Get her king to safetyMove your rook the end of the corner and also into the center of the game.

You are watching: What are the four rules for castling in chess

You can move the king two squares to one side, and then shift the rook right alongside the king on the opposite side. However, to be able to castle, the following rules must it is in fulfilled:

For the rook, it should be the very first moveFor the king, it need to be the an initial moveThe path between the king and also rook have to be clear (no pieces deserve to block them)The king cannot be under “check,” or need to not have actually passed one

If you lock in one direction, the king will obtain closer come the side of the chess board. This is called a “kingside castling.” If you castle to the other side, where the queen sits, that is referred to as a “queenside castling.” No matter what side it takes, the king will move only two squares when castling.

It is White’s move, and he may, if he wishes, castle brief immediately. However he calculates as follows: after ~ 1.0-0 Black will play …0-0, and also then how can I assault him? The piece by us can accomplish nothing in this blocked position. H3 and also g4 still have to be played and must be prepared by Qd2. Yet in the meantime, Black will consolidate his place on the kingside by method of g6 and also Rf8-f7-g7 after which the attack will have lost its power

There is no doubt that for an strike based on g4, White’s king is no well inserted at g1, and also it is much better for that function castle ~ above the queenside and then deploy the rooks ~ above the g-and h-files. However, if White chooses 1.Qd2 and then 2.0-0-0, Black can play 2…0-0-0, whereby upon the the attack with g4 no much longer applies. White will have to play a hasty b4, in which case it will be quickly seen the his king is badly inserted on c1. Consequently, he must put off castling and wait.

White thus plays 1.Qe2 and also if 1…0-0 climate 2.0-0-0, while if 1…0-0-0, climate 2.0-0. The castles top top the opposite side from black in order to obtain the maximum freedom for carrying out his attack.

4. Castling may be postponed, and also perhaps forgone for forever, in specific positions wherein the center is permanently blocked.

The factor for being able come postpone castling in such positions is, the course, that the pawns form an obstruction in the centre and so do it difficult to open up the main files and diagonals there is no painful sacrifices.

With the centre blocked, the majesties are likewise safer in the middle, at least for part time. The logical course of assault in such situations tends to be on the unblocked flanks, and also there room times once the king is more exposed by being in a castled position on the wing 보다 in the middle, whereby it is defended by the clogged pawns.

Here, if White plays 1.Qe2, Black’s best reply likewise consist that a postponement of castling, e.g 1…a6 or 1…Nd8. The postponement that castling is feasible for both sides in this position, and for a very obvious reason, the pronounce blockade in the centre.

Attacks deserve to only take place down the flanks and as a result, the emperors are in ~ the moment fairly safe in the middle. Play native this place might build as follows

1.Qe2 Nd8 2.h3 Nf7 3.Qd2 0-0-0

It is less dangerous for black color to castle on the queenside now. If White theatre 4.0-0, black color replies 4…Rdg8, threatening …g5, while after 4.0-0-0 the risk of an strike on the flank disappears and Black have the right to relax.

In this case, the preliminary skirmish has in fact finished with castling, but there are blocked positions whereby castling go not occur at all and the emperors stay permanently in the middle. Also in the over position, White has actually the alternate of no castling and instead coordinating his rooks by Kf2. Later on, that can also take his king approximately e3.

5.Castling is unnecessary, due to the fact that the endgame is currently not much off, in which situation the king is well placed in the center of the board.

These situations too room not infrequent in grasp chess. In this position, the white king forfeits the right to castle as a an outcome of exchange the queens.
