If you’re new to chess, castling can look like an illegal move at first because two pieces move at the same time. But this is a legal and very important move in chess! Watch this free lesson on castling, or read on below!
So maybe we can look into a game and understand how it works in practice? VK: (Kramnik goes on to show a very interesting game in No-Castling chess of Alpha-zero against itself and draws attention to some specific moments where he thinks the variant is markedly different from the regular version) Alpha Zero versus Alpha Zero, No-Castling Chess. Castle Kingside (King e1 to g1). Should work just perfectly. Also go to versiontracker.com and check out Sigma Chess. It's a cool program that can be a bit easier than Chess for Mac OS X (if you choose), and you can replay games and stuff. I like it a lot.-Prachi.
Castling is the only time in chess that two pieces can move at once, and the only time a piece other than the knight can move over another piece! The king moves two spaces to the left or to the right, and the rook moves over and in front of the king! All in one move!
To castle, simply move the king two spaces to the left or right, OR move the king on top of the rook you want to castle with. The rook will jump across and to the other side of the king automatically!
You can’t castle any time you want to, though. Here are the rules for castling:
- Your king can not have moved! Once your king moves, you can no longer castle, even if you move the king back to the starting square. Many strategies involve forcing the opponent’s king to move just for this reason!
- Your rook can not have moved! If you move your rook, you can’t castle on that side anymore! Both the king and the rook you are castling with can’t have moved!
- Your king can NOT be in check! Though castling often looks like an appealing escape, you can’t castle while you are in check! Once you are out of check, then you can castle! Unlike moving, being checked does not remove the ability to castle later!
- Your king can not pass through check! If the square the king moves over, or moves to would put you in check, you can’t castle! You’ll have to get rid of that pesky attacking piece first!
White is not allowed to castle through the bishop's 'check' on f1!
- No pieces can be between the king and rook! All the spaces between the king and rook must be empty! This is part of why it’s so important to get your pieces out into the game as soon as possible!
It is never a good idea to disobey chess principles. Although we live in modern days, where the powerful engines have taught us that in chess the principles or “rules” are not always mandatory, for a human it’s helpful to have an understandable guide on how to play the opening phase.
Therefore, the principles are useful, shortlist of to-do things. Fight for the center, develop your pieces and secure your king by castling. However, sometimes this can get you into trouble without even noticing it.
The main problem is that once you’ve castled you are first to show your cards and sometimes your opponent is able to begin an attack against your king, already committed to his new place. In this article, we will deal with this subject and next you will find explained examples of this theme.
The first example is one of my own games against the Grandmaster from Georgia Alexandre Dgebuadze. I didn’t play the opening particularly well and after just 10 moves we arrived in the following position:
Black is clearly under pressure.
The dark squares look potentially weak after the imminent trade of the dark-squared bishop. Certainly an important moment in the game. In the game black was naïve enough to think that castling would be fine, underestimating the chances of white for a direct attack along with the H-file.

A common example of this theme is often seen in the London System after the moves: https://axisever693.weebly.com/kryptology-escape-game-pigeon-forge.html.

In the diagram above black has just castled and although it is not a deadly mistake, it gives white excellent chances for an attack against the black king. It would have been better, to begin with, c5 or b6, Bb7 as in the game, but keeping the king in the center until white defines first what he is going to do with his own king.

A few moves later White had already developed a very dangerous attack and even though black could have put up better resistance, I do not recommend playing like this.

Game 2: Castling too Early
There is no general rule about this except that one has to be careful at the time we make such an important decision in the opening. Every position has its own characteristics and we must evaluate well the possible dangers when castling before our opponent does.
A great, instructive example played at top level happened between two strong Ukranian players, with Ruslan Ponomariov as white and Alexander Areschenko as black:

In the position of the diagram above black played 9…0-0N which was also a novelty at the time. Had white been an inexperienced player, he would have also castled and the game would have continued with another characteristic.

However, Ponomariov started to make improving moves, such as 10.Be3 and 11.a4, developing and restricting the opponent’s play. It may seem routine to the eye of the club player but Ponomariov had already noticed a powerful idea – the rupture with g3-g4 could be very dangerous for black.
Even if white loses a pawn, the H file open would provide more than enough play for this minimum investment. Ponomariov went on to win the game in brilliant fashion, see it here:
