Yes, if the king is in check, the next move must take the king out of check. You do not necessarily have to move the king, you could take the attacking piece, or block the check by moving a piece in the way.
Yes. If you have your opponents king under threat, you have to say check. If you have their king in a position to take it and they have no move left to save it, you say checkmate.No, you don't have to say check or checkmate. I used to play in USCF tournaments and we never did.
No, except for when the only way to get out of check is to capture the piece that is attacking your king.
Yes, but only if that results in you not being in check anymore. For instance, if it is the one that is checking you. When your king is in check, your only option is to stop the king from being taken. Otherwise, the game is over and you've lost. There are three ways to stop the king from being taken: move the king out of check; block the piece that has attacked the king; or -- here's the answer to your question -- capture the piece that has attacked the king. Any of your pieces that is able to do so, including the king itself, may capture the attacking piece.
A King in Chess may take any other piece except another King. The reason is that in order for a king to take another king, the first king would have to move adjacent to the other king, which is an illegal move.
Nothing, if the king was knocked over inadvertently. The laying down of a player's king has come to symbolize that player conceding victory to the other player. It is symbolic only and has no meaning unless intended as a symbolic gesture of concession.
Yes, any piece can take a queen. The only time a King could do it is to get himself out of the queen's check.
A king can take a piece in chess when it is in a position to capture an opponent's piece by moving to a square that is occupied by that piece.
Yes. The only way is to move a piece so that it blocks your king from check and checks or attacks another piece of the opponent. Another way is for the king itself to attack the piece that is attacking it. Example is if the queen foolishly moves adjacent to the king without being protected by another piece, the king may capture the queen. It is not limited to simply moving out of check.
Depends by which rules and standards you are going by. Some say no and if you take another piece to get out of check-mate then it was technically just check, other rules state that its check-mate if all other avenues of movement are blocked and the only way out of check-mate is to take the piece then yes it is possible.
Yes, in a game of chess, the king can put the queen in check if the queen is in a position where it can be captured on the next move.
You don't take/kill a king in chess. You have to put it into checkmate, ie, there are no moves the opponent can make with any piece, to take the king out of check. When this happens, the game is over.
