The first diagram shows the basic checkmate position with a rook, which can occur on any edge of the board. The black king can be on any square on the edge of the board, the white king is in opposition to it, and the rook can check from any square on the rank or file (assuming that it can not be captured).
Micronutrients are the vitamins and minerals found in food that nourish your body and help keep you healthy. They are essential to your overall health. Choosing foods each day that are rich in vitamins and minerals is the best way your body is getting what it needs to be healthy. However, research consistently finds that most Americans have diets that lack an appropriate amount of vitamins and minerals.
