An interesting one that was full of UR moves!
There is a straightforward Type-2 UR(14) which if played in the obvious ways leads to a colouring move to solve the puzzle.. however playing it as a strong link leads to an interesting one-stepper.

I used a half-dozen moves, more than I needed because I found some stuff that I missed after playing the moves.
Couple of W-Wings, couple of URs, a Finned X-Wing and Coloring on 1 to finish it off. |
