Play this puzzle online at the Daily Sudoku site

As well as Clement's: XY-Wing 12-5 pivoted in r6c7; r4c7<>5; also stte
I think a 29 W wing also makes the same elimination but I guess
I've reached the end of my attention span.....

I think the 125 wing only works if you apply the x wing in 2 as well!

Hi George, maybe I'm wrong but after applying Hugh's 125 wing I was able to solve it with just basics because of the lone 5 in column 7 and after that, everything fell into place. Am I missing something?

No, the wing solves it.
