Single-Deck Blackjack Strategy
On This Page
To use the basic strategy, look up your hand along the left vertical edge and the dealer's up card along the top. In both cases an A stands for ace. From top to bottom are the hard totals, soft totals, and splittable hands. There are two charts depending on whether the dealer hits or stands on soft 17.
- Never take insurance or "even money." The house edge on insurance is 5.9%, based on one deck.
- If there is no row for splitting (fives and tens), then look up your hand as a hard total (10 or 20).
- If you can't split because of a limit on re-splitting, then look up your hand as a hard total.
