Why should you do the castle move in chess?

Answer 1

You should castle in order to protect your king by tucking it into the corner behind a wall of pawns with the rook guarding the entrance. A king left in the center of the board during the game will soon become target practice for the other player. In addition it links up the two rooks or at least prepares them to be linked up. Two rooks on the same rank or same file make a powerful combination of pieces both for offense and defense. Castle early if you can unless for strategic reasons you want to keep your opponent guessing as to whether you will castle kingside or queenside. Some players like to let the opponent mount an attack on one side, then castle to the other side.

Answer 2

Castling is good, because:

1. It helps defend your king.

2. It can bring out a rook into the board.
