..... There aren't opponents in blackjack. just the dealer and the players. If 2 players both have 21, and the dealer doesn't they both win regardless of what cards they have.
An ace counts as 11 in blackjack when it can be used without causing the player to bust, or exceed a total of 21.
Blackjack, that is an Ace with any 10 value card.
In blackjack, when the dealer has an ace, they must check if they have a blackjack (a total of 21 with their first two cards). If the dealer has a blackjack, the game ends and players lose unless they also have a blackjack. If the dealer does not have a blackjack, they must continue playing according to specific rules set by the casino, such as hitting or standing based on their total card value.
When a blackjack dealer has an ace, they must count it as 11 unless doing so would cause them to bust (go over 21). If counting the ace as 11 would cause them to bust, they must count it as 1. This decision is made based on the total value of the dealer's hand.
When playing blackjack and the dealer shows an ace, it is generally recommended to stand rather than hit. This is because the dealer has a higher chance of getting a strong hand with an ace, and hitting could result in going over 21.

In Black Jack, the Ace of Spades is worth the same as any other Ace, 1 or 11, as needed. It has no special meaning. A "Black Jack" is any combination of two cards that total 21, so it is any Ace plus any face card or ten.
