The Usurper
(Published on 15. April 2024, 02:09 by KMD)
Hello, Kennet's Dad here. This puzzle began two years ago, and not until recently, having improved as a solver and setter, was I able to bring the puzzle to this, deleting a lot of unnecessary clues and rules along the way. Let me know how you fare in the comments.
Rules:
- Every row and column must include the digits 1-9 once each.
- All cages must sum to the same total; digits may not repeat in cages.
- Digits a king's move apart in chess must not contain the same digit.
I have a YouTube channel where I discuss and analyze literature and poetry. And please consider a free subscription to my novel.
Solution code: row 3 followed by row 6, left to right, no spaces

The difficulty spike was around this point, approximately halfway through (imgur.com/a/LMC3cli) where I proved that r9c9 was in r8c123, as r9c9 plus twice C isn't fifteen. Then its position in column six revealed that r3c1 wasn't A. This is probably not intended though?
Your puzzle title reminds me of this cute comic on tumblr (tumblr.com/ayy-junipei/760496213510553600)

Probably the hardest puzzle I've personally solved, but includes some really lovely logic. Glad I stuck through to the end.
