resplitting

Some games allow unlimited resplitting, while others may limit it to a certain number of hands, such as four hands (for example, "resplit to 4").

Resplitting of aces permitted: At most casinos, the player who splits aces receives only one more card on each ace.

Allowing the player to hit hands resulting from split aces reduces the house edge by about 0.13%; allowing resplitting of aces reduces house edge by about 0.03%.
