Start With the Table Limits and the Buy-In
Before you sit down, look at the placard on the table. It states the minimum and maximum wager for that specific table, along with the rule variants in use. The buy-in is the moment you convert cash into chips. Place your money on the felt rather than handing it to the dealer, who will spread it, count it, and push the equivalent chips toward you. You do not touch the chips during the count, and you do not hand cash directly to the dealer in most venues because the surveillance camera needs a clear view of the transaction.
Once you have chips, place your wager in the betting circle printed in front of your seat before the dealer begins the round. The dealer then deals from a shoe, which holds multiple decks, or from a pitch game dealt by hand. The number of decks is one of the rule variants that changes the underlying mathematics of the game.
The Objective and the Order of a Hand
The objective is a hand total closer to 21 than the dealer's without exceeding 21. You play against the dealer only, not against the other players at the table. Each card counts its face value, face cards count as ten, and an ace counts as either one or eleven, whichever helps the hand more at that moment.
A round follows a fixed sequence. You place a bet, and the dealer gives every player two cards face up. In most shoe games the dealer takes one card face up and one face down; in some variants the dealer takes only one card until the players finish. If the dealer's face-up card is an ace, the dealer offers insurance before play continues. Insurance is a side bet that the dealer's hole card is a ten-value card, and it is a separate wager with its own house edge.
If your first two cards total 21, you have a blackjack and are normally paid at 3 to 2 on your wager, unless the table rules state a different payout such as 6 to 5. If the dealer also has a blackjack, the hand pushes and your bet is returned. If you do not have a blackjack, you play your hand through the decision points below, and then the dealer reveals the hole card and plays according to a fixed rule printed on the table, usually drawing to 16 and standing on 17, with a distinction between a soft 17, which contains an ace counted as eleven, and a hard 17.
What Each Decision Means
When the dealer points to you, the available decisions depend on your two cards and the dealer's upcard. The most common decisions are:
- Hit: take another card. You may hit as many times as you like until you stand or your total exceeds 21, at which point the hand is a bust and your wager is collected.
- Stand: keep your current total and end your turn.
- Double down: place an additional wager equal to your original bet and receive exactly one more card. The hand then stands automatically.
- Split: if your first two cards have the same value, you may separate them into two hands, each with its own wager equal to the original. You then play each hand independently. Some tables allow re-splitting, and some allow doubling after a split.
- Surrender: on tables that offer it, you may forfeit half your wager and end the hand before taking any further cards. Late surrender occurs after the dealer checks for blackjack; early surrender, which is rare, occurs before that check.
Each decision changes the expected rate of loss on the hand. The correct choice for any given combination of your total and the dealer's upcard is not a matter of intuition; it is derived from the specific rule set in use. Published basic-strategy charts are tables of those decisions, and a chart produced for one rule set is not necessarily correct for another. The deck count, whether the dealer stands or hits on soft 17, whether doubling after splitting is allowed, and the surrender option all shift the correct play on certain hands.
How the Main Rule Variants Compare
The placard on the table is the authoritative statement of which rules apply. The following table shows the practical effect of the common variants, without attaching a percentage figure to any single one because the figures depend on the other rules in force at the same table.
| Rule variant | What it changes | What to check before you sit down |
|---|---|---|
| Dealer hits soft 17 | The dealer takes another card when holding an ace counted as eleven and a total of 17 | Printed on the table layout as "Dealer hits soft 17" or "Dealer stands on all 17s" |
| Blackjack pays 6 to 5 instead of 3 to 2 | A blackjack returns less on the same wager | Printed near the table minimum or on the felt |
| Double after split allowed or not | Whether a split hand may be doubled, which changes the correct strategy on some split pairs | Ask the dealer or read the table rules |
| Late surrender offered or not | Whether you may forfeit half the bet on a weak starting hand | Ask the dealer; rarely printed |
| Number of decks in the shoe | Changes the composition of remaining cards and therefore the correct basic strategy on marginal hands | Visible on the shoe or stated by the dealer |
Hard Hands, Soft Hands, and the Dealer's Upcard
A hard hand is any hand without an ace, or a hand where the ace must be counted as one to avoid busting. A soft hand contains an ace counted as eleven. The distinction matters because a soft hand cannot bust on a single hit: if the new card would push the total over 21, the ace simply becomes worth one. That extra flexibility changes the correct play on hands like soft 17 or soft 18, where standing may be correct against one dealer upcard and hitting against another.
The dealer's upcard drives most basic-strategy decisions because the dealer's play is constrained by a fixed rule. When the dealer shows a low card, the dealer is more likely to bust, and the correct play often favours standing on lower totals. When the dealer shows a strong card, you must take more risk to have a chance of winning the hand. None of this changes the house edge on the game as a whole, which remains with the operator on every wager; it changes the expected loss on individual decisions within the hand.
Procedural Mistakes That Cost New Players
The first mistake is touching the cards in a shoe game. In games dealt from a shoe, players never touch the cards at all. In pitch games, where the cards are dealt face down, you may pick them up, but you must hold them above the table and use only one hand. The second mistake is handling chips after the round has begun. Once the dealer starts dealing, you cannot add to or remove from your wager except when the rules permit a double down or a split, and those additional chips are placed beside the original bet, never on top of it.
A third mistake is taking insurance as a habit. Insurance is a side bet on the dealer's hole card, and it carries its own house edge that is separate from the main bet. Over many hands, taking insurance on every dealer ace increases the expected rate of loss. The decision to take insurance is a strategy decision like any other, and the published charts for the rule set in use will state when, if ever, it is correct.
Where the Strategy Charts Come From
A basic-strategy chart is a complete list of the correct play for every combination of your hand and the dealer's upcard under one specific rule set. The chart is computed by evaluating every possible continuation of the hand and choosing the play that minimises expected loss. It is not a system for beating the game, and it does not promise a profit. It removes the avoidable mistakes that come from guessing, and it leaves the built-in house edge as the only remaining factor on each wager.
Because the chart depends on the rules, the first thing to do when you sit down is to read the placard and adjust the chart you are using. A chart for a six-deck shoe where the dealer stands on all 17s will differ on a few hands from a chart for a double-deck pitch game where the dealer hits soft 17. The differences are small in number but material in effect, and they are exactly the kind of detail that a printed chart exists to resolve.
FAQ
Can I learn blackjack without memorising a strategy chart?
You can play without a chart, but every decision you make by feel will carry a higher expected loss than the decision the chart specifies for that rule set. A printed chart is allowed at most tables, and many players keep one beside them while they learn. The chart is a reference, not a guarantee, and it does not change the fact that the house holds an edge on every wager.
What does it mean when the dealer has a soft 17?
A soft 17 is a hand containing an ace counted as eleven plus cards totalling six, such as ace-six. Because the ace can also count as one, the hand totals either 7 or 17. The table rules state whether the dealer must hit or stand on that total, and the answer changes the correct play for the player on several starting hands.
Why do some blackjack tables pay 6 to 5 instead of 3 to 2?
The payout on a blackjack is a rule set by the operator, printed on the table. A 6 to 5 payout returns less money on the same wager than a 3 to 2 payout, which changes the expected loss on the game as a whole. The payout is always visible on the felt or the table placard before you place a bet, and it is one of the first things to check when you choose a table.
