Allowing players to re-split aces has a small impact on the house edge and optimal strategy adjustments. The ability to re-split aces increases the player's chances of winning, as they now have more opportunities to make a good hand. However, this advantage is offset by the fact that the player is now playing two hands with a lower expected value.
In terms of optimal strategy adjustments, the player should now re-split aces whenever they are allowed to do so, as this increases their chances of making a good hand.
