft 19 (A-8) against dealer’s 6, and A-7 against dealer’s 2.

If you are playing a game where the dealer must hit on soft 17, the above are the three doubling strategy changes you should make vs. the same game where the dealer must stand on soft 17.

Strategy #8: Always double down A-2 through A-7 when the dealer’s upcard is a 5 or 6 In all games, you stand to win more if you always double down an A-2 through A-7 (like: soft 13 through 18) when the dealer’s upcard is a 5 or 6, making it the best strategy. Remember this: The range of dealer’s upcards where you should double down with soft 13 through 18 varies depending upon the number of decks being used and the playing rules. Example: in a double-deck game where the dealer must hit on soft 17, if you were dealt an A-3, you should not only double down when the dealer’s upcard is 5 or 6 but also against a 4. But in all cases when the dealer’s upcard is a 5 or 6, always double down with A-2 through A-7.

Strategy #9: Always stand with a pair of 9s when the dealer’s upcard is 7 Most players know to split a pair of 9s when the dealer’s upcard is 9 or less. Where they fumble the ball is when the dealer shows a 7. In this case, your best strategy is to stand because you’ll win slightly more money than splitting. One way to remember this strategy is as follows: There is a good chance that the dealer will have a ten in the hole since there are four times as many ten-value cards in a deck than other ranks.

Therefore, when the dealer’s upcard is a 7, they often have a pat 17. Your pair of 9s, which is an 18, would beat their potential 17, which makes standing the better play vs. hitting.

Strategy #10: Always surrender hard 16 against a dealer’s 9, 10, or ace upcard and hard 15 against a dealer’s 10 upcard A hard 15 and 16 are two of the worst hands in blackjack, especially when the dealer is showing a strong upcard, like 9, 10, or Ace. You are the underdog but you can minimize your losses by surrendering the above hands against the indicated dealer’s upcards.

Surrender is your best strategy simply because it saves you money in the long run.

Strategy #11: In a single-deck game, always double down on 8 against a dealer’s 5 or 6 upcard In double and multi-deck games, you never double down with a two-card 8. However, in a single-deck game, the odds of blackjack shift to make doubling down the superior strategy over hitting.

Strategy #12: When you are dealt with a pair of 2s or 3s against a dealer’s 2 or 3 upcard, split if the rules allow and hit if they don’t The reason splitting is the better strategy in this case, is because if you split, say, a pair of 2s and draw a 9 giving you an 11, or an 8, giving you a 10, you would be able to bet more money (by doubling down) in a very favorable situation.

Strategy #13: Never make the insurance bet The insurance bet is a sucker bet, which is why your best strategy is to not take insurance when the dealer’s upcard is an Ace. Even when you are dealt a good hand like a 19 or 20, don’t make the insurance bet. The reason is because the payoff for the insurance bet (2 to 1) is less than the odds that the dealer will have a blackjack, making it a sucker bet.

Strategy #14: Stand on hard 16 against a dealer’s 10 upcard if your 16 is multi-card The traditional blackjack basic strategy takes into account only the total of the player’s hand and the dealer’s upcard. With a hard 16 against a dealer’s 10 upcard, the strategy states to hit (assuming surrender is not offered).

Although this strategy is correct, you can improve your playing accuracy by taking into account whether your 16 is a multi-card 16.

Strategy #15: Never play a 6 to 5 Blackjack game Historically, a blackjack hand has always been paid at 3 to 2 odds. For example, if you bet $10 and you have a blackjack, you will be paid $15 in winnings. Nowadays, many casinos pay a winning player’s blackjack at only 6 to 5 odds.

This means that a $10 bet would win you only $12 in a 6 to 5 game. The house edge increases by about 1.45% in a single-deck game with 6 to 5 and moreover, if 6 to 5 is offered in a double or multi-deck game, the house edge escalates to greater than 2%. Your best strategy is to play only blackjack games that offer a 3 to 2 blackjack payoff.
