Since it is unfortunately impossible to construct a true anti-queen sudoku, I decided to settle for as close as I could get to one for this puzzle.
Rules: All standard sudoku rules apply. Additionally 7 out of the 9 digits follow an anti-queen constraint, meaning that two of the same digit cannot be a queen's move apart if they are one of those 7 digits. The remaining 2 digits follow an anti-king constraint, meaning they cannot be a king's move apart. It is your job to find which digits follow which constraints.
Solution code: The 2nd row followed by the 8th row

@SudokuExplorer how did you manage that?! that is impossible on a normal sudoku grid. Did you use a different size grid or irregular regions? Either way I am very interested as to what you will post if you managed to do that.

Beautiful logic!
Btw if you are interested, tomorrow I will post a puzzle where all digits are queens. It turns out to be quite a restrictive constraint.

Love the logic! Great puzzle
