How many spaces can a king move in chess?
A king can only move one space at a time in one single turn. However, castling is the only move in chess in which the king can move more than one space in a single move. In castling, the king and one of the rooks move simultaneously in a single move.
A king can move only one square or one step at a time in a single move but in any direction. So if all the surrounding squares next to a king are empty, then there are actually 8 possible ways you can move your king in any direction.
But remember, you can only move your king to any one of those possible squares in a single move.
Can a king move two spaces in chess?
A king can move two spaces in chess but only when the move is castling. In general, the king can only move one space at a time, in a single move. However, in castling, the king moves two spaces on either side along with rook of that side moving at the same time in a single move.
Castling is the only move that allows the king two steps. Rest, all the time in the game of chess, a king can only move one step at a time.
Can a king move 2.5 steps in chess?
No, a king can’t move 2.5 steps. The 2.5 steps that you are thinking about is actually the move of a knight. The knight moves in an L shape, two squares vertically and one square horizontally, or two squares horizontally and one square vertically.
The king can only move one step generally and only in castling it can move 2 steps. To know more about how the knight moves in chess read my complete article about it here
Can a king move diagonally in chess?
A king can move diagonally and in any direction but only up to one square. However, if the square where the king has to move is not empty and if moving to that square puts the king in check then the king can’t move diagonally to that square.

Can a king move backwards in chess?
Yes, a king can also move backwards in chess but only up to one square at a time. If the square where the king has to move is not empty or if moving to that square puts the king in check, then the king can’t move back to that square.
I also have an article on can chess pieces move backwards which I recommend you to check out if interested.
How does the king move in castling?
Castling is a special move in which the king moves two steps on either the right or left side, while the corresponding side rook moves just the opposite side of the king.
This is the only move in chess in which two pieces move simultaneously in a single move.
There are two types of castling, one is kingside castling and another is queenside castling.
Kingside castling is a type of castling in which the king moves two steps on its right side while the rook on that side just moves one step beside it on the left.
Queenside castling the king moves two steps on its left white the rook on that side moves one step beside it on the right.
I have already written an in-depth article on Kingside castling And Queenside castling, which you can check out for further information.
Now note that the king can’t move always in case of castling. There are four rules of castling you need to know.
- You can’t castle if the king or rook has already been moved once.
- You can castle only if the space between the king and the rook is vacant.
- You can’t castle if your king is in check.
- You can’t castle if the squares through which the king is going to pass through is under attack or the squares on which the king is going to land is also under attack.
If you follow the above four rules then only the castling would be considered a legal move. Also, remember that you can’t do castling with two hands as it is illegal.
What is the position of the king in chess?
A king is the tallest chess piece and can be identified by the crown with a cross on the top. There is a total of two kings in chess and both of them are placed on the e file, one on the first row and another on the last row, facing each other.
As you can see, the white king is placed on the e-file square in the first row while the black king is placed facing exactly opposite it, in the last row. Also, the king is placed between the queen and the bishop.
In chess, the horizontal rows are called ‘ranks’ whereas the vertical columns are called ‘files’. There are 8 ranks denoted on the side of the chessboard using the numbers 1-8.
While the files are denoted by the English alphabet from a-h. So on the e-file square of the first and the last rank, the kings are placed.
How do the king attack and capture in chess?
A king can attack and capture, any opponent piece standing next to it as long as doing that doesn’t put it in check. However, one king can’t capture another because doing that also puts the first king in check which is illegal.
This concept of one king can’t approach another king is also known as ‘opposition’. So in simple words just remember that one king always opposes the enemy king.
I have already written an in-depth article on can a king capture another king in chess, which you can check out for more information.
The golden rule regarding the king in chess: Always remember you can’t leave your own king in check (under attack), neither you are allowed to make a move that puts the king in check or exposes it to check.
As you can see in case – 1, the king can’t capture because doing that, would not put the king in check. So no rules will be violated.
But in case – 2, the king can’t capture because the white queen is supported by the white rook. So the king would be in check if it tries to capture the white queen, which is illegal.
You can read more about this in my article can the king kill in chess.
Can a king move 2 spaces to kill in chess?
A king can’t move 2 spaces to kill in chess. A king can only move one space to kill any chess piece. Even while castling, when the king is allowed to move 2 spaces, the king can’t capture any piece because it will be illegal to do so.
The reason for it is because the piece is to be captured while the king castles will be present between the king and the rook.
And as per the standard rules, castling is temporarily prevented if there is any piece between the king and the rook with which castling is to be effected.
So, since it is not allowed to castle your king in such a situation, you are also not allowed to move your king to 2 spaces to kill any other chess piece.

Some important concepts related to king
In simple words, check means when the king is in threat. So whenever you are in check that means you are being attacked by your enemy pieces.
Here in the above image as you can see, the white queen has attacked the black king. So in chess terminology, it would be said that the black king is in check
However, you don’t need to worry because there are three ways to escape from this check.
- Moving the king away, out of the danger zone
- Blocking the attack by keeping a piece between the attacking piece and the threatened king
- By capturing the attacking piece.
In the above image as you can the only way left for the blacking to escape from the check is to move the king away to a safer square (the safer squares are marked in the images with green ticks).
Here blocking the check or capturing the attacking chess piece is not possible.
You can read more about all these in my article do you have to move your king in check.
It is a situation in which the king is in attack (check) but it is not possible to the king out of it. So whenever a checkmate occurs then it means you have lost all hope of saving the king.
As you can see the black king is attacked by the white queen (which means the black king is in check). But there are no ways left to take the black king out of the threat.
Think of the three ways to escape check I discussed with you earlier and analyze why they are not applicable. If you are thinking that the black king can kill the attacking chess piece, the white queen, then you are wrong!
This is because the white queen is supported by the white bishop (refer to the image). So as soon as the king kill the queen, the king would again get into check due to the white bishop.
And as we know it is illegal to move your own king in check, so here the black king can’t get out of check. This is how here checkmate occurs.
Whenever a king checkmated the game ends immediately. The player who gets checkmated loses while the player who does the checkmate wins the game.
You can read more about checkmate rules here.
Now there is another case that occurs in which the player’s king is not in check but the player has no legal moves left to continue the game. This condition is known as a stalemate.
Whenever this occurs, the game ends in a draw immediately. As you can see in the image the black king is not in check. But there are no squares left where the black can move the king.
Also, the black pawns are also blocked. Since the pawns can’t move because there is an enemy piece in front of each one of them.
So in all, there are no moves left for the black to make, isn’t it? Thus the game ends in a draw.
