What is the significance of a king high in poker and how does it impact gameplay?

In Poker, a king high is a hand where the highest card is a king but the player does not have a pair or better. A king high can be significant in determining the winner of a hand when no players have a pair or better. It impacts gameplay by giving the player with the king high a stronger hand compared to those with lower high cards, such as a queen high or a jack high. This can influence betting decisions and strategy during the game.
