This is the hardest 9-grid KK puzzle I've found. I have not solved it.

It may not be clear that cell (9,4) is given as 4.

 

The puzzle turns on whether 84x is 7-2-6 or 7-3-4, and I've run into dead ends both ways.

Nice.

I actually stayed up last night and got it.
I got the 7s in rows 234 ok.
I attacked row 1 by trying stuff for cells 7 and 8.
Once I made the right guess and CORRECTLY looking at the
consequences, the 1289 cells opened up as you said.
