the male ruler of an independent state, especially one who inherits the position by right of birth.
King Henry VIII
the most important chess piece, of which each player has one, which the opponent has to checkmate in order to win. The king can move in any direction, including diagonally, to any adjacent square that is not attacked by an opponent's piece or pawn.
The first king to move must therefore step back from his pawn, leaving him no longer able to protect it (the rules of chess forbid the kings moving within one square of each other).
