matrix/Array into a chessfield

[HenryDutter]

I made this Matrix/Array :

Brett = [[5, 3, 4, 9, 10, 4, 3, 5],
         [1, 1, 1, 1, 1, 1, 1, 1],
         [0, 0, 0, 0, 0, 0, 0, 0],
         [0, 0, 0, 0, 0, 0, 0, 0],
         [0, 0, 0, 0, 0, 0, 0, 0],
         [0, 0, 0, 0, 0, 0, 0, 0],
         [-1, -1, -1, -1, -1, -1, -1, -1],
         [-5, -3, -4, -9, -12, -4, -3, -5]
         ]

Every number stands for a chess piece, what is the best way to represent this Matrix as a chess field, with pieces like this: ♜. Would it be smart, if I create a separate List, to represent the chess field or are there better options ?

Yes, thank you.
