Thanks Immp and Merry Christmas to you !
I will leave after basics to others and white out my solution. Decided on a less conventional one.
| Quote: | It's the march of the <28> pairs. Quite a few on the grid after basics and many can be linked.
What's interesting is being able to link the <28> pincer pairs in r5c9 with r8c1. The whole "bridge" consists only of six <28> pairs. What is nice is that they toggle each other so that if r5c9 is 2 then r9c1 must be 8 and of course vice versa.
This means a double elimination of 2 and 8 at r5c1 leaving only 7 in that square and stte. |
[Corrected x 2 - Diolch Tomos !]

Very similar solution, started off with a <14> UR to then leave with a lot of <28>'s
But I think you mean r5c1 in your post!
Merry Christmas to all |

| I did mean r5c1! Not r1c5. Too much Christmas cheer I suspect! The UR also comes first. |

No problem, I found that r5c1<> 2 and this solves it, but didn't notice that it could also be not 8
