In a multi-hand, face-up, single deck game, it is possible to establish whether insurance is a good bet simply by observing the other cards on the table after the deal; even if there are just 2 player hands exposed, and neither of their two initial cards is a ten, then 16 in 47 of the remaining cards are tens, which is larger than 1 in 3, so insurance is a good bet.

The Natural or Blackjack hand is where the game gets its name. These hands occur when the first two cards a player is dealt or dealer are Ace and a face card, which equals On average, this lucky hand will occur around every 20 hands. Getting this hand guarantees that the player will win the hand in addition to a 3: In the first round of the game, splitting pairs can occur if a player has two cards that are of the same value. If this happens, the player has the option to separate the cards into two different hands and play them individually.
The second hand is required to have another bet, and depending on the casino, a player will be allowed multiple resplits up to 3 or 4 if he continuous to draw the same value card. The limitations of this rule apply to two Aces, for which a player can only draw one card for each instead of two when splitting.
Doubling down is a double bet on your first two cards. When you use this rule, however, you are only allowed to draw one more card per bet.
It is suggested that this hand be used when you have a hand that cannot be busted or the dealer is holding a hand that could easily lead to a bust. Not very many casinos allow for this rule.

Also when playing basic strategy never take insurance or "even money. Estimates of the house edge for blackjack games quoted by casinos and gaming regulators are generally based on the assumption that the players follow basic strategy and do not systematically change their bet size. Most blackjack games have a house edge of between 0. Casino promotions such as complimentary matchplay vouchers or 2: Basic strategy is based upon a player's point total and the dealer's visible card.
Players may be able to improve on this decision by considering the precise composition of their hand, not just the point total. For example, players should ordinarily stand when holding 12 against a dealer 4. However, in a single deck game, players should hit if their 12 consists of a 10 and a 2. The presence of a 10 in the player's hand has two consequences: However, even when basic and composition-dependent strategy lead to different actions, the difference in expected reward is small, and it becomes even smaller with more decks.
Using a composition-dependent strategy rather than basic strategy in a single deck game reduces the house edge by 4 in 10,, which falls to 3 in , for a six-deck game. Blackjack has been a high-profile target for advantage players since the s. Advantage play is the attempt to win more using skills such as memory, computation, and observation.
These techniques, while generally legal, can be powerful enough to give the player a long-term edge in the game, making them an undesirable customer for the casino and potentially leading to ejection or blacklisting if they are detected. The main techniques of advantage play in blackjack are as follows:. During the course of a blackjack shoe, the dealer exposes the dealt cards.
Careful accounting of the exposed cards allows a player to make inferences about the cards which remain to be dealt. These inferences can be used in the following ways:.
A card counting system assigns a point score to each rank of card e. When a card is exposed, a counter adds the score of that card to a running total, the 'count'. A card counter uses this count to make betting and playing decisions according to a table which they have learned. The count starts at 0 for a freshly shuffled deck for "balanced" counting systems. Unbalanced counts are often started at a value which depends on the number of decks used in the game. Blackjack's house edge is usually between 0.
Card counting is most rewarding near the end of a complete shoe when as few as possible cards remain. Single-deck games are therefore particularly susceptible to card counting. As a result, casinos are more likely to insist that players do not reveal their cards to one another in single-deck games.
In games with more decks of cards, casinos limit penetration by ending the shoe and reshuffling when one or more decks remain undealt. Casinos also sometimes use a shuffling machine to reintroduce the exhausted cards every time a deck has been played.
Card counting is legal and is not considered cheating as long as the counter isn't using an external device, : Sometimes a casino might ban a card counter from the property.
The use of external devices to help counting cards is illegal in all US states that license blackjack card games. Techniques other than card counting can swing the advantage of casino blackjack toward the player. All such techniques are based on the value of the cards to the player and the casino as originally conceived by Edward O. Shuffle tracking requires excellent eyesight and powers of visual estimation but is more difficult to detect since the player's actions are largely unrelated to the composition of the cards in the shoe.
Arnold Snyder's articles in Blackjack Forum magazine brought shuffle tracking to the general public. His book, The Shuffle Tracker's Cookbook, mathematically analyzed the player edge available from shuffle tracking based on the actual size of the tracked slug. Patterson also developed and published a shuffle-tracking method for tracking favorable clumps of cards and cutting them into play and tracking unfavorable clumps of cards and cutting them out of play. The player can also gain an advantage by identifying cards from distinctive wear markings on their backs, or by hole carding observing during the dealing process the front of a card dealt face down.
These methods are generally legal although their status in particular jurisdictions may vary. Many blackjack tables offer a side bet on various outcomes including: The side wager is typically placed in a designated area next to the box for the main wager. A player wishing to wager on a side bet is usually required to place a wager on blackjack. Some games require that the blackjack wager should equal or exceed any side bet wager.
A non-controlling player of a blackjack hand is usually permitted to place a side bet regardless of whether the controlling player does so. The house edge for side bets is generally far higher than for the blackjack game itself. Nonetheless side bets can be susceptible to card counting. A side count, designed specifically for a particular side bet, can improve the player edge.
Only a few side bets, like "Lucky Ladies", offer a sufficient win rate to justify the effort of advantage play. In team play it is common for team members to be dedicated toward counting only a sidebet using a specialized count. Blackjack can be played in tournament form. Players start with an equal numbers of chips; the goal is to finish among the top chip-holders. Depending on the number of competitors, tournaments may be held over several rounds, with one or two players qualifying from each table after a set number of deals to meet the qualifiers from the other tables in the next round.
Another tournament format, Elimination Blackjack , drops the lowest-stacked player from the table at pre-determined points in the tournament. Good strategy for blackjack tournaments can differ from non-tournament strategy because of the added dimension of choosing the amount to be wagered. As in poker tournaments, players pay the casino an initial entry fee to participate in a tournament, and re-buys are sometimes permitted.
Some casinos, as well as general betting outlets, provide blackjack among a selection of casino-style games at electronic consoles. Video blackjack game rules are generally more favorable to the house; e. Video and online blackjack games deal each coup from a fresh shoe, rendering card counting much less effective.
