HELP PLEASE

Modify the code so that there are twelve RED pieces, positioned on the black squares of the bottom three rows of the board.

Create a BlackGamePiece class, and add BLACK pieces to their appropriate starting positions (i.e. on the 12 black squares in the top 3 rows of the board).

Ensure that BLACK pieces move appropriately.
