If either player abandon the game by quitting the table in anger, or in an otherwise offensive manner; or by momentarily resigning the game; or refuses to abide by the decision of the Umpire, the game must be scored against him.
In Castling, the King must be moved first, or before the Rook is quitted. If the Rook be quitted before the King is touched, the opposing player may demand that the move of the Rook shall stand without the Castling being completed.
A player is said to have the opposition when he can place his King directly in front of the adverse King, with only one square between them. This is often an important advantage in ending games.
Each player, it will be observed, has eight superior Pieces or officers, and eight minor ones which are called Pawns; and, for the purpose of distinction, the Pieces and Pawns of one party are of a different color from those of the other.
A Pawn reaching the eighth square must be at once exchanged for any piece of its own color (except the King) that the player of the Pawn may elect.
