If you're playing in an offline gambling venue or live dealer blackjack online, then there are certain rules of etiquette you need to follow. While these won't be relevant to most online blackjack players, it's still important to know the right way to act at a blackjack table. There are a few rules in blackjack that can vary slightly from casino to casino. Dealer Hits Soft 17 Generally, the dealer in blackjack must hit if he has a total of 16 or less, and stand if he has 17 or more.
Rules
I overhear a lot of bad gambling advice in the casinos. Perhaps the most frequent is this one, 'The object of blackjack is to get as close to 21 as possible, without going over.' No! The object of blackjack is to beat the dealer. To beat the dealer the player must first not bust (go over 21) and second either outscore the dealer or have the dealer bust. Here are the full rules of the game.
- Blackjack may be played with one to eight decks of 52-card decks.
- Aces may be counted as 1 or 11 points, 2 to 9 according to pip value, and tens and face cards count as ten points.
- The value of a hand is the sum of the point values of the individual cards. Except, a 'blackjack' is the highest hand, consisting of an ace and any 10-point card, and it outranks all other 21-point hands.
- After the players have bet, the dealer will give two cards to each player and two cards to himself. One of the dealer cards is dealt face up. The facedown card is called the 'hole card.'
- If the dealer has an ace showing, he will offer a side bet called 'insurance.' This side wager pays 2 to 1 if the dealer's hole card is any 10-point card. Insurance wagers are optional and may not exceed half the original wager.
- If the dealer has a ten or an ace showing (after offering insurance with an ace showing), then he will peek at his facedown card to see if he has a blackjack. If he does, then he will turn it over immediately.
- If the dealer does have a blackjack, then all wagers (except insurance) will lose, unless the player also has a blackjack, which will result in a push. The dealer will resolve insurance wagers at this time.
- Play begins with the player to the dealer's left. The following are the choices available to the player:
- Stand: Player stands pat with his cards.
- Hit: Player draws another card (and more if he wishes). If this card causes the player's total points to exceed 21 (known as 'breaking' or 'busting') then he loses.
- Double: Player doubles his bet and gets one, and only one, more card.
- Split: If the player has a pair, or any two 10-point cards, then he may double his bet and separate his cards into two individual hands. The dealer will automatically give each card a second card. Then, the player may hit, stand, or double normally. However, when splitting aces, each ace gets only one card. Sometimes doubling after splitting is not allowed. If the player gets a ten and ace after splitting, then it counts as 21 points, not a blackjack. Usually the player may keep re-splitting up to a total of four hands. Sometimes re-splitting aces is not allowed.
- Surrender: The player forfeits half his wager, keeping the other half, and does not play out his hand. This option is only available on the initial two cards, and depending on casino rules, sometimes it is not allowed at all.
- After each player has had his turn, the dealer will turn over his hole card. If the dealer has 16 or less, then he will draw another card. A special situation is when the dealer has an ace and any number of cards totaling six points (known as a 'soft 17'). At some tables, the dealer will also hit a soft 17.
- If the dealer goes over 21 points, then any player who didn't already bust will win.
- If the dealer does not bust, then the higher point total between the player and dealer will win.
- Winning wagers pay even money, except a winning player blackjack usually pays 3 to 2. Some casinos have been short-paying blackjacks, which is a rule strongly in the casino's favor.
Wizard's Simple Strategy
I've been preaching for years that to play blackjack properly requires memorizing the basic strategy. However, after pitching the basic strategy for 20 years, I've learned that few people have the will to memorize it. In my book, Gambling 102, I presented a 'Simple Strategy,' which is seven simple rules to playing blackjack. The cost due to incorrect plays with the Simple Strategy is 0.53%, under liberal Vegas Strip rules.
Ever since my book was published it has bothered me that the cost in errors to my Simple Strategy was too high. So in September 2009 I developed the following 'Wizard's Strategy.' The cost due to imperfect plays is 0.14% only, relative to liberal Vegas Strip rules. That is the cost of one hand for about every 12 hours of play. Compared to the 250 cells in the Basic Strategy, the Wizard's Strategy has only 21, as follows.
Let me be perfectly clear that this strategy is not right 100% of the time. I continue to get Emails saying that when this strategy was used with my practice game, the player was corrected for following it. For example, my simple strategy says to stand on 12 against a 2, when it is mathematically better to hit. If you want to learn a strategy that is correct all the time you should use the appropriate basic strategy for the set of rules you are playing.
Here are some comments of clarification.
- A 'hard' hand is one that either has no aces, or has aces that are forced to count as point, lest the hand bust. A 'soft' hand is one with at least one ace, which may still count as one or eleven points.
- With a hard 10 or 11, double if you have more points than the dealer, treating a dealer ace as 11 points. Specifically, double with 10 against a 2 to 9, and with 11 against 2 to 10.
- If the strategy says to double, but you have three or more cards, or table rules don't allow soft doubling, then hit, except stand with a soft 18.
- If the strategy says to surrender (16 vs. 10), but you can't for whatever reason, then hit.
- If the strategy says to 'not split,' then treat the hand has a hard total of 8, 10, or 20, according to the pair in question.
A reader named Jeff provided another table of my simple strategy, with exceptions in small print. Details about the Wizard's Simple Strategy can be found in my Blackjack appendix 21.

Beware Short Pays on a Blackjack
More and more tables are showing up that pay less than the full 3 to 2 on a blackjack. Most of these tables pay 6 to 5, but some even money and 7 to 5 tables are known to exist. I would estimate that 10% of '21' tables in Las Vegas now pay less than 3 to 2. In my opinion, only games that pay 3 to 2 deserve to be called 'blackjack,' the rest fall under '21' games, including Super Fun 21 and Spanish 21. Regardless of the other rules, you should demand nothing less than 3 to 2 blackjack. You should always check the felt to be sure, and if the felt doesn't say, look for a sign. If nothing says the win on a blackjack, then ask.

Bad Strategies
Three popular bad strategies encountered at the blackjack table are: never bust, mimic the dealer, and always assume the dealer has a ten in the hole. All three are very bad strategies. Following are my specific comments on each of them, including the house edge under Atlantic City rules (dealer stands on soft 17, split up to 4 hands, double after split, double any two cards) of 0.43%.
Never bust: For my analysis of this strategy I assumed the player would never hit a hard 12 or more. All other decisions were according to correct basic strategy. This 'never bust' strategy results in a house edge of 3.91%.
Mimic the dealer: For my analysis of this strategy I assumed the player would always hit 16 or less and stand on17 or more, including a soft 17. The player never doubled or split, since the dealer is not allowed to do so. This 'mimic the dealer' strategy results in a house edge of 5.48%.
Assume a ten in the hole: For this strategy I first figured out the optimal basic strategy under this assumption. If the dealer had an ace up, then I reverted to proper basic strategy, because the dealer would have peeked for blackjack, making a 10 impossible. This 'assume a ten' strategy results in a house edge of 10.03%.

Rules & Strategy
Winning at Blackjack
Like many of our favorite casino games, the exact origins of blackjack are forever lost to history. One of the first recorded descriptions of the game places its appearance in France during the 17th century, where it thrilled gamblers under its simple, yet appropriate appellation “vingt-et-un.” Some gaming historians, however, contend that rather than originating in France, vingt-et-un was nothing more that a variation of Spain’s already popular game “One and Thirty” or perhaps even a spin-off of Italy’s Baccarat.
Regardless of its origins, so popular was the game that it quickly emigrated globally, taking on slight changes in both name and rules to suit regional appetites. In Russia, the game was called “Ochko” (roughly translated as “the hole’). In England, where players were rewarded for drawing both the jack and ace of spades as their first two cards, it became known as “Blackjack.” But whether it’s “21” “California Aces” or even “Ochko” blackjack continues to be one of gambling’s perennial favorites.
Blackjack Basics
In its most basic form, blackjack is one of the easiest casino games to learn. The objective is to attain a hand value that is greater than that of the dealer, yet does not exceed 21. It can be played using anywhere from one to eight standard decks, with cards of rank 2 through 10 scored according to their face value, while face cards—jack, queen, and king—are valued at 10 points. Aces can be worth either 1 or 11 points. The game is further governed by the following rules:
1. Players win if their hand has a greater total point value than the dealers, without going over 21.
2. The best possible hand is called a blackjack and it consists of an ace and any 10-point card. A winning blackjack pays 3:2.
3. If both the player and the dealer have a tie—including with a blackjack—the bet is a tie or “push” and money is neither lost, nor paid.
4. All other winning hands pay even money, 1:1.
5. If either the player or the dealer exceed 21 or “bust” the hand automatically loses.
6. If both the dealer and player bust, the player loses.
A round of blackjack begins with the player placing a bet in the circle or designated betting area in front of him. Every player will then be dealt two cards (both typically face up) while the dealer receives two cards, one of which is exposed and the other (known as the “hole” card) face down. If the dealer has a ten or an ace exposed he will check for blackjack, in which case all player hands lose, except another blackjack. However, should the dealer have an ace exposed, players may take “insurance,” a side-bet that pays 2-1 and hedges the initial bet against a dealer blackjack.
If the dealer does not have blackjack, play continues starting with the player seated immediately to the left of the dealer. The following options are then available:
Stand. If the player decides their hand is sufficiently strong, they may opt to take no additional action.
Hit. Players may draw additional cards until they either bust or decide the stand.
Double down. If a player’s hand warrants, they may opt to double their current bet and receive one additional card. This option is only offered on the first two cards, and in some cases on the first two cards after splitting.
Split. When a player’s first two cards are of equal point value, he may separate them into two hands with each card being the first card of a new hand. To split, the player must make another wager of equal value to the initial wager for the second hand. In cases where another identical point valued card is dealt following the split, re-splitting may be allowed. (Re-splitting aces is often an exception.) When allowed, players may also double down after splitting.
Surrender. In certain versions of blackjack, players may surrender or yield a poor hand on their first two cards, rather than play against a potentially superior hand. Surrendered hands return ½ of the wager to the player.
Once all players have acted, the dealer will then complete his hand. Unlike players, the dealer has no freedom to determine the best course of play and must abide by the house rules which govern all actions. Usually the dealer must hit until his cards reach a total value of 17 or more. In some casinos or game versions, if a dealer is dealt a soft 17 (an ace plus cards totaling six additional points) he must also hit. If the dealer busts all players active in the hand win automatically.
Basic Strategy
Despite its simplistic premise, blackjack is one of the most difficult games in the casino. But with an extremely low vigorish—sometimes reaching 0.18%–it can also be one of the most profitable. Or at least it is if you master basic strategy.
Although daunting and at times confusing, basic strategy it is really nothing more than a breakdown of the optimal way to play every possible situation based on the house’s rules, your current hand and the dealer’s exposed card. Below is a sample basic strategy table for use with multiple deck games.
Key: H=Hit
S=Stand
D=Double if allowed; If not, hit.
Key: H=Hit
S=Stand
D=Double if allowed; If not, hit.
D/S=Double if allowed; If not, stand
Key: SP=Split the pair.
N=Don’t split.
Remember, optimal basic strategy varies with the version of the game that you play, and there are tables such as these that outline exactly what action to take given the circumstance. And while they may be challenging to memorize, if making money as a blackjack player is you’re ultimate goal, there’s simply no other option.
Quick Tips: Strategies to avoid
A lot of new players can be taken in by seemingly sound strategies that actually have no real place at the tables. Avoid the following dangerously ineffective methods.
1. Play as the dealer plays. Some people think that because the house has an edge on the game that by playing according to the dealer’s rules (such as always hitting 16 or less, or never doubling or splitting) that same edge will apply. Wrong. Remember, it’s the player who acts first and even if both you and the dealer bust, the house wins the hand. Such strategy results in a house edge of approximately 5.5%
2. Martingale System. Some players advocate an age-old, misguided betting system design ostensibly to guarantee winning. Called the “Martingale System,” this method requires players to double their bet for every hand following a loss. The theory is that by doubling the bet you will eventually win a hand and recoup any previous losses. Although it sounds powerful, this system is flawed and ineffective, and fails to take into account high-risk bets, a moderately bad run of cards, and table limits.
3. Never draw to a hand that can bust. Rather than take a card that could break the hand, some players prefer to always stand pat on hard totals of 12 or more. Such play is harmful in the long run and results in a vigorish of approximately 4%.
Although these and many other half-baked strategies may sound good in theory, at best they’re mildly innocuous and worst devastating. Steer clear of tricks and systems and stick with basic strategy, the only proven method of minimizing the house’s edge.
