ANTI-KNIGHT: Cells a knight's move apart cannot contain the same digit.
KROPKI: Cells separated by a white dot are consecutive. All the white dots are given.
Otherwise standard Sudoku rules apply.
Solution code: row 9

Love your puzzles and got used to this ruleset, which I really enjoy. I loved the conceptual consequences of the negative constraint on kropki dots together with the shading!

I stared for a few minutes, trying to wrap my head around this. Then once I figured it out, the puzzle went very fast, and was quite easy. Enjoyed it, thanks!

Rules clarifications
1) Standard k-dots are always orthogonal. However, diagonal K-variants exist, and cannot therefore be assumed to NOT exist. There are multiple instances of diagonal adjacencies here.
2) Adding a k-dot will make the puzzle easier. Adding "k-dots apply only in boxes" will not.

FIXED MISSING KROPKI (OOPS!)

My apologies, the grid is missing a second kropki. As TimoTheDude noted it is between R3C1 and R4C1.
I’ll fix it as soon as I have something more than my phone.
Apologies to all, and thanks to those that pointed my error out.

So for anyone that gets stuck solving this, there is another white dot between R3C1 and R4C1
---You are absolutely correct. It is fixed now. Thanks. ---ATK

I triple-checked it. There is a dot missing if you apply the rules.
The puzzle works if the Kropki rule would be: "Consecutive cells WITHIN THEIR BOX are seperated by a white dot. All white dots are given."
---Damn! Good catch! Fixed now. Thanks for everything.---ATK
No need to thank me. I enjoy your puzzles very much. Still working to complete them all.

The Puzzle solves nice and easy. The logic is great.
The Puzzle is because of the negative constraint on the easier side, but still fun.

A bit easier than usual with the negative constraint. But as always very enjoyable and a logical solve. Thanks for setting ATK.
