Blackjack Basic Strategy: The First Five Rules to Learn
Start building a sound blackjack game with five high-impact basic strategy decisions and the reasoning behind them.
The smartest place to begin in blackjack is not a betting system. It is basic strategy: the mathematically best decision for each hand based on your cards and the dealer’s upcard.
1. Always split aces and eights
Two aces are awkward as a total of 12, but each ace gives you a strong start for a new hand. A pair of eights totals 16—the weakest common hard total. Splitting gives both hands a chance to improve.
2. Never split tens
A total of 20 is already an excellent hand. Breaking it apart usually trades one very strong hand for two less certain ones.
3. Stand on hard 17 or more
With no ace counted as 11, hitting a total of 17 or higher carries a substantial bust risk. Basic strategy nearly always says to stand.
4. Treat the dealer’s 4, 5, and 6 as vulnerable
These upcards create more opportunities for the dealer to bust. With many borderline hands, the better play is to stand and let the dealer complete their hand.
5. Skip insurance
Insurance is a separate wager that the dealer has blackjack. Unless you are accurately counting cards, it carries a higher house edge than the main game.
Keep the chart nearby
Five rules are a start, not a replacement for the full chart. Rules vary slightly with table conditions, so use a chart made for the number of decks and whether the dealer hits or stands on soft 17.
Reality check: Basic strategy reduces the house edge; it does not remove it. Set a budget before you play and never chase losses.
