1) What basic strategy actually means
Basic strategy tells you whether to hit, stand, double, split, or surrender based on your hand and the dealer’s upcard. It’s built from probability: the goal is to minimize losses (and maximize expected value) over thousands of hands.
2) The 80/20 rules beginners should memorize
- Always split A-A and 8-8.
- Never split 10-10 and 5-5.
- Stand on hard 17 or higher.
- With 11, double whenever the rules allow (especially vs 2–10).
- With 10, double vs dealer 2–9; otherwise hit.
- With 9, double vs dealer 3–6; otherwise hit.
- Dealer showing 4–6 is generally “weak”; 7–A is generally “strong.”
3) Hard totals vs soft totals (don’t confuse them)
A hard total has no Ace counted as 11 (example: 10+6 = hard 16). A soft total includes an Ace counted as 11 (example: A+6 = soft 17). Soft hands are safer to hit because the Ace can drop from 11 to 1 without busting.
Common beginner fixes
- Soft 17 (A-6) is not the same as hard 17. Soft totals often want hits or doubles depending on the dealer.
- Hard 12–16 is where most mistakes happen. The dealer’s upcard matters a lot.
4) Why splitting pairs is powerful (when done correctly)
Splitting converts one hand into two, which can increase your expected value in the right spots. The classic examples are A-A (you want two chances at 21) and 8-8 (hard 16 is a weak hand, but two 8’s can become stronger totals).
5) The biggest mistakes that cost players the most
- Staying in the hand too long (standing on weak totals vs strong dealer upcards).
- Doubling at the wrong time (or never doubling at all).
- Splitting “because it feels right” instead of following the correct spots.
- Chasing losses by increasing bet size without a plan.
6) Rules and table conditions matter
Basic strategy depends on rules. If a table pays 6:5 for blackjack instead of 3:2, the house edge jumps significantly. The number of decks, whether the dealer hits soft 17, and whether surrender is available also changes the math.
