Puzzle # 8: Anti-knight Sudoku!
Hello again! Another week down, and another sudoku variant yet to be seen here! I quite like Anti-knight Sudoku as it leads to some very nice logic, some of which is straightforward, but some of which is also quite tricky. I also like the aesthetics of how anti-knight puzzles can be put together, though this is my 2nd attempt at an Anti-knight Sudoku; my 1st attempt led to what is surely my most difficult puzzle yet ... more on that later, but for now, enjoy this offering!
Rules:
- Apply classic sudoku rules
- Identical digits must not be a chess knight's move apart, as demonstrated in the below figure

Enjoy, and may the cookie crumble in your favour!
