Question 1

What is basic strategy in blackjack?

Accepted Answer

Basic strategy is the mathematically optimal set of decisions for every possible hand combination in blackjack. It tells you when to hit, stand, double down, split, or surrender based on your hand total and the dealer's upcard. Following basic strategy reduces the house edge to approximately 0.5%.

Question 2

Does basic strategy guarantee you will win at blackjack?

Accepted Answer

No. Basic strategy minimizes the house edge but does not eliminate it. The casino always has a mathematical advantage. Basic strategy selects the action with the highest expected value for each hand, which means losing the least over time, not winning every hand.

Question 3

What is the difference between a hard hand and a soft hand?

Accepted Answer

A hard hand has no Ace counted as 11, or no Ace at all. A soft hand contains an Ace counted as 11, giving you more flexibility because you cannot bust on the next card. For example, Ace-7 is a soft 18, while 10-8 is a hard 18.

Question 4

When should you split pairs in blackjack?

Accepted Answer

Always split Aces and 8s. Never split 10s or 5s. For other pairs, the decision depends on the dealer's upcard. For example, split 2s, 3s, 6s, and 7s against dealer 2-7, and split 9s against dealer 2-6 and 8-9.

Question 5

How much does basic strategy reduce the house edge?

Accepted Answer

Without basic strategy, the average player gives the casino a 2-5% edge through suboptimal decisions. With perfect basic strategy, the house edge drops to approximately 0.5% under standard 6-deck rules (S17, DAS, 3:2 payout). That is a significant reduction of 1.5% to 4.5%.
