Understanding Blackjack Strategy

Basic blackjack strategy is a mathematically calculated approach that gives players the optimal play for every possible hand against every possible dealer up card. This strategy minimises the house edge and maximises your chances of winning.

Basic Strategy Key Principles
  • Always split Aces and 8s - This maximises your expected value
  • Never split 10s or 5s - 10s are already a strong hand, and 5s are better played as one hand
  • Double down on 11 - Unless the dealer shows an Ace, always double down on 11
  • Stand on 17 or higher - The risk of busting is too high to hit
  • Hit on 12-16 against dealer 7 or higher - When the dealer has a strong up card, you need to take risks
  • Always hit soft 17 or lower - You cannot bust with a hit on a soft hand
Terms and Definitions
  • Hard Hand: A hand without an Ace, or with an Ace counted as 1
  • Soft Hand: A hand with an Ace counted as 11
  • Blackjack: An Ace and a 10-value card as the first two cards
  • Push: A tie with the dealer, your bet is returned
  • Double Down: Double your bet and receive exactly one more card
  • Split: Divide a pair into two separate hands, each with its own bet
  • Surrender: Give up half your bet and end the hand immediately

Disclaimer: This calculator uses standard basic strategy which offers the mathematically optimal play in most situations. While following basic strategy reduces the house edge to its minimum, it does not guarantee winning any specific hand. In real casino play, factors like rule variations, card counting, and bet sizing also influence long-term results.
