Either a Classic:
| Quote: | | 568 XY-Wing pivot r7c7 |
or a 'dubious': | Quote: | | type 1 UR on 49 in boxes 4 and 5 |
sets this one in one step.

Another one step but also equally dubious solution:
| Quote: | | type 1 UR on 26 in boxes 6 and 9 |
I hope I did the fancy hidden solution correctly, thank you Hugh for your great posts.

Hugh What is the meaning of dubious? |
Some say, and I do not count myself amongst their number, that
URs are somewhat lesser solutions compared with wings, fish, chains
etc. Thus the quote marks round the word.....
