If a move is made which attacks the opposing king, that king is said to be 'in check'.
The player whose king is checked must make a move to remove the check.
The options are: moving the king, capturing the threatening piece, or moving another piece between the threatening piece and the king.
If the player whose king is in danger cannot do any of these things, it is checkmate, and the player loses the game.
