Castling The King

Castling The King In Chess

Castling a king in chess is a special type of move in the game of chess that involves a king and a rook. To complete this process, you have to move your king two squares left or right on the first rank towards the rook, then move the rook to the other side of the square just next to the king that it crossed.

Castling The King In Chess

Castling is such an important step that is necessary for the security of your king. With this, both your rooks come closer and take your game to a better position. It also protects some weak pawns on your back rank.

So experienced players often attempt to set up an advantageous castled position for themselves. Castling always occurs under very specific rules, however, so beginners should avoid attempting it until they have learned those rules.

You can actually move two pieces at once with this unique chess move. It is the only move other than a knight that allows one piece to “jump” over another.

Castle Learning

The rules for castling are simple. First, you must move your king two squares toward a rook on your first rank (which is why it’s called castling). Then, you may move that rook to an empty square next to (but not diagonally) your king.

Note, castling cannot be done, if there is a piece between your king and rook. In chess, castlings can be made only once for each player per game.

Origins of Castling The King

Castling is a chess move that dates back to around 1100 when it was written about in an English manuscript. The earliest surviving evidence of castling comes from an Italian manuscript from the 13th century, but people believe that it originated much earlier than that.

The origins of castling aren’t entirely clear, but many historians believe that it evolved from a rule involving pawns.

The main reason for the creation of this rule is believed to be the long-term advantage of the chess strategy. Castling may have evolved to avoid having to use too many pieces on the king’s defense, so they tried to castle from the side of the board.

History of castling

The earliest recorded mention of castling appeared in an Italian manuscript from the 13th century. The Rules of Blodeling, written by a Flemish player Van der Linde in 1476, is considered to be one of the first treatises on chess.

He suggested that castling could only be made for white. White can castle but Black does not counter castles. Changes were made to this rule, and both sides can castling in the game today.

Castling Rules For Tournament

The rule of touch-move is in force in almost all tournaments in the world, based on this, castling is considered a king’s move, which is why the king must be touched first.

Castling Rules For Tournament

If you want to castle and you have accidentally touched the rook first, in this case, you cannot be castling, but you will have to make a rook move instead.

Under the current rules of the United States Chess Federation, a player wishing to castle, accidentally touches the rook first is still allowed to castle, provided the castling is legal. In such a situation, there is no provision of punishment for this chess player. However, the correct way is to move the king first.

Chess Without Castling

In 2019, former world chess champion Vladimir Kramnik had put a new type of idea in the world of chess. Accordingly, players will not be allowed to Castling.

Chess Without Castling

In this situation, the king is constantly in an unsafe position, which would theoretically lead to more decisive games. It would be quite difficult to force a draw in chess played with this idea.

In July 2021, a 4-game no-castling exhibition tournament between two former world champions Viswanathan Anand and Vladimir Kramnik was held in Dortmund.

Kramnik suffered a defeat in the first game, allowing Anand to win the tournament with a score difference of 2.5–1.5. Both the players called it a successful experiment.

Artificial Castling

This type of castling is also known as hand castling . A player uses this technique when his opponent moves his king or rook from his original initial position. This is such a trick in the game of chess, using which a player gets the position of the castle without being a castling.

Artificial Castling


Castling in chess is a special move that every player should know about because it helps protect your king and activate your rook. This allows you to defend against checkmate and get your rooks more involved in the game. If you are a beginner in chess, then I advise you to get castling as soon as possible.

The most common time to castle in chess is when you have one or more pawns ready to advance, as it’s often advantageous in getting your rook onto the open board faster so you can control more squares.
