To use a board, you can create a Chessboard object using the Board() instantiator.

my_board = Board()

Boards have an instance variable for every square, which you can refer to, shown in the following block of code.

starting_king_square = my_board.e1

You can also refer to the entire board at once if you want to select everything with .board. The following code uses the Create animation to animate the entire board appearing at once.

self.play(Create(my_board.board))

You can create a piece object by calling their respective methods, and pass in the color to specify the pieces' color.

white_pawn = Pawn(WHITE)
black_bishop = Bishop(BLACK)
white_rook = Rook(WHITE)
black_queen = Queen(BLACK)
white_king = King(WHITE)
black_knight = Knight(BLACK)
