Double Down After Splitting
If the casino's blackjack rules allow you to double down after splitting, you will win more often. This means you should split more often. Here are the occasions where this is the best strategy:
When the Dealer's Up Card Is: |
Split a Pair of: | Instead of: |
2 | 6s, 3s, and 2s | Hitting |
3 | 3s and 2s | Hitting |
5 | 4s | Hitting |
6 | 4s | Hitting |
