Are you confused about whether a king can kill in chess or not? Then don’t worry, because in this article I’m going to explain case-by-case, when a king can kill a chess piece and when a king can’t kill a chess piece along with other related questions. Let’s start!
So, can a king kill in chess? Yes, a king can kill any attacking chess piece such as queen, knight, rook, bishop, or pawn, even in check. However, if the attacking chess piece is supported by another enemy piece, then the king can’t kill because that would put the king in check which is illegal.
Remember that one king can never check or attack another king directly. This is because as soon it tries to approach next to another king, it gets into check which is not allowed.
Hence one king can’t capture or kill another king. Read my detailed article about can a king kill a king in chess to know more.
Ahead I’m going to clarify all of your doubts along with the proper illustration, but before that let’s discuss how the king moves in chess (in brief).
How Does The King Move In Chess?
A king moves only one square in any direction provided that square is vacant and not controlled by another chess piece.
Here’s a video by Howcast that will help you to understand how the king moves in chess and all other related concepts.
Can The King Kill If In Check?
A king can kill if in check as long as doing that doesn’t put it in check again. Here’s an illustration that shows two cases of when a king can kill in check and when a king can’t kill in check.
Case – 1: When A King Can Kill In Check
As you can see in the image black king is in check and attacked by the white queen. So what would you do if you had the black chess piece?
Obviously, get your king out of check, right? Now there are three ways to get the king out of check.
- By moving the king into a safe square
- By placing any chess piece between the king and the attacking chess piece (here the white queen)
- By killing the attacking chess piece
Particularly, here we are discussing the third case, to kill the attacking chess piece. But is it possible? Before answering that, I want you to remember one rule from now onwards and that is:
One can’t leave one’s own king in check neither expose it to checkAs per the World Chess Federation (FIDE) rules
So any move you make that goes against this rule will be considered illegal and will be not allowed to make.
Now, I ask you can the black king kill or capture the white queen? The answer is yes because there is no threat in doing that, right?
Let’s discuss another case.

Case – 2: When A King Can’t Kill In Check
(See the image that I showed you earlier and come back again) So as you can see in case – 2 also the black king is attacked by the white queen.
But one thing if you noticed is that this time white rook is supporting the white queen. So can the king kill in this case?
The answer is no. This is because as soon as the black king will capture the white queen it will get exposed to check by the white rook.

And as I told you earlier, you can’t make any move that puts your king into check. Hence the king can’t kill in check in this case.
What Happens If You Move Your King Into Check?
It is considered an illegal move to move one’s own king into check. In casual games, nothing happens and you can just take back your move. But in professional games, after making two illegal moves you lose provided the opponent has sufficient chess pieces to checkmate your king.
If the opponent cannot checkmate by any series of legal moves, then the game is drawn. As per the standard FIDE rules, after making the first illegal move the player’s opponent is allotted two minutes extra time. While for the second illegal move the player loses the game.
An illegal move is any move that doesn’t follow the standard rules of chess. You can read more about it in my article: Illegal Moves In Chess: Everything You Need Know (With Examples)
Can You Move Yourself Into Checkmate?
You can’t move into check or checkmate because that violates the standard chess rules. However, you can make a move that allows your opponent to check or checkmate you.
Whether you put your king in check or checkmate intentionally or accidentally, it is considered an illegal move.
In short, you can remember like this: Any move that puts your king into check is not allowed. Recall this statement every time you make a move to prevent making mistakes.
So that’s it! Hope you found this post helpful. Now below I have shared the answers to some of the related frequently asked questions which you can read to clear your doubts. Till then Thanks, and Good Luck!
