It would be nice to see more discussion.
By the way, I have convinced myself to try solving hard puzzles the way you do, oaxen.

No basic at all in the beginning.
I tested "3" on row 1 and rather soon it was obvious that 3 shall be in R1C7 and in both cases a bunch of correct numbers show up.
After that just solve with ordinary basic techniques. So in a way, this Menneske was rather easy, sometimes one has to open secondary chains and the paper is full with intricate pencilmarks.  |
