Blackjack Basic Strategy: A Complete Cheat Sheet for Beginners
Walk into the gaming floor at Crown Melbourne on a Friday arvo and you'll spot clusters of punters leaning over green felt tables, all trying to outsmart the dealer. Blackjack remains a favourite among Australian casino-goers because the rules are simple, the rounds move quickly, and unlike spinning a pokie, every decision you make actually shifts the odds. For anyone stepping up to the table for the first time, learning basic strategy turns a casual gamble into a calculated contest.
Basic strategy is a set of mathematically derived rules that tell you the best move for any hand against any dealer up card. Researchers ran computer simulations of millions of hands to determine whether you should hit, stand, double down, or split. Followed perfectly, the strategy cuts the house edge to roughly half a percent, making blackjack one of the fairest games at venues like Star Sydney or SkyCity Adelaide.
A cheat sheet condenses those calculations into a one-page reference you can glance at while playing. Beginners often worry that using a chart feels like cheating, but casinos don't ban basic strategy cards because they reward memorisation and thoughtful play, not luck. The sheet simply removes guesswork when you're juggling your own cards and the dealer's showing card.
This guide covers hand classifications, hit and stand rules, doubling decisions, splitting pairs, and how to read the dealer's up card. By the end, you'll have a printable chart and the confidence to play at any Australian casino table without second-guessing every move.
Hard Hands and the Decision to Hit
A hard hand contains no ace, or contains an ace counted as one. These totals are tricky because there's no flexibility to bend the value of your cards. With a hard 8 or lower, you always hit, since busting is impossible. Hard 9 doubles against dealer weak cards (2 through 6) and hits otherwise. Hard 10 and 11 are prime doubling territory when your total beats the dealer's up card.
The awkward middle zone, hard 12 through 16, is where most beginners make costly errors. The cheat sheet tells you to stand against dealer 2 through 6 and hit against 7 through ace. Low dealer cards mean the dealer is more likely to bust, while high dealer cards mean you must improve your hand to compete.
| Hard Total | Dealer 2-6 | Dealer 7-A |
|---|---|---|
| 8 or less | Hit | Hit |
| 9 | Double | Hit |
| 10-11 | Double | Double |
| 12-16 | Stand | Hit |
| 17 or more | Stand | Stand |
Hard 17 or higher is an automatic stand. Even though the dealer might still beat you, the risk of busting outweighs the potential gain.
Soft Hands: Flexibility With the Ace
A soft hand contains an ace counted as eleven, giving you built-in insurance against busting. The most common soft totals are A-2 through A-9, written as soft 13 through soft 20. The ace's dual value lets you be more aggressive than with hard hands of the same number.
Hit or double soft 17 (A-6) against every dealer up card. With soft 18 (A-7), double against dealer 2 through 6, stand against 7 and 8, and hit against 9, 10, and ace. Treating soft hands too conservatively leaves value on the table. Soft 19 and soft 20 are always stands, since hitting them usually weakens your total.
Doubling Down for Maximum Value
Doubling down lets you double your original bet in exchange for committing to exactly one more card. Hard 10 and 11 are classic double-down situations when they beat the dealer's up card. Avoid doubling when the dealer shows a strong 9, 10, or ace, since their likely made hand will punish your single-card draw.
Soft doubles come into play with hands like A-5 through A-7. Double A-5 and A-6 against dealer 3 through 6, and double A-7 against dealer 3 through 6. Always double soft 13 through 17 against dealer 5 or 6, the worst up cards for the house.
Splitting Pairs: Strategic Breaks
Splitting turns one bad hand into two potential winners, but only when the math supports it. Always split aces and eights: a pair of aces gives you two shots at 21, while splitting eights escapes the dreaded hard 16. Never split tens or fives; tens already make a strong 20, and fives belong in a double-down position as a hard 10.
Split twos, threes, sixes, and sevens against dealer 2 through 7. Split nines against dealer 2 through 9 but stand against 7. Most Australian tables allow doubling on any two cards but restrict doubling after splitting, so read the placard before you sit down.
Reading the Dealer's Up Card
The dealer's visible card drives every basic strategy choice. Cards 2 through 6 are weak, statistically busting more often than they make pat hands. Cards 7 through ace are strong, meaning you must build a hand that beats a likely 17 to 21.
Bust probabilities underpin every recommendation in your cheat sheet. Dealer up card 6 busts about 42 percent of the time, 5 busts around 43 percent, and 2 busts roughly 35 percent. These percentages explain why standing on hard 12 through 16 against low cards works, and why doubling becomes profitable when the dealer's showing card is most likely to fail.
