A king is checkmated, when the player whose turn it is to move is in check, and cannot move to avoid the check. The consequence of this is that all pieces of this player are removed from the board. When one of the players has been mated, the player that gave the mate gets a bonus. This is the player that was the last to give check to the mated king. There is a stalemate position, when the player whose turn it is cannot make a legal move, without being in check.
