It'll solve with W-Wings on 26 or 68 or UR 28 in boxes 89. Probably can also use the same UR as a 26 or 68.

Remote pairs (86-26) eliminates the 8 in r8c1 and solves the puzzle.

Marty, I also played around with the possible UR combinations 26,28,68 in boxes 8 & 9, but did not get a deletion that completed the puzzle.

For UR 26, I used pincers (6) in r8c8 & r9c4; r9c9<>6 plus transport; r7c5<>6
For UR 28, I used pincers (8 ) in r8c8 & r9c5; r9c9<>8 plus transport; r7c5<>8
These two steps result in r7c2, r9c9=2 but to not complete the puzzle.

I did not get any deletions for UR68.

What was you solution for UR28?

Ted, a brief check indicates I probably screwed up. No time to check it in detail today.
