What is Blackjack Basic Strategy and Why Does It Work?
Blackjack basic strategy is a complete set of optimal decisions for the player, calculated by computers that have simulated millions of hands. For every possible combination of your hand and the dealer’s visible card, there is one play—Hit, Stand, Double Down, Split, or Surrender—that has the highest Expected Value (EV). This means that over the long term, making that specific move will result in the highest average return.
It’s important to understand that basic strategy does not guarantee a win on every single hand. You can make the perfect move and still lose. However, by consistently applying the correct strategy, you are minimizing your losses and maximizing your wins over time. Think of it as a mathematically perfect “cheat sheet” that is completely legal to use at any online or land-based casino. Its effectiveness is backed by decades of analysis from authorities like the “Wizard of Odds” and illustrated by groups like the famous MIT Blackjack Team.

6-8 Deck Blackjack Strategy Chart: Dealer Stands on Soft 17 (S17)
This is the most common and player-friendly set of rules you’ll find in most casinos. If you’re going to memorize one chart, make it this one.
6-8 Deck Blackjack Strategy Chart: Dealer Hits on Soft 17 (H17)
Many casinos use the H17 rule, which slightly increases the house edge. This chart adjusts for that rule, requiring slightly more aggressive plays in certain situations, like doubling down on 11 versus a dealer’s Ace.

Double Deck Blackjack Strategy Chart
Fewer decks slightly favor the player, which results in minor strategic changes compared to a 6-deck game. If you find a double-deck game, be sure to use the correct chart.

How to Read a Blackjack Basic Strategy Chart in 3 Simple Steps
At first glance, the chart might look intimidating, but using it is incredibly simple. Just follow these steps:
- Find Your Hand: Look down the vertical column on the far left of the chart. Find the row that matches your current hand’s total (e.g., “Hard 12,” “Soft 18,” or “Pair of 8s”).
- Find the Dealer’s Upcard: Look across the horizontal row at the very top of the chart. Find the column that corresponds to the dealer’s visible card (e.g., “2,” “7,” or “Ace”).
- Find the Action: The box where your hand’s row and the dealer’s card’s column intersect contains the correct play. This is the mathematically optimal move.
Chart Legend:
- H = Hit
- S = Stand
- D = Double Down (if not allowed, Hit)
- P = Split
- Sr = Surrender (if not allowed, Hit)
Let’s use a classic scenario: You have a Hard 12 and the Dealer shows a 2. A common mistake is to stand, fearing you’ll bust. But if you look at the chart, it clearly tells you to HIT. Why? Because the mathematical odds show you’re more likely to improve your hand without busting than you are to win by standing, especially given the dealer’s weak starting card.
Key Game Rules That Change Your Strategy
The reason there isn’t just one universal chart is that small changes in the game rules can alter the optimal play. Here are the key rules to look for:
- S17 vs. H17 (Soft 17 Rule): A soft 17 is a hand with an Ace that counts as 11 (e.g., Ace-6). An “S17” rule means the dealer must Stand on this total, which is better for the player. An “H17” rule means the dealer must Hit, giving them another chance to improve their hand and increasing the house edge.
- Number of Decks: Fewer decks mean a slightly lower house edge and minor changes to strategy, particularly with doubling and splitting decisions.
- Blackjack Payouts (3:2 vs. 6:5): This is critical. ALWAYS play at tables where a natural blackjack pays 3:2. A 6:5 payout dramatically increases the house edge by ~1.39%, making the game significantly worse for the player, even with perfect strategy.
- Surrender: Late Surrender allows you to forfeit half your bet after seeing the dealer’s upcard. It is a favorable player option when used correctly (e.g., surrendering a Hard 16 against a dealer’s 10).
Odds and Payouts: The Math Behind the Chart
Using basic strategy directly impacts the house edge and your long-term odds. This table shows just how much of a difference your decisions make.
| Scenario | House Edge (Approx.) | Player Impact |
|---|---|---|
| Typical Player (No Strategy) | 2.0% or higher | Very High |
| Perfect Basic Strategy (S17, 6 Decks) | 0.4% – 0.5% | Optimal |
| Perfect Strategy (H17, 6 Decks) | 0.6% – 0.7% | Slightly Worse |
| Playing a 6:5 Payout Game | Adds ~1.39% | Extremely Bad |
5 Common Mistakes Basic Strategy Helps You Avoid
Playing with basic strategy instantly eliminates costly errors that most amateur players make. Here are five of the most common:
- Taking Insurance: The chart never recommends taking Insurance. It is a side bet on the dealer having a blackjack, and it carries a high house edge. It’s a losing bet in the long run.
- Never Splitting Aces & 8s: The chart will always tell you to split a pair of Aces and a pair of 8s. Two Aces give you two chances at 21, and a pair of 8s (a Hard 16) is the worst possible hand to start with, so splitting it is always the best option.
- Standing on Soft 18 vs. a Dealer 9, 10, or Ace: It feels safe to stand on 18, but against a strong dealer card, basic strategy correctly tells you to HIT. You have a chance to improve your hand with no risk of busting.
- The “Dealer’s Bust” Fallacy: Many players are afraid to hit a 12-16 against a dealer’s 2-6 because they fear busting. The chart tells you to stand in many of these spots, but not all. Trust the math—the dealer’s bust potential is already factored in.
- Emotional Plays: Abandoning the chart after losing a few hands in a row. The most critical mistake is not being consistent. Basic strategy works over thousands of hands, not just the next one.

Frequently Asked Questions (FAQ)
What is the perfect basic strategy for blackjack?
The “perfect” strategy is the one that perfectly matches the exact rules of the table you’re playing at. This includes the number of decks, the dealer’s soft 17 rule (S17/H17), and rules on doubling down and splitting. There is no single universal chart that is perfect for every game.
Do you hit a 12 against a 2?
Yes. According to every standard basic strategy chart, the correct move is to HIT your Hard 12 against a dealer’s 2. While it feels risky, mathematically it gives you the best chance to win or push in the long run compared to standing.
What is the best blackjack strategy chart?
The best chart is the one that corresponds to your game’s rules. However, for most players, the 6-Deck S17 chart is the most valuable one to learn first, as it covers the most common and favorable game type found in online and land-based casinos.
What is the soft 17 rule in blackjack?
A soft 17 is any hand totaling 17 that includes an Ace counted as 11 (for example, an Ace and a 6). The casino’s rule dictates whether the dealer must “Stand” on this total (S17) or “Hit” it (H17). The S17 rule is always better for the player.
Is using a blackjack strategy chart considered cheating?
No, it is not cheating. It is perfectly legal. In land-based casinos, you are allowed to bring a small, printed strategy card with you to the table. Online, it’s even easier to use. You are simply using mathematical information to play smarter, not altering the outcome of the game.
Is basic strategy the same as card counting?
No. They are two different concepts. Basic strategy is a fixed set of rules for playing your hand against the dealer’s upcard. Card counting is an advanced technique used to track the ratio of high-to-low cards left in the shoe to determine when the player has a statistical advantage and should bet more.
Remember to always gamble responsibly. Set limits for yourself, never bet more than you can afford to lose, and ensure you are playing for entertainment. If you feel you may have a gambling problem, please seek help from a professional organization.
