About Basic Strategy

Basic strategy is a mathematically proven set of decisions that minimizes the house edge. It’s not card counting (which is illegal in casinos), it’s simply playing each hand the way probability suggests is most likely to win.

Key principles:

• Always Split Aces and Eights -Never split 5s, 6s, or 10s
• Double Down Strategically – Usually on 11 against most dealer cards, and on 9-10 in specific situations
• Soft Hands Matter – Hands with an Ace are more flexible and have different strategy
• Dealer Busts Often – When the dealer shows 2-6, they bust more frequently, so you should be more conservative

Customizable Rules

Different casinos have different blackjack rules. This calculator accounts for:

• Nombre de ponts : 1 to 8 deck shoes (affects odds)
• Dealer Hits on Soft 17: Some casinos require dealers to hit on soft 17, others stand
• Double après fractionnement : Whether you can double down after splitting
• Resplitting: Whether you can split more than once
• La reddition : Available in some casinos to forfeit your hand for half your bet

Why Strategy Matters

Using basic strategy reduces the house edge to approximately 0.5%, compared to casual players who might face a house edge of 2-4%. Over time, better decisions lead to better results.

Remember: This calculator provides optimal strategy recommendations, but blackjack always involves an element of chance. Gamble responsibly and never bet more than you can afford to lose.
