In chess, the king is not allowed to move or attack diagonally. The king can only move one square in any direction, including horizontally, vertically, and diagonally. Additionally, the king cannot move to a square that is under attack by an opponent's piece.
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.
Yes , and your opponent must counter the move .
Yes, your king is able to capture other pieces only if they are unprotected by your opponent.
No, because before you kill the king, but you're about to after your opponent's turn, they must get out of check because your queen is checking the king. In other words, they must use their own chess pieces to block the queen or they can move the king into a different spot that is not checked.
a king can move backward
he can move only one square per turn, but he can go backward
If what you mean by "leaving your king open" is not moving it out of check if your opponent puts your king in check, then yes, that is an illegal move. If your king is in check you mustmove to protect it. If you mean simply that you leave your king in the center of the board without castling or other protection, then it is not an illegal move. It may (and probably will) result in your king coming under attack very quickly, however.
In chess, a checkmate move is a move that one makes that puts the opponent in a position where the king piece has nowhere to move.
The object of the game of chess is to capture your opponent's king. Being as his king resides on the opposite end of the board your must move forward toward that point in the effort. ----------------------------------------------------------------------- It is important to note that during the attempt to capture or checkmate your opponent's king you may move many pieces to many areas on the board forward or back toward your own side of the board. The pawns move forward except when they capture another piece by moving one space diagonally. Some pieces move only forward and backward on the board in a straight line. Rooks move like this as many spaces as they are able in a straight line. Some pieces move only diagonally across the board. Bishops move only diagonally as many spaces as possible. Queens and kings are capable of moving in any direction. The queen moving as many spaces as she desires and the king limited to one space at a time. Knights move all over the board but do it in an "L" shape.
A pawn can kill dianguly foward or backward and move only 1 space at a time. (or two at the first move of the pawn)
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).
