Am I wrong in thinking that this 'Hard' needs the X wing on 1 r38c35 to

Hi Hugh,
if you only want to use basics, you can see that in column 6, number 1 is only in sector 8; when you delete number 1 from r8c5 you can solve it with basics.

I thought it was just me Hugh. It's frustrating, isn't it? I've been looking at an old VH from the archive all day and I STILL don't see it! ugh... |
