Castling stands out as the only move in chess that allows a player to reposition two pieces at the same time. Invented in the 16th century, it requires the king and rook to be resting in their original positions with no pieces in between. The king must also be free from threat in his original position, his new position, and the intermediate square.
To castle, the king moves two squares in the direction of the rook on his own side or three squares in the direction of the rook on the queen’s side. The relevant rook then moves to occupy the square through which the king passed. The king then occupies a more protected spot near the corner of the board. Experts advise players to perform this protective maneuver early in the game and to keep pawns close as long as possible for extra security.
