Knight Vision Plus

My second go at a fog puzzle and the 9x9 follow-up to my first one, Knight Vision .
I hope you enjoy solving!
RULES:
- Normal sudoku rules apply.
- Anti-Knight: Cells that are a chess knight's move apart must not contain the same digit.
- Arrows: Digits along an arrow must sum to the digit in the circled cell of that arrow.
- Kropki dots: Black dots separate cells with digits in a 1:2 ratio. White dots separate cells with consecutive digits. Not all dots are given.
- Fog: The grid is partially covered with fog. Correctly placed digits will clear the fog around that cell. No guessing is required.
Solution code: Row 9

Dude this was fantastic. Felt more like 2-2.5 stars. Going to check out your first fogger now!

Took a little bit to find that "sneaky" deduction you mentioned (which is not difficult logic, just have to be looking in the right spot), but aside from that everything flowed very nicely.

I liked it, was one time i had to spot a specific clash that took quite some time but it didnt really require bifurcation. About a 2.5.

after completing the opening phase (about 35 digits, plus about the same number of candidate-marked cells, any continuation is buried so far down in the bifurcation chains that difficulty 2 looks wrong.

Thank you for your feedback. I can assure you that there is no deep bifurcation needed, but I definitely underestimated the difficulty of this one. About halfway through, there is one "easy" deduction needed to progress, but it's very random and sneaky... The puzzle should probably be 3 stars.
