				I've always been able to solve puzzles on this site with wings (X, XY and XYZ). But I am stuck on today's at this point:
 
 
 	  | Code: | 	 		  
 
+---------------+-------------+------------+
 
| 39   4   2389 | 123 123 6   | 18  7 5    |
 
| 35   258 238  | 7   123 9   | 18  4 6    |
 
| 6    7   1    | 4   5   8   | 3   2 9    |
 
+---------------+-------------+------------+
 
| 1    58  68   | 28  4   257 | 267 9 3    |
 
| 2    9   48   | 38  6   37  | 47  5 1    |
 
| 7    3   456  | 25  9   1   | 246 8 24   |
 
+---------------+-------------+------------+
 
| 34   1   7    | 9   238 23  | 5   6 248  |
 
| 8    6   259  | 125 127 4   | 29  3 27   |
 
| 3459 25  239  | 6   378 235 | 249 1 2478 |
 
+---------------+-------------+------------+

Does this puzzle require some other technique or have I just lost it? If the latter, please break the news to me gently    
 
 
Cheers |

				You have missed a hidden pair, not too important, and an xy-wing. (Important.)   |

As one who doesn't see hidden pairs, I see them as their complementary subsets, in this case a naked quint.
 
 
As to the XY-Wing, I had three candidates in the pivot cell but it worked as an XYZ-Wing for a one-step solution. |

				| I did not use the hidden pair/naked quint, but an x-wing (5) r68c34, which opened an xy-wing 58-28-25 in boxes 4 and 5. |

				Thank you all. Obviously my brain was still numb during this morning's cuppa. A fresh look now after a day of 'cut and thrust' in the office and the XY wing leapt off the page.

				| Used an x and xy wing but it took a while. I'm still a bit shaken up by traumatic events of past week.  My daughter married an American ! |

You reared her, so look in the mirror for the blame.    |
