Colours of Chess

After my previous chess-sudoku hybrid puzzle I thought I would make a chess-themed puzzle that requires a lot less chess knowledge and is generally just more approachable.
Hope you enjoy!
Play the sudoku here:
Rules:
Normal Sudoku rules apply.
Digits on grey lines form palindromes (they read the same forwards and backwards).
Each digit represents a chess piece, with the following counts across the grid:
2 Kings, 3 Bishops, 3 Knights, 1 Rook.
A digit may not be able to capture another instance of the same digit using its assigned piece’s standard chess move (e.g. two occurences of the SAME “knight” digit cannot be a knight’s move apart). The presence of other digits/pieces does not block or interfere with these capturing relationships.
In this puzzle, the Rook is boring so it may NOT appear on palindrome lines.
Arrows outside the grid indicates the sum of the digits along the diagonal in the arrow’s direction.
Any feedback is welcomed!
Solution code: Row 1

So I think it's explained but I just didn't understand, the chess piece designation of a digit only applies to THAT digit, right? It's not like all 3 knight piece digits cannot be a knight's move from each other. Right?
Reply" Yes it only applies to its OWN digit. I made a small tweak to the rules, hopefully it is more clear now.
