What are the theoretical impacts of games dealing the hole card face-up or allowing dealer hit on soft 22?

Games that deal the hole card face-up or allow the dealer to hit on soft 22 can have several theoretical impacts on the game:

1. Dealer's hand: Knowing the dealer's hole card can significantly impact the player's strategy and decision-making. For example, if the dealer has a weak hand, such as a 12, the player may choose to stand on a weaker hand.

2. Expected value: The expected value of the game can change significantly depending on whether the dealer hits or stands on soft 22.

Absolutely, revealing the hole card face-up can give the player more information to make strategic decisions. For instance, if the dealer has a weak upcard and a strong hole card, the player may make different decisions compared to when the hole card is unknown.

Additionally, allowing the dealer to hit on soft 22 can increase the house edge. Since the dealer has the option to improve their hand even after reaching a soft total of 22, it gives them an advantage over the player. This rule can make it more difficult for the player to win in the long run.

Overall, these variations in the rules can make gameplay more interesting and strategic, but players should be aware of how these changes can impact their odds of winning.
