King of the Hill or "KOTH" is an exciting variant in which the goal is to get your king to the center of the board or "top of the hill".
Rules
Games can still end in the traditional ways of checkmate, stalemate and time-out.
The game can also end when a player moves their king to any of the four central squares.
e4, d4, e5, and d5 are "top of the hill" squares. Move your king onto one of those squares to win the game on the spot for either White or Black, regardless of the nature of the position.
