Rule variations can have a significant impact on the optimal blackjack strategy. For example, if the casino allows double after split, it can be advantageous to split pairs when the dealer's upcard is low, as this increases your chances of getting a good hand and allows you to double down on a favorable count. On the other hand, if the casino does not allow double after split, it may be better to avoid splitting pairs unless you have a very good hand. Similarly, if the casino allows re-splitting aces, this can be beneficial if you have a good count, as it increases your chances of getting a blackjack.
 
You are absolutely right that rule variations in blackjack can greatly impact the optimal strategy. The ability to double after split can indeed provide players with more opportunities to increase their bets on favorable hands. This allows for more aggressive play, especially in situations where splitting and doubling down are advantageous.

Re-splitting aces is another rule variation that can be advantageous to players. Being able to split aces again gives the player more opportunities to maximize their advantage, as splitting aces is one of the best moves in blackjack. This rule allows players to potentially create multiple hands with strong starting values, increasing their chances of winning.

Overall, understanding how rule variations like double after split, re-splitting aces, late surrender, and others can impact the game is crucial for optimizing your strategy and maximizing your chances of winning in blackjack. It's important for players to adapt their strategy to the specific rules of the game they are playing to gain the best possible edge against the house.
 
Rule variations such as double after split, re-splitting aces, and late surrender significantly affect optimal blackjack strategy. Doubling after splitting allows for more aggressive play with split pairs. Re-splitting aces gives additional chances to hit strong hands. Late surrender can reduce losses by allowing players to forfeit a hand and reclaim half their bet when facing unfavorable odds. Adjusting strategy to leverage these rules can improve a player's edge.
 
I feel variant allows players to surrender their hand and recover only half of the bet after the dealer checks for blackjack. However, players can't surrender if the dealer has an Ace up-card, they must have a hard 16, and they don't have an option for surrendering after deciding to hit or stand
 
After the dealer checks for blackjack, late surrender allows players to forfeit their hand and still receive half of their wager back. When the player has a weak hand against a strong dealer upcard, this option is advantageous.
