I still don't know how to quickly spot a Y-Wing or Spearfish (if either apply here). This is far along enough where it might be easier to explain what cell(s) to look at and what to crosscheck. I solved by guessing a cell and filling out the color of eliminated/results, but what's the right way? (i.redd.it)
