| I used two x-wings on <2> and that was it. I don't see any UR Type 1, XY-Wing, Empty Rectangle, Skyscraper, UR Type 2, or XYZ-Wing. |

| I looked again and found another x-wing on 5. Then it was three xy wings and another x-wing on 3 to finish it. I usually find Ers without too much trouble but didnt see them here (maybe they were there with the x-wings) |
