The easy ones to remember:
- 2s, 3s, 7s – split when dealer shows 2-7
- 6s – split on dealer’s 2-6.
And the unique ones:
- 4s – are not a perfect hand for splitting, so you should split them only when the dealer shows 5 or 6 and only when you can double after split. If the casino doesn’t allow to double on split hands – never split 4s.
- 9s – split on dealer’s 2-6 and 8,9.
