The main goal of playing chess is to capture the enemy king in a checkmate. What this means is that the king will need to be carefully guarded at all times during the game. The king can also be moved in certain ways to avoid getting caught in a checkmate. The king can move along files, ranks, and diagonals, except one square. The king will not be able to make a move that will put it under enemy attack, and cannot move to a square next to the enemy king. Teach your kids all this and more with this worksheet.
