Blackjack Strategy Guide: Basic Strategy, Odds and Tips

Blackjack Rules in One Minute

• Cards 2–10 count at face value; J, Q and K count as 10; Ace counts as 1 or 11.
• You and the dealer start with two cards. One dealer card is face up.
• You can hit (take a card), stand, double (double your bet and take one card) or split a pair into two hands.
• If you go over 21, you bust and lose immediately.
• The dealer must draw to 16 and stand on 17 (rules on soft 17 vary).
• A two-card 21 (Ace + 10-value card) is blackjack and usually pays 3:2.

Why Basic Strategy Matters

Basic strategy is the mathematically best decision for every combination of your hand and the dealer’s up card, worked out by computer simulation. Using it reduces the house edge from around 2% for an average player to about 0.5% under typical rules. You do not need to memorise every cell at once – start with the key rules below.

Rules vary slightly between tables, so treat this as a strong general guide.

9 Things to Know About Blackjack Strategy

1. Never take insurance. It is a side bet on the dealer having blackjack and carries a high house edge.
2. Assume the hidden card is a 10. Many decisions make sense once you remember that 10-value cards are the most common.
3. Stand on stiff hands against weak dealer cards. Let the dealer bust when showing 4, 5 or 6.
4. Double aggressively on 10 and 11. These are your strongest doubling hands.
5. Look for 3:2 blackjack payouts. Tables paying 6:5 increase the house edge significantly.
6. Avoid side bets such as Perfect Pairs and 21+3 unless you accept their higher edge.
7. Do not change strategy after losses. Basic strategy is correct every hand.
8. Use flat betting. Progressive systems do not change the odds.
9. Know when to stop. Even at 0.5% edge, the house wins over time.

Card Counting and Shuffle Tracking

Card counting keeps a running tally of high and low cards to estimate when the remaining shoe favours the player. Shuffle tracking tries to follow groups of cards through a shuffle. Both can work in theory at physical tables with deep penetration, but online live tables use multiple decks and frequent shuffles or continuous shuffling, which makes them impractical. For most players, perfect basic strategy is the realistic goal.

Common Blackjack Mistakes

• Hitting 12 against a dealer 4, 5 or 6.

• Taking insurance "to protect" a good hand.
• Chasing losses with bigger bets – a classic way to lose a bankroll fast.
