Puzzle rules
Normal Sudoku rules apply.
Orthogonally adjacent cells may not be consecutive. Cells separated by a knight's move or a king's move in chess must be different. A black dot separates cells with a ratio 1:2. Not all dots are given.

Very satisfying once the initial "aha!" kicked in. Love going from a totally blank grid to suddenly everything making sense.

@farodin64 It can be done without using the box 3 dot. I've done it myself, but had to do long chain eliminations. The box 3 dot helps neatly with a solve path I found. But if there is a good solve without the box 3 dot, kudos for finding it. The secret Yawnus knows makes a huge difference, but that has to be shown first (in my way of thinking about a solve) and that is not trivial.

Nice puzzle, thanks for the fun! Btw my solve was w/o using the black dot in box 3. May be it can shorten the flow somewhere.
Just getting used to the fact that I can reply to comments by editing them. I couldn't find a nice solve-path with just three dots, though I did find solutions without either c2 or c7 (so two three-dot puzzles). If there is a clean solve without one of the dots, then well done for finding it. The way I do it the c7 dot has a part to play.
Thanks so much also for the feedback - this was my first puzzle on LMD, and I am learning fast (though perhaps not quite quickly enough)

@Yawnus. Thanks for the information. I have been discovering for myself how powerful these constraints are, and have noticed some things. I think I will move on to disambiguating non-consecutive, or non-consecutive anti-knight grids as there is some logic I wanted to showcase which was constrained away when I explored the Miracle options. I have put up another Miracle puzzle which disambiguates rather differently. The Kropki method I want and the XV method in the other (Dead Roman Miracle) would both work for non-consecutive puzzles, but I want constraints to avoid (if possible) given digits. I will keep looking. Meanwhile this was fun to explore on holiday.

This set of constraints, popularized by Mitchell Lee's Miracle Sudoku, is really powerful. There are unique solutions for two given digits, two Kropki dots, a single arrow or killer cage, for example. Most of those are very difficult for humans to solve, unless you know the secret of this ruleset (in a hidden comment).

Very nice! Not as hard as I thought it would be.

loved it from beginning to end - even if it took me way over an hour!

Nice miracle variant. Thank you!

I think this solves with only three dots - either of the singles can be deleted. But that required lots of bifurcation. I think there is a decent human solve possible with the extra dot.
