Uncovering the king and it's exposure to check is an illegal move .
Depends if you want to lose the game or not. If you don't, then move the king!
Yes, the king may capture the piece that is checking it.Yes, but only if that piece is on a square adjoining him, as a king has mobility of only one square per move.
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.
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.
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. In addition to moving the King, check can be escaped by capturing the checking piece or blocking its path. Of course a Knight cannot be blocked, so that option is not available in that case. Also note that the King cannot avoid check by "castling".
The objective of chess is to checkmate the king, where the king is in check by a piece and it cannot block the check, move to another square, or capture the piece checking the king.
If the king is not currently in check and has nowhere to move without being in check, it is stalemate, which is a draw. However if any other piece of his can make a move (i.e a pawn), then it is not stalemate, and you are forced to move whatever piece can be moved.
Yes, the king can move out of check, provided that doing so is a legal move (i.e. does not move into check again). If it cannot and there is no other way to defend the check, then it is mate.
For example the king is under check from a bishop. The player with the king in check decides to move a piece to block the bishop. After that piece steps into the line between the king and the bishop, that piece cannot move until either the bishop moves to a different location or the king moves to a different location.
The goal in chess, or the object of the game, is to checkmate your opponent's king. A king is in checkmate when he is attacked and no matter what move he attempts to make he is still being attacked (or in check). There are three ways to get out of check: move the king to a safe square, capture the checking piece, or block with another piece. If a player is in check and cannot get out of check, he is in checkmate and has lost the game.
No , if your king is in check you can not counter with placing your opponent's king in check - you must respond to the move on your next turn by dealing with your king in check by moving the king out of check , removing the attacking piece by capture or by blocking the checking piece or you will need to concede / resign from the game .
