Every page is also served as markdown at its URL plus .md. The king moves one square in any direction or castles, may never be left in check or moved into check, and is never captured. The king moves one square in any direction or castles, may never be left in check or moved into check, and is never captured, because the game ends when it is checkmated. A king has three jobs. First, it must stay safe: the Laws say a player may never leave their own king under attack or expose it to attack, so every move you consider is limited by what it does to your king. Second, it moves slowly, one step to any adjoining [square](https://georgelichess.com/glossary/square.md), with one special case, [castling](https://georgelichess.com/glossary/castling.md), in which the king travels two squares towards a rook and the rook jumps to the square the king crossed. Third, it ends the game. A king in check must be saved at once, and a king with no legal escape is checkmated, so a trapped king decides everything else on the board. The Laws also forbid capturing the king, which is why play stops at mate and never reaches a [capture](https://georgelichess.com/glossary/capture.md). One consequence is that the two kings can never stand on neighboring squares, since each would attack the other's square. Its role changes with the phase of the game. Early on it hides behind pawns, usually after castling. Once most pieces are traded it leaves cover and fights as a piece of its own, heading for the center and escorting pawns. In English notation it is K, and it starts on e1 for White and e8 for Black. Before any move, count which squares around your king are safe. Also worth reading is [Queenside castling](https://georgelichess.com/glossary/queenside-castling.md). Queenside castling is a move in which the king steps two squares toward the a-file rook and that rook jumps over to the square the king crossed, written 0-0-0 or O-O-O in notation. A neighboring idea is [Kingside castling](https://georgelichess.com/glossary/kingside-castling.md). Kingside castling is a move in which the king steps two squares toward the h-file rook and that rook jumps to the square the king crossed, written 0-0 or O-O in notation.
