I used a useless Type 1 UR on 28. Then simple coloring on 5, perhaps the same as Dan's skyscraper, but it didn't take me to the finish line, but it did expose a puzzle-ending W-Wing on 39. |

Similar to what Dan did: Code: | +----------------------+----------------------+----------------------+
| 2 1678 1678 | 4 9 135 | 138 38 5-67 |
| 679 1679 3 | 15a 8 2 | 4 56@ 5-67 |
| 4 18 5 | 6 13 7 | 1238 238 9 |
+----------------------+----------------------+----------------------+
| 8 23567c 267 | 135b 136 9 | 23 235-67 4 |
| 369 123569d 1269 | 8 7 4 | 239 235-6 56@ |
| 3679 4 679 | 2 36 35 | 389 35-678 1 |
+----------------------+----------------------+----------------------+
| 5 2389 289 | 139 4 6 | 7 19 28 |
| 379 28 4 | 1379 5 13 | 6 19 28 |
| 1 679 679 | 79 2 8 | 5 4 3 |
+----------------------+----------------------+----------------------+ |
The cells 56@ are a W-wing connected by the chain abcd on 5. Eliminating 6 as shown.

Nice find Keith.
Dan, I don't know if my grid was the same as yours, but my coloring took out the same 5 from r5c9. |
