Yes, as long as it doesn't put him in check.
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.
The king can move one square in any direction. If it moves into a square that is occupied by another piece, it takes that piece only if the king is not endangered if it gets next to it in order to capture it.
Yes, as long as the move doesn't leave the King in Check from another source.
The king can take another piece anytime, but it is not smart to do so until perhaps the last moves of the game, if at all.
The King is not allowed to be in check. If a piece is on a square where if the King were there, the King would in check, the King isn't allowed to capture it.
You can't checkmate another king unless the king is the only piece left on the board.
Yes.
Yes, it can, as long as it doesn't put the king in check. PS, it's "capture", not "kill".
Yes, in fact if you're trapped you can move the top piece of the king with another piece.
Placing a checker on top of the checker being "kinged" is what it takes to turn an ordinary checker piece into a king. One piece represents the ordinary playing piece. One piece on top of another represents the king.
The capture of the King is the penultimate goal in the game of chess .
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.
