Don't know where everyone is this morning- perhaps everyone had given
up waiting for a VH?
After basics:

Play this puzzle online at the Daily Sudoku site
Two solutions- there may be more (Select box to view)
Quote: | A 'double' 125 XY-wing pivoted at r7c7 or r7c9 is a one step solution.
Pretty much the same numbers can be used for a 25 W-Wing which
also does it in 1 |

I also used the XY-Wing (12-5) pivoted in r6c7. There's also one pivoted in r5c9 but I don't see any pivoted in either r7c7 or r7c9. |

My mistake Marty- so shocked at being the first to post at 9.13 I confused
the pivots with the positions of the numbers 'solved' by the xy-wings...... |
