Quick answerBasic strategy is the best play for every blackjack hand. Six rules cover most situations and bring the house edge down to about 0.5%.
Six rules
| Your hand | Do this |
|---|---|
| 17 or more | Stand |
| 13 to 16 | Stand if the dealer shows 2 to 6; otherwise hit |
| 12 | Stand if the dealer shows 4 to 6; otherwise hit |
| 11 | Double |
| Aces or eights | Always split |
| Tens or fives | Never split |
Two things never to do
Take insurance, or play at a table that pays 6 to 5 for blackjack.
