What are the specific movements and powers of the king and queen in a game of chess?

In Chess, the king can move one square in any direction, while the queen can move any number of squares in a straight line horizontally, vertically, or diagonally. The king's power lies in its importance to the game, as it must be protected at all costs. The queen is the most powerful piece on the board, able to control large areas and play a key role in attacking the opponent's pieces.
