What is blackjack basic strategy?

Basic strategy is the set of plays that minimizes the house edge in blackjack. It is derived from computer simulations of millions of hands and tells you the correct action (hit, stand, double, split, surrender) for every possible player hand vs. dealer upcard combination.

Does this chart work for all blackjack variants?

This chart covers standard multi-deck blackjack (4–8 decks) with dealer standing on soft 17, which is the most common casino ruleset. Single-deck or S17 games have small differences — always check the specific table rules.

What does "soft" hand mean?

A soft hand contains an Ace counted as 11 without busting. For example, Ace+6 is a soft 17. Because the Ace can also count as 1, you cannot bust by taking one card — this changes the optimal strategy compared to a hard 17.

When should I surrender?

Late surrender (when available) is correct for hard 16 vs. dealer 9, 10, or Ace, and hard 15 vs. dealer 10. Surrendering gives up half your bet but saves money long-term in those high-risk spots.

Why should I always split Aces and 8s?

Splitting Aces gives two chances to hit 21. Splitting 8s converts a terrible hard 16 into two hands each starting at 8, which play much better against any upcard. These are the two splits that always apply regardless of dealer upcard.
