Quick Answer
Key concepts at a glance
Basic strategy is the mathematically optimal way to play every blackjack hand. With player 16 vs dealer 10, hit. With 11 vs 6, double down. With A-8 (soft 19) vs any card, stand. Following basic strategy reduces the house edge to as low as 0.5% depending on table rules. Memorizing it takes practice but can save you thousands in the long run.
Key Basic Strategy Rules
Essential rules to memorize
- Basic strategy reduces house edge to 0.5% or less with favorable rules
- Always split Aces and 8s, never split 10s or 5s
- Double down on 11 against dealer 2-10
- Stand on hard 17+, hit hard 12-16 vs dealer 7+
- Soft hands (with Ace) play more aggressively - double more, hit more
- Surrender 16 vs 9, 10, A and 15 vs 10 when allowed
- The dealer must follow strict rules - use this to your advantage
Frequently Asked Questions
Common questions about basic strategy
What is blackjack basic strategy?
Basic strategy is the mathematically optimal way to play every possible blackjack hand combination against every dealer upcard. It was developed using computer simulations of millions of hands and tells you when to hit, stand, double, split, or surrender to minimize the house edge.
Why does basic strategy change based on rules?
Different rules change the math. If the dealer hits soft 17, it slightly increases the house edge and affects some marginal plays. If you can double after splitting (DAS), it makes splitting more valuable in certain situations. The number of decks also affects optimal play.
Should I always follow basic strategy exactly?
Yes, unless you are card counting and adjusting for the true count. Basic strategy is mathematically optimal for a neutral deck. Hunches and feelings have no mathematical basis and will cost you money over time. Even small deviations add to the house edge.
What is the most important rule to remember?
Never take insurance or even money - it's a sucker bet with a 7.7% house edge. Also remember to always split Aces and 8s. These two rules alone save significant money. After that, focus on hard totals 12-16 vs dealer 7+ (hit) and when to double (11 vs 2-10).
How long does it take to learn basic strategy?
With dedicated practice, most people can memorize basic strategy in 1-2 weeks. Start with the hard totals, then soft hands, then pairs. Use flashcards or practice tools. The goal is instant recall without hesitation at the table.
