A player's King is in check when the force of an opponent piece is directly exposed toward the player's King.
A player's King is checkmated when a check cannot be resolved by moving the threatened King, capturing the threatening opponent piece (or pieces), or interposing a piece between the player's King and the threatening piece (or pieces).
No player may make a move that, by that move, as of the moment, exposes that own player's King to the force of check or checkmate.
A piece or pawn is "pinned" and cannot be moved if its movement immediately results in the exposure of that player's own King to check or checkmate.
A player is in a condition known as "stalemate" if that player cannot move any piece, or cannot move a piece without exposing that player's own King to an immediate check or checkmate.
If only two players are on the board and the conditions for Stalemate are met, the game ends in a Stalemate. If three or more players are on a board and the conditions for Stalement are in effect for a player, that player is in Stalemate (and that player's King is removed from the board), but the other players continue the game.
If a player meets the conditions for Mate or Stalemate, that player's King is removed from the board, but the remaining pawns and pieces remain as physical obstacles (which may then be captured and removed by other active players).
The Sovereign Territory of a mated or stalemated King must not be entered by any piece in play.
If a pawn enters an opponent territory, and is not promoted before the King of that territory is mated or stalemated, that pawn is forfeit at the moment of mate or stalemate and must be removed from the board before play can resume.
Any piece (other than a pawn) which is located in the Sovereign Territory of a King at the moment the King is mated or stalemated, may remain in the Sovereign Territory as an active piece, but the next time that piece moves, it must leave the territory, if possible, capture an inactive opponent piece, if necessary toward leaving the territory, or capture an active opponent's piece. If none of these actions occur when the piece is moved within the territory, the piece is forfeit and is removed from the board.
Any piece in an inactive territory, when moved, must leave the territory in the minimum number of possible moves unless it is capturing another active player's pieces prior to leaving the territory.
