Blackjack Strategy Basics: Hitting, Standing, and Splitting

You sit at a blackjack table. Your cards are A,7. The dealer shows a 9. Do you hit or stand? Now try this: you have 8,8 and the dealer shows a 10. Do you split?

In this guide, you will learn fast rules you can use in under 20 seconds. You will also see why these rules work. There is a clear table you can keep by you. And you will get short practice hands to lock it in.

Quick answers first (20 seconds, then play)

If you need a move now, use this fast frame:

• Check your hand type. Hard hand = no Ace that can count as 11. Soft hand = Ace can count as 11.
• Look at the dealer’s upcard. 2–6 is weak. 7–Ace is strong.
• Pick the best action you can do. Sometimes you can double or split. If you cannot, use the next best step (hit or stand).

Short answer for most spots: hit hard 8–12, stand hard 13–16 vs dealer 2–6, and split A,A and 8,8. We add detail below and in the table.

Why basic strategy works at all

Blackjack has a house edge. But if you play with the right rules and the right moves, the edge gets small. With good rules and perfect play, it can be well under 1%. See a clear math view of the house edge with perfect play.

Rules at the table matter a lot. Some tables use “dealer stands on soft 17” (S17). Some use “dealer hits soft 17” (H17). Some let you double after split (DAS). These change the math. That is why any chart must say which rules it uses. If you want to read how rules get set in real rooms, see these standard blackjack rules (S17 vs H17, DAS) from a state regulator.

Your quick-reference table (for 6-deck, S17, DAS, no surrender)

This table fits these rules: 6 decks, dealer stands on soft 17 (S17), double after split (DAS) is allowed, no surrender. If your table has other rules, small changes may apply. We list key rule flips right after the table.

Notes: D = Double if allowed, else Hit. Pairs 2,2 and 3,3 split vs 2–7 here because DAS is allowed. If your table uses NDAS, split them vs 4–7 only. 4,4 splits vs 5–6 with DAS; if NDAS, just Hit 4,4.

How to read the table (and three common traps)

Use the row for your hand and the column for the dealer upcard. If the box says D but the table bans doubling, treat it as H. If it says P, split if you can. If splitting is not allowed (rare), use the hard total line for that sum.

• A,8 vs 6: In S17 rules, you Stand. Do not double here unless the table is H17 and you know the fine rule edge.
• 9,9 vs 7: Stand. Two 9s make 18. That beats a dealer 7 often enough. Many new players split and lose EV.
• 12 vs 3: Hit. Stand only starts at 12 vs 4–6.

Hit, Stand, Split: what each choice really does

Hit adds a card. It is right when your hand is weak and bust risk is low. With hard hands, hit a lot from 8 to 12. With soft hands (A counts as 11), hit more, since you often cannot bust on the next card.

Stand locks your total. It is right when the dealer is weak and your hand is “good enough.” A classic case is hard 12–16 vs dealer 2–6. You let the dealer draw and bust.

Split turns one hand into two. It is not “double the fun.” It is “fix a bad pair” or “boost EV.” You always split A,A and 8,8. You do not split 10,10. A pair of 10s is already 20. That is a strong stand.

All these choices change your long-term result, also called EV. If you want a simple intro to the math idea behind EV, here is a short guide on expected value.

Pro tip: When you feel fear of busting, look at the dealer first. If the dealer is weak (2–6), lean to Stand on 12–16. If the dealer is strong (7–A), lean to Hit those hands.

The dealer upcard is your lens

Think in two groups. Dealer 2–6 is weak. Dealer 7–A is strong. This one shift in view makes many spots clear at once. If you like a short read on this frame, see this dealer upcard framework.

• Hard 9–11: You want to double when the dealer is not strong. On 10, double vs 2–9. On 11, double vs 2–10 (hit vs Ace in S17).
• Hard 12–16: Stand vs 2–6. Hit vs 7–A.
• Soft A,x: Be more bold. A,7 doubles vs 3–6, stands vs 2/7/8, and hits vs 9–A.

Small rule flip note: If the table is H17 (dealer hits soft 17), two changes often pop up: A,7 vs A tends to Hit (same as here), and doubles with soft hands get a bit stronger in some spots. Check a chart made for H17 if you play that game.

Pairs: small list you can trust

• Always split A,A and 8,8. Even vs a dealer 10, split 8,8. Two hands that can reach 18+ beat one hard 16.
• Never split 10,10. You already have 20.
• 9,9: Split vs 2–6, 8–9. Stand vs 7, 10, Ace.
• 7,7: Split vs 2–7. Hit vs 8–A.
• 6,6: With DAS, split vs 2–6. Else, split vs 3–6 only.
• 5,5: Do not split. Treat as 10 and play like a 10.
• 4,4: With DAS, split vs 5–6. Else, hit.
• 2,2 and 3,3: With DAS, split vs 2–7. Else, split vs 4–7 only.

Pro tip: If you split, be ready to double on the new hands when the chart says so (this is why DAS helps your win rate).

Costly mistakes (and how to fix them)

Standing on hard 16 vs dealer 10 just to avoid a bust feels safe. It is not. You should Hit. On average, Hit loses less than Stand in that spot.

Splitting 10,10 because “the table is hot” burns money. You give away a great 20 and turn it into two weak hands. Do not do it.

Not reading the table rules is also costly. If you cannot double after a split, some pair plays shift. If the dealer hits soft 17, a few soft doubles change. Take 30 seconds to read the placard first.

Mini practice: 5 hands you can test now

Try to answer, then open the box.

Hit. Soft 18 vs a strong 9 is not strong enough. In S17 rules, Hit is best.

Stand. 18 vs 7 is good. Do not split here.

Hit. Stand starts at 12 vs 4–6 only.

Double. Soft 17 doubles vs 3–6. If you cannot double, Hit.

Split. Two hands from 8 beat one stiff 16 in the long run.

Online vs offline: small things that change the game

Live tables may use many decks or a shoe that never runs low. Online games use an RNG. Good sites follow strict code checks. You can read how labs and sites meet Remote gambling technical standards in the UK, as one clear example.

Rules also change by place and brand. Before you sit, check buy-in, decks, S17 vs H17, DAS, and if surrender is there. For a broad map of U.S. market notes, see state-by-state rule variations and industry guides.

Pro tip: Snap a pic of your chart and zoom it on your phone when you play online. It keeps your choices steady.

Bankroll and safer play

Set a budget for the day. Set a time cap. Take breaks. Basic strategy cuts the edge, but it does not make sure you win today. If play stops being fun, stop. For help and tips, see safer gambling advice. If you need to talk to someone, support if gambling is affecting you is there 24/7.

FAQ

What is a soft hand vs a hard hand?

A soft hand has an Ace that can count as 11 without busting. A,6 is soft 17. A hard hand has no Ace as 11. 10,7 is hard 17.

Do I always split A,A?

Yes, unless the table bans splitting Aces. Aces as two starts let you make 18–21 more often than one stiff 12.

What if my table is H17, not S17?

Use a chart made for H17. In short, soft doubles are a bit stronger at H17, and a few soft 18 spots change. The table in this guide is for S17.

Can I beat the house edge with basic strategy alone?

No. Basic play cuts the edge but does not flip it. To beat the game, players use skills like counting. That is beyond this guide and may be barred by house rules.

A last word and a fast recap

Think in three steps: know your hand (soft or hard), read the dealer (weak 2–6 or strong 7–A), then act (hit, stand, double, or split) by the table above. Use S17 vs H17 notes when you change tables. Keep a cool head. Small, steady edges in your choices add up over time.

Quick recap:

• Hard 13–16: Stand vs 2–6, Hit vs 7–A.
• Hard 9–11: Double in the ranges on the chart.
• Soft A,7: Double vs 3–6, stand vs 2/7/8, hit vs 9–A.
• Pairs: Split A,A and 8,8 always; never split 10,10; be choosy with 9,9, 7,7, 6,6, 4,4, 2,2, 3,3.
