What the chart recommends
A basic strategy chart matches the player’s hand with the dealer’s upcard and indicates a decision for that situation. Common options are hit, stand, double down, or split a pair; some charts also include surrender when the table rules allow it. The recommendation is based on statistical analysis, not a prediction of how a particular round will end. Basic strategy aims to reduce the house edge compared with intuitive decisions, but it does not remove that edge or guarantee wins.
The chart compares the available choices using the known cards. Basic strategy is not card counting or a betting-sizing system: the indicated play depends on the player’s hand and the dealer’s visible card.
Finding the right decision
To use a basic blackjack strategy chart, first identify the hand type shown along the side: hard total, soft total, or pair. Then find the dealer’s upcard across the top and read the cell where the row and column meet. A soft hand has an ace that can count as 11 without taking the total over 21; a hard hand has no ace, or the ace must count as 1. Treat a pair as a pair, not merely as its combined total: for instance, 6,6 is a pair, while ace,5 is a soft hand.
Abbreviations vary by chart. Commonly, H means hit, S means stand, D means double, and P means split. A combined instruction may depend on a table rule—for example, double if allowed and otherwise hit or stand. Check the legend before following a cell; do not assume that symbols mean the same thing in every version.
Rules and limits
There is no single chart for every game: recommendations can change with the number of decks and table rules, including whether doubling, splitting, or surrender is allowed. A chart labeled for multiple decks should not automatically be used for a single-deck game, or the other way around. Use a version that matches the rules actually shown at the table, and read those rules rather than relying on the chart alone.
