The Bishop is a great chess piece. It has a unique way of moving and is important for all chess players to use.
The Bishop moves only on diagonals. For younger children who are not familiar with diagonals I would describe this as on squares of matching color.
When setting up the board the bishops go next to the King and Queen. For white this is c1 and f1 and for black this is c8 and f8. You will notice when setting up the board that you have on bishop on a white square and one a black square. Throughout the game this should stay constant (unless there is a pawn promotion into a bishop) and you know if you have two bishops on a white or black square there was an illegal move made. Bishops in chess attack the same way they move and cannot skip over pieces.
