The Different Rules About Castling in Chess

Known for its challenging rules and principles, chess is definitely one of the most favorite recreational activities of all time. Throughout history, several modifications were made to the rules of the game for countless times already. Some rules were added while the others were removed to make the game more fun and exciting to play. Despite these changes, the beauty and character of the game are still preserved up to this present moment.

One of the most interesting rules of chess involves castling. This concept is a special maneuver wherein the king and rooks are used for defensive purposes. Known to have originally started in the European continent between the 14th and 15th centuries, this move can be either a kingside or a queenside castling. Before such move is possible to make, players must be able to clear out the squares between the king and the rook.

A castling is called kingside when the chess pieces used to make the move are the king and the rook that is nearest to it. It is also referred to as castling short, describing the shorter distance between the king and the rook. On the other hand, a castling is called queenside when the chess pieces utilized in the move are the king and the rook that is nearest to the queen. Players refer to it as castling long because of the longer distance between the king and the queen-side rook.

The two chess players involved in the game can perform a castling. However, this defensive tactic can only be used once in every game, with some conditions to be considered. All of these requirements should be met in order to be eligible for a castling move. Primarily, a player's king must not be moved in the previous occasions. At the same time, the rook that is to be used in executing the move must not be moved also. If any of these two conditions are not met, castling is simply not permissible.

Another requirement before a possibility of castling is that the king must not be threatened at that very moment. It means that it is not possible to make this move when the opposing player is checking the king. Furthermore, the spaces covered by the castling move must not be under direct attack from the chess pieces of the other side. Simultaneously, castling is possible only when the king and the desired rook belong to the same level.
