It certainly had some variety, although I don't know that all my moves were necessary. I took my usual scattershot approach and used:

Quote:
Two W-Wings, plus pincer coloring on the 2nd one, hidden UR, Type 1 UR, multi-coloring, simple coloring and finished it with an XY-Wing with pincer coloring. Alternatively, it could have been finished with a BUG+1.

Marty, you seemed to have a very long ride with this puzzle.

My solution was very similar to Norm's sequence:
x-wing on <3>
xy on <234>
Type 1 UR <19>
Bug+1

I don't mind the long rides, I enjoy using a variety of techniques. A possible reason for the long ride might be that both you and Norm used an X-Wing early on. I hate looking for them and do so only as a last resort, so I used everything else I could see and didn't have to resort to them.

I don't explicitly look for x-wings. but seem to notice them when I am looking at strong links for single digit patterns like skyscrapers, kites, and coloring. The pattern that I do last is ERs; I seem to spend a lot of time with minimal results.
