A chess board has been broken into 4 pieces and offset into a Sudoku grid.

Given digits represent the starting position of a single chess piece.

1, 2 = Black and White Rooks, respectively. There are 2 of each color

3, 4 = Black and White Knights, respectively. There are 2 of each color

5,6 = Black and White Kings, respectively. There is one of each color.

7,8 = Black and White Queens, respectively. There is one of each color.

9 = 2 Bishops, The Dark square bishop is a black piece, the white square bishop is a white piece.

Rules:

Normal Sudoku rules apply.

“Move” the chess pieces around the board, leaving its number in each square as you go.

Every chess piece on the chessboard moves along the chessboard as if the chessboard was put together properly (not offset). E.g. A rook on R3C4 could move to R2C6, not to R3C6

Kings numbers have a “Kings Move” Restriction. They can be anywhere, except immediately next to their same number in any direction on the chessboard, not necessarily the sudoku board. Rooks, Knights, Queens, and Bishops each follow their normal chess move rules. All pieces ‘jump’ over other pieces to valid squares (obviously).

Every given chess piece must make at least 2 valid moves. Pieces may, and often will, move more times.

Every instance of every number that appears on the chess board must be from a continuation of moves from the given starting positions.

No two pieces will ever use the same square or use a square more than once

Squares off the chessboard only have regular Sudoku restrictions

At the puzzles conclusion, the chessboard will contain exactly 32 white pieces and 32 black pieces.
