				| Oh dear!  Another VH that, by the definition we've been accepting for all these years, is not "very hard":  needs no wings. 
 But I found it a delightful "hard":  it needs a pair, a triple, and then another pair.  Before I found these, I'd made a terrific mess with all my "pencil marks".

				| Wow!  I thought I had screwed up again!  That's pretty unusual, isn't it Marty?  I've only been following this site for a couple of years but this seems pretty unusual to me. |  |

				| Don, it does happen from time to time. I don't know the frequency, but it's just enough so it's not a big surprise. If I knew anything about constructing puzzles, I'd have an understanding as to how it happens. I doubt that Sam INTENDS for it to happen occasionally. |  |

 Here is what I have on this puzzle.  I have spent quite a while trying to figure out how to solve this with no avail.  All the comments so far indicate that it is very simple.  Please tell me what I am missing.  Many thanks,  Jeff

				| I didn't think it was simple; it just didn't require any wings!  It's easy to miss.  You've got to look a little closer for locked candidates.

 Hey, by the way.  How did you eliminate the 9 from r7c9?
 I'm glad you printed this grid out because I was wondering if it was at around this point that the computer applied a VH move.
 Maybe the 379 XYZ Wing with pivot at r1c9?  But then again, maybe not since it doesn't appear to solve it.

				| I can't believe I missed the locked 9's in Box 7.  I eliminated the 9 from R7C9 using a 679 XYZ pivoted in R4C7. 
 Many thanks.  Jeff
