To illustrate a valid solution, here is a first non-optimized at all solution of value 79
Let us fill a Peaceful Weighted Sudoku Grid with the maximum value with Chess pieces with the following rules:
- The grid must contain a full set of chess pieces: both colors must have exactly one King, and at least one Queen, two Rooks, two Knights, two Bishops, and eight Pawns.
- Neither side may be in checkmate.
- No row, column, diagonal, or box may be completely filled.
- No row, column, or box may contain two of the same piece of the same color, except pawns.
- Each row, column, and box must contain at least one pawn of each color.
- No diagonal may contain two Queens or Bishops of the same color.
Scoring
- Every time a Queen appears you score 8 points
- Every time a Rook appears you score 5 points
- Every time a Bishop appears you score 3.3 points
- Every time a Knight appears you score 2.7 points
- Every time a Pawn appears you score 1 point
What is the maximum score you can reach? :D
Notes: there is no promotions for the pawns and you choose whether Blacks attack towards the north or if it is Whites :)
