Blackjack Basic Strategy: The Only Chart You Need

If you play blackjack with no plan, the house keeps 1–2% more of your bankroll than it should. That is a quiet leak. A simple, proven chart can fix most of it. In this guide you will see one chart that works for the most common games, how to read it fast, and what small rule changes do to your choices. If you want a short background on the game itself, here is a clear blackjack overview on Britannica. Save this page. Practice with it. You will feel the game slow down and make sense.

The 60-Second Takeaway

Basic strategy is a map. It tells you the best move for each player total vs the dealer upcard, assuming normal shoe games. It does not beat the house. It cuts the edge down to a small number. That is your job as a smart player.

• Hard vs soft: hard hands have no ace counted as 11; soft hands have an ace counted as 11 and can fall back to 1.
• Pairs are special: sometimes you split to turn one bad hand into two good hands.
• Double when the math is strong. You push more money when you are a favorite.
• Surrender late if allowed. Give up weak 15–16 vs big dealer cards to lose less now and more often win later.
• 16 vs dealer 10 feels bad either way. With late surrender, fold it. No surrender? Hit it.
• Do not split 10s. Ever. That “big move” burns money.
• Rules matter. H17 vs S17, DAS vs NDAS, and surrender on/off shift a few squares on the chart.

If you read only this: learn to spot soft 18 (A,7), hard 12, 16 vs 10, 11 vs dealer ace, and pairs of 8s. Those five shapes win or lose you the most over time.

The Chart (Built for Real Tables)

This chart is tuned for common shoe games: 6–8 decks, dealer hits soft 17 (H17), double after split (DAS), late surrender. It uses short codes: S = Stand, H = Hit, D = Double (if not allowed, Hit), Ds = Double if allowed else Stand, P = Split, R = Surrender (if not allowed, use the fallback shown). Small rule tweaks can change a few cells. See the notes under the tables and the “Rule Tweaks” section.

Legend

S = Stand, H = Hit, D = Double (else Hit), Ds = Double (else Stand), P = Split, R = Late Surrender (else follow listed fallback)

Hard Totals

Soft Totals (Ace counted as 11)

Pairs

Note on surrender in this chart: surrender hard 16 vs 9, 10, or A; surrender hard 15 vs 10. If surrender is not offered, follow the fallback in brackets or the normal Hit/Stand rule for that total.

How To Read The Chart Without Second-Guessing Yourself

Here is the fast method I use at the table.

1. Classify your hand. Is it hard, soft, or a pair? If you have an ace and it can still count as 11 without busting, it is soft. Two of the same rank is a pair.
2. Find the dealer upcard on the top row.
3. Scan to your row. Do the move in the cell. If the cell says D but the table does not allow it, use the fallback (Hit or Stand as marked).
4. Apply the table rules. Our main chart is for 6–8 decks, H17, DAS, late surrender. If your table says S17 or no surrender or NDAS, a few cells change. See the next section for those shifts.

If the idea of “best move” feels abstract, a short math refresh helps. Try this quick quick refresher on expected value. In blackjack, each move has an EV vs each upcard. The chart picks the highest EV every time.

Micro-drill (three hands): 1) You hold A,7 vs dealer 6. That is soft 18. The chart says Ds. Double if you can. If not, Stand. 2) You hold 9,7 vs dealer 10. Hard 16 vs 10. With late surrender, R. If not, Hit. 3) You hold 9,9 vs dealer 7. Do not split. Stand. This one saves a lot over time.

The Rule Tweaks That Break Your Muscle Memory

Small rule notes can flip a few choices. Know your table. If the felt says “S17,” the dealer stands on soft 17. If it says “H17,” the dealer hits soft 17. DAS means you can double after a split. NDAS means you cannot. Some rooms offer late surrender (you can fold after the dealer checks for blackjack). Deck count also matters a bit.

• H17 vs S17: In H17 games, the dealer draws one more card on A,6. That helps the house a little. It also pushes some doubles more often, like 11 vs A (D in H17; often Hit in S17).
• DAS vs NDAS: With DAS, you can split and still double on the new hand. That makes splits like 2,2 / 3,3 vs dealer 2–3 better. In NDAS, you split those a bit less.
• Surrender on/off: With late surrender, you fold 16 vs 9/10/A and 15 vs 10. No surrender? Then you Hit those.
• Decks: Single- and double-deck improve your results a little and tweak a few edges. Some doubles change (for example, soft 18 vs 2 can turn into a double in some single-deck sets).

The Misplays You’re Probably Making (And How To Fix Them)

Most leaks come from a short list. Fix these and you are already ahead of most players at your table.

• Standing on 12 vs 2 or 3. You should Hit. Standing here is a slow bleed.
• Hitting 12 vs 4–6. You should Stand. Let the dealer break.
• Not doubling A,7 vs 3–6. Soft 18 is a great double vs 3–6.
• Splitting 10s. Keep the 20. It wins a lot.
• Not surrendering 16 vs 9/10/A when you can. It saves money in the long run.
• Standing on 16 vs 10 without surrender. You should Hit. Yes, it feels bad. But it loses less over time.
• Splitting 4,4 vs 5–6 only when DAS is allowed. If NDAS, do not split; just Hit.

A Short, Honest History Of “The Chart”

The chart grew from math, not hunch. In the 1960s, Edward O. Thorp ran early computer sims and wrote a slim book that shook casinos. You can still get it: Edward O. Thorp’s Beat the Dealer. Later, better sims refined the edges for each rule set. Today, the basic chart you see here is the result of billions of hand sims.

Card counting came next. That is not part of basic strategy. It sits on top of it. Famous groups like the MIT Blackjack Team used both. Here is a simple read on that story: the MIT Blackjack Team history. You do not need to count to gain from the chart. The chart alone lowers the house edge sharply.

Small personal note: the first time I used late surrender on 16 vs 10, I felt odd, like I “quit.” Then I tracked results over a month. The red line on my log was thinner. The math worked, feelings aside.

Practice Plan: From Chart To Table

Turn the chart into habit. Ten minutes a day is enough.

1. Flash rounds: Take a deck at home. Deal two cards to yourself and one upcard for the dealer. Say your move out loud in two seconds. Check the chart. Move on. Aim for 100 hands in 10 minutes.
2. Low-stakes or demo play: Use a site that shows table rules clearly (H17/S17, DAS, surrender, decks). If you want a quick filter and plain-language notes on real tables, see our independent picks and guides. If you enjoy other table games too, our roulette page is kept current: Rulett online kaszinó 2026 (Hungarian guide, updated each year).
3. Live tune-up: When you sit down, check the placard for rules. If they differ from the main chart, recheck the “Rule Tweaks” above. Keep a tiny printout in your wallet. Most rooms allow it if you do not slow the game.

Quick Test: Can You Beat These Five Hands?

Try to answer in two seconds each. Answers right below.

1. You: 10,6 vs dealer 10 (no surrender). What now?
2. You: A,7 vs dealer 3.
3. You: 9,9 vs dealer 9.
4. You: 11 vs dealer A (H17).
5. You: 8,8 vs dealer A (late surrender offered).

Answers: 1) Hit (16 vs 10, no surrender). 2) Double (soft 18 vs 3). 3) Split (9,9 vs 9). 4) Double (11 vs A in H17). 5) Split (always split 8s; surrender is not the best here).

FAQ

What is the house edge if I follow basic strategy?

In common shoe games with H17 and DAS, the house edge drops to about 0.5–0.8%. With S17 and the same good rules, it can go near 0.3–0.5%. See the math here: verified house edge estimates.

Do I need different charts for single-deck vs six-deck blackjack?

The core stays the same. A few doubles and splits change (for example, some single-deck sets double soft 18 vs 2). If you move between games, keep a small note for those rule flips. The chart above is for 6–8 decks, H17, DAS, late surrender.

Is card counting the same as basic strategy?

No. Basic strategy is the right move for each total vs each upcard under set rules. Counting is a way to track the shoe and shift bets and a few plays when the count is high. You always use basic strategy as your base, even if you count.

When should I deviate from the chart?

Only when the table rules are different from the chart’s rules (H17 vs S17, DAS vs NDAS, surrender on/off, deck count). Or if you are using an advanced, tested deviation based on a running count. If not, stick to the chart. It beats guesswork.

Can basic strategy overcome the house edge?

No. It only reduces the edge to a small number. That is still an edge. If you play, set limits, take breaks, and treat it as paid fun, not income. For support or tips on limits, see the NCPG link above. If you are in the UK, see BeGambleAware’s advice on staying in control.

Final Notes

Print the chart. Put it in your wallet or save a screenshot. Drill 10 minutes a day. Track hands that confuse you and fix them next time. If you need a place to practice with clear rules and low stakes, scroll back to the practice section and pick a safe option that fits your laws. Play within your limits, and let the math do quiet, steady work for you.
