I used the color, but in a kite. Prior to that I played a Type 6 UR, probably just because it was there.

Two steps:
1) W-Wing <25>-2=2-<25> (strong link in 2 row 2) eliminaing 5 inr8c8 which leads to:
2) XY-wing <15>-<25>-<12> eliminaing 1 inr7c8 solving the puzzle.

I noticed a Sashimi x-wing on 8 prior to finishing basics and, just for fun, took the deletion; singles then completed the puzzle.

I then repeated the puzzle and completed basics; the Sashimi x-wing turned into a skyscraper.

he_ku_1971,

Welcome to the forum. If what you want to post is actual grids, take a look at the article on how to post aligned grids in the Site Help sub-forum.
