Chess Pairs Sudoku

(Eingestellt am 31. Juli 2020, 15:46 Uhr von Genomico)

Apply classic sudoku rules. Additionally, two cells containing the same digit form a chess pair when they are a knight’s or a queen’s move away from each other. Each cell must be part of at least one chess pair.

So, give every cell a happy little friend :) Enjoy solving!

The puzzle is available online on Penpa and f-puzzles.

Lösungscode: Column 2 and Column 4 (without separators).

Warum wird die Dame bemüht, der Läufer (Bishop) tuts doch auch. zwei gleiche Zahlen können nicht in der gleichen Spalte bzw. Reihe stehen, also nur diagonal möglich, eben einen Läuferzug entfernt.

Answer: Yes, I could have said Bishop too instead of Queen. I used Queen because she's mentioned in other variants as well.
Actually a chess pair is formed when cells have a distance of any chess piece (King, Queen, Rook, Bishop, Knight or Pawn.), but some of them are of course not possible because of the classic sudoku rules.

Love the concept of reversing the normal chess move constraints. The final sets of 2/3s at the end was fun to work out as well.
