The term 'High Cards in Bridge' refers to the four ACES, which are the highest-ranking cards in the game of Bridge. These cards are considered to be the most powerful cards in the deck and can be used to win a hand. The ACES are also known as the top trump cards, meaning that they will always beat any other card in the deck. In Bridge, the ACES are usually the first cards to be played, and they can be used to take control of the game.
