What are the two aces in blackjack and how do they affect the game?

In blackjack, the two aces are valued at either 1 or 11 points each. They are considered powerful cards because they can be used flexibly to create a strong hand. If a player is dealt a hand with an ace, they have the option to use it as either 1 or 11 points, depending on what benefits their hand the most. This flexibility can greatly impact the player's strategy and chances of winning in the game.
