Urgh! A VH solved by an X wing.
X-Wing on 7 c67 -7r8c6 r8c8=3 stte
Also another much less interesting UR than Marty's 17 r34 r6c2=7 stte

I joined this site 12 years ago. At that time the puzzles could be solved by X-Wing as the only non-basic move. We complained to Sam (the owner) and it was a thrilling development when he made the puzzles slightly more difficult by adding the XY and XYZ-Wings.
