What is basic strategy in blackjack?

Basic strategy is the single most valuable thing a blackjack player can learn. It is not a betting system or a secret - it is simply the best possible move for every hand, calculated by running millions of simulations, and it turns blackjack into one of the fairest games in the casino.

Quick answer: Basic strategy is the mathematically proven best decision for every possible hand you can hold against every card the dealer can show. It was worked out with computer simulations and is usually shown as a color-coded chart. Following it perfectly reduces the house edge to about 0.5%, without any card counting required.

What the chart tells you

A basic strategy chart lists your hand down one side and the dealer's upcard across the top. Where they meet, it shows the correct action: hit, stand, double, split or surrender. Because the dealer follows fixed rules, there is always one best answer, and the chart never guesses.

Why it works

The chart is built from the exact probabilities of every outcome, so it always picks the play with the highest long-term value. It will not win every hand - nothing can - but it guarantees you are never leaving money on the table. See the full grid in our strategy guide.

Learning it painlessly

Start with the high-impact rules: always split Aces and 8s, never split 10s, double 11, and stand on hard 17 or more. Fill in the rest with practice. Because our tables are free, you can drill the chart hand after hand on Classic Blackjack until it becomes second nature.

Do you hit or stand on 16 in blackjack?

It depends on the dealer's upcard. Stand on a hard 16 when the dealer shows a weak card, 2 through 6, and hit when the dealer shows a strong card, 7 through Ace. If surrender is offered, give up 16 against a dealer 9, 10 or Ace. A pair of 8s that makes 16 should be split, not played as a 16.

When should you double down in blackjack?

Double down when the odds favor putting more money on one strong hand. The best spots are a hard 11 against almost any dealer card, a hard 10 when the dealer shows 9 or lower, and a hard 9 against a dealer 3 through 6. You get exactly one more card, so only double when a single card is likely to build a winner.

How do you win at blackjack?

You win more consistently by playing correct basic strategy on every hand, not by chasing 21. That means standing on stiff hands when the dealer is weak, doubling 11 and splitting Aces and 8s, never taking insurance, and choosing good-rule tables. You cannot erase the house edge, but smart play cuts it to about 0.5%.
