place the 3 black pawns and 7 white pawns to add to the appropriate numbers?

My guess would be black/white corresponds to lat/long? (or vice versa)

Something to think about: chess notation is 1-8 and a-f., with a1 on the bottom left and h8 on the upper right.

If we use chess notation, could that give us a lat/long using the special instructions from the last puzzle?

or maybe position the white rooks and black rooks in their spots to remove those numbers from the board?
