The game is over when the king can not move and is in danger of being taken. Any piece could put a king in danger of being taken. Theoretically, a king is capable of capturing an opponent's king. However, the opponent's king would first have to have moved into check, which is an illegal move. Therefore, while a king can take a king, it can never happen.
But a king can participate in checkmating an opponent's king by contolling a square into which the opponent's king could otherwise move.
No, there is an exception. A king cannot directly threaten another king because they cannot ever share adjoining squares, or even any that meet at a corner. Only a queen, rook, bishop, knight or pawn can directly apply the attack resulting in checkmate (though a pair of them might collect the win in the case of double check that is checkmate).Chat with our AI personalities
Yes and no. If the king is in check then you are in the position to kill it but, the other player must move him out of check. If the king is in checkmate, then you have won the game and the other player can't move.
The King in Chess is actually one of the weakest pieces. Since it can only move one square at a time, it has a hard time getting out of the way of other attacks. The only piece weaker than the King is a Pawn, which (generally) can only move one space at a time, and only forward.
Except that a King can never "kill" (capture) another King, it can take any pawn or piece of the opponent. However, in doing so, it cannot be placed where an opposing piece could then attack it. When a king is attacked (check), it must be removed from attack: either by capturing the attacker, by moving, or by interposing another piece or pawn between the attacker and the king (this is not possible when attacked by a knight). When the King cannot be removed from attack, it is checkmate, and the game is over.
