Your puzzle seems to have multiple solutions. Are you happy that you have posted it right?:?:

It has 115 solutions, with the following common clues. At least one of the others is missing. On symmetry gounds, r9c4 looks like the culprit.
Code: Select all
Common clues (31):
  4  0  3  0  0  5  0  0  2
  8  0  7  0  0  0  0  5  0
  0  5  2  0  0  0  8  9  3
  5  0  0  0  9  8  0  0  0
  0  0  0  0  0  6  0  0  9
  0  0  0  0  4  7  0  0  5
  3  8  6  0  0  0  9  0  0
  0  2  0  0  0  0  5  0  8

Thank you.
I had all the candidates you wrote except for the '2' on row 8, column 2, how did you decide that it should be a '2' there.
Does what you wrote mean that it cannot be completed?

Pauline

The 115 solutions to the puzzle have these 31 cells in common, as determined by one of my utility programs. Whether it found the '2' by logic or brute force I don't know. The puzzle cannot be completed beyond that point. The puzzle as you have presented it is invalid, lacking at least one clue (possibly r9c4).
