Not much harder than a VH, but needing different techniques. I used 3 non-basic moves.

coloring on 1,3,and 4.
Plus an xy-wing to finish it off.

I usually look for all coloring eliminations and not just x-wings even for the vh-s on this site, so this was pretty much a "regular vh" for me, nothing like deadly patterns or Medusas

Unlike nataraj, I didn't spend any time (probably should have) looking for coloring, but searched in vain for wings. There were three ERs, after which I started Medusa and a wrap appeared quickly which solved the puzzle.

In other words, I solved it the same way that I've solved puzzles rated 130 points lower. Wink

I found the coloring on 4 was key to find the xy-wing
