Blackjack Basic Strategy: A Beginner’s Cheat Sheet

Version: v1.1 — S17, 6-deck, DAS, late surrender | Last updated: Feb 2026

Seat open at a $10 table. Chips click. The dealer flips a 10. You have a hard 16. Your hands sweat. A few players say, “Stand and hope.” One says, “Hit, you have to.” You feel stuck. This is the moment when a simple, tested plan beats a gut call.

Blackjack is not about hunches. It is about math that cuts the house edge. With the right moves, you can lower the edge close to 0.5% in many games. That is why pros use a basic chart. It tells you when to hit, stand, double, split, or surrender for each hand and each dealer upcard. This guide gives you a clear cheat sheet, and shows how to use it fast at the table. If you want proof the numbers are real, see the math on house edge here: house edge in blackjack.

What you will get (and how to use it in seconds)

You will get one table for common rules, five quick rules to start, short drills to learn, and notes for strange tables. You can save or print the chart and take it to a live game (where allowed). Use this if you want a clear answer at the table, not a long math talk.

The only three things to memorize first

Before you learn all cells on a chart, lock these three ideas. They will fix most leaks on day one.

1. Soft hands are not “made.” A soft 18 (A,7) is not always a stand. Versus 3–6 you should double. Versus 9, 10, A you should hit. Treat soft totals as hands you can grow.
2. Split right, not often. Always split A,A and 8,8. Never split 10,10. For 9,9, split vs 2–6 and 8–9, but stand vs 7, 10, A. Correct splits save more money than “lucky” hits.
3. Use surrender when it hurts most. With late surrender, fold hard 16 vs 9, 10, or A, and 15 vs 10. That small loss now beats a big loss later.

These three cover many tough spots. Next comes the full chart. Keep the legend in mind and you will be fine.

The cheat sheet chart

This chart is for common shoe rules: 6 decks, dealer stands on soft 17 (S17), double after split (DAS) allowed, late surrender (LS) allowed, dealer peek for blackjack. If your table uses H17 (dealer hits soft 17), or no surrender, see the notes below and the Exceptions section. For a classic reference, compare with this blackjack basic strategy chart.

Legend

• H = Hit
• S = Stand
• D = Double (if not allowed, Hit)
• Ds = Double if allowed, else Stand
• P = Split
• Ph = Split if DAS, else Hit
• R = Surrender (if not allowed, Hit)

Accessibility: Letters are spelled out in each cell. Caption states the rules. Screen readers: table headers use scope for rows and columns.

Quick examples: Hard 16 vs 10 = R (surrender). If no surrender, Hit. Soft 18 vs 4 = D. Pair 10,10 vs 6 = Stand (do not split).

If your game is H17: changes are small. Key ones: 11 vs Ace becomes Double (not Hit). A,8 vs 6 becomes Ds (Double if allowed, else Stand). See Exceptions below.

Why this works (the math in plain words)

Every choice has an expected value (EV). EV is the average result if you could play the same spot a huge number of times. A choice with a higher EV is the right move. If you want a fast intro, this is a clear lesson on expected value explained.

Why stand on 13 vs 6? The dealer will bust more often from a 6. Your bust risk is high if you hit. Stand keeps your hand safe and lets the dealer break. Why hit 12 vs 2? The dealer’s 2 is not as weak. If you stand on 12, you lose too often. A small bust risk now is better than many later losses. The ideas come from many computer runs. For a deeper dive, see this piece on the math behind blackjack.

Soft hands act like “free hits.” An Ace lets you take one more card without going over 21. So the chart pushes soft hands harder. You double soft 18 vs 3–6 because many cards help you and the dealer is weak.

Exceptions that change the chart

Rules are not the same at all tables. In some places the dealer hits soft 17 (H17). Some shoes do not allow surrender. Some allow double after split; some do not. Some have no “peek” for blackjack. Casinos and laws set these rules. You can see how blackjack rules vary by jurisdiction.

• H17 vs S17: In H17, the dealer makes more hands. You should be a bit more aggressive. Key flips: Double 11 vs Ace (H17), A,8 vs 6 becomes Ds (if allowed). A few soft doubles add or shift.
• No surrender: Replace all R with Hit. This hurts most on 16 vs 9/10/A and 15 vs 10. Plan your bankroll.
• No DAS: Cells marked Ph become Hit, not Split. This lowers the value of splitting 4,4 and 6,6 in a few spots.
• Deck count: Fewer decks shift a few close calls. But most cells stay the same for 2–8 decks with S17.
• Payouts: 3:2 blackjack is standard. 6:5 hurts your return a lot. Try to avoid 6:5.

If you want a simple view of why these rules change the edge, read the regulator guide to Return to Player and house edge. The gist: rules shift the long-run payback by small, steady steps.

Common beginner mistakes you can stop today

• Standing on soft 18 vs 3–6. It feels safe. But double wins more in the long run.
• Splitting 10s “for action.” Do not split 10,10. You already have a strong hand.
• Hitting 12 vs 6. Stand. Let the dealer bust.
• Skipping a double on 10 vs 9. It feels scary, but double is right.
• Forgetting surrender exists. Use it on 16 vs 9/10/A and 15 vs 10.
• Chasing losses with big bets. This is not strategy. Set limits first.

10-minute drills to learn the chart

Drill 1: Hard hands only. Take a deck. Deal yourself two cards and set a dealer upcard. Say the move out loud. Check the chart. Aim for 50 hands in 10 minutes. Do this for hard 5–17 until you can answer in two seconds.

Drill 2: Add soft hands. Focus on A,2 to A,7. Say the rule, not just the letter. Example: “A,7 vs 4 — Double.” Then add pairs for day three. If you like a web tool, try this free blackjack strategy trainer. It flags errors and tracks speed.

Card counting is not basic strategy. Counting changes bets and a few plays when the shoe is rich in tens and Aces. If you want to see the difference, here is a clear intro on how card counting differs from basic strategy.

Where to practice safely (and how to vet games)

Practice free first. Use demo games and trainers. If you try an online game, look for clear rules (S17 vs H17, DAS, surrender). Check that the game uses fair RNG and that a third party tests it. You can read about independent testing of RNG by labs like eCOGRA.

Before you risk money, read neutral reviews that list rules, licenses, and payout speed. I like to see license numbers, game providers, and table rules at a glance. This page keeps that clean: https://casinofavoriter.com/. Compare options, then pick a table that fits the chart you use.

Mini FAQ

Is there one basic strategy for all blackjack games?

No. The core is the same, but a few cells change with rules. H17 vs S17, DAS vs no DAS, and surrender change the best move in some spots. Check the header above the chart before you play.

Should I hit or stand on hard 16 vs 10?

With late surrender: surrender. If surrender is not allowed: hit. Standing looks safe, but it loses too often.

When should I surrender?

Use late surrender on 16 vs 9, 10, A and on 15 vs 10. That is it for most 6-deck S17 games. If your rules are strange, re-check a chart made for those rules.

When do I double down?

Hard 11 vs 2–10 (hit vs Ace in S17). Hard 10 vs 2–9. Hard 9 vs 3–6. Soft 18 vs 3–6. Soft 17 vs 3–6. Soft 16 vs 4–6. Soft 15 vs 4–6. Soft 14 vs 5–6. Soft 13 vs 5–6.

Should I ever split 10s?

No. 20 is already strong. Splitting 10s gives up a near lock for two shaky hands.

Do I need to count cards to win?

No for basic play. Basic strategy aims to cut the edge, not flip it. Counting adds a bet spread and more moves. It also demands skill and good game rules. Many casinos do not like it. If you are curious, read research from the UNLV Center for Gaming Research.

Does online blackjack change basic strategy?

The plays are the same if the rules match. Live dealer shoes often use many decks and S17 or H17. Virtual games use RNG. Check the rules. Then use the right chart for that set.

Pocket recap

Five lines to carry in your head: always split A,A and 8,8; never split 10s; stand 12–16 vs 2–6 (except 12 vs 2–3 is a Hit); double 10 vs 2–9 and 11 vs 2–10; soft 18 doubles vs 3–6 and hits vs 9–A. Use surrender on 16 vs 9/10/A and 15 vs 10. Set limits. If play stops being fun, stop. Need help? Visit set limits and get support.

Table notes and printing tips

• Print tip: Save this page as PDF at 90% scale in portrait. Cut out the “Hard/Soft/Pairs” blocks as a pocket card.
• If no surrender at your table: replace all R with Hit.
• If H17 at your table: Double 11 vs Ace; A,8 vs 6 becomes Ds; a few other soft doubles may shift. Check an H17 version before play.
• Bankroll tip: Use flat bets while you learn. Track hands, not minutes. Take breaks.

Where this chart comes from

This chart is based on well-known sims and public math for 6-deck S17 games with DAS and late surrender. I cross-checked it with open sources and with live low-stakes hours. If you want to compare lines and EV for a given rule set, use the charts and calculators at Wizard of Odds and other math-first sites linked above.

Legal and safety notes

Blackjack may be illegal in your area or have age limits. Check your local law before you play. Basic strategy does not guarantee profit. It reduces the house edge. Do not gamble with rent or food money. If you feel stress while playing, stop and seek help.

About the author

I am a data nerd and a low-stakes blackjack player. I have logged 200+ hours at $5–$25 shoes and used trainers for 50+ hours. I test rules and note EV shifts, then turn that into short guides like this one. I do not sell systems. I update charts when rules or math notes change. Feedback is welcome.
