A little something until the next Very Hard shows up here. An interesting puzzle from BrainBashers that didn't (as usual) require a UR before the puzzle to fall apart.
It opened up with either a skyscraper or a finned x-wing for me.
| Code: |
+-------+-------+-------+
| 9 . . | . . 1 | . . . |
| . 8 2 | 5 . 7 | . . . |

Thanks,
Nice puzzle. Needless to say there is a UR in there (4,9) but for me an XY wing followed by a skyscraper did the job.
Where was the finned x-wing ? |

This is a very interesting puzzle!
I run out of basic moves at this point:
| Code: | +----------------+----------------+----------------+
| 9 457 47 | 3 2 1 | 6 458 58 |
| 46 8 2 | 5 46 7 | 1 9 3 |
| 1456 3 146 | 9 8 46 | 2 45 7 |
+----------------+----------------+----------------+
| 7 6 3 | 4 1 9 | 5 28 28 |
| 14 149 5 | 8 7 2 | 3 6 49 |
| 24 249 8 | 6 5 3 | 7 1 49 |
+----------------+----------------+----------------+
| 3 245 9 | 7 46 456 | 8 25 1 |
| 256 257 67 | 1 9 8 | 4 3 25 |
| 8 145 14 | 2 3 45 | 9 7 6 |
+----------------+----------------+----------------+ |
What next? There is a UR, an XY wing and at least one XYZ wing.
I find that these interact, one destroys the other. Depending on which you choose, the puzzle may be solved, or it gets harder!

For me at this point Keith, I pays me money and takes me choice.
You can either go:
1)Skyscraper on 5's which effectively finishes the puzzle off
OR
2)Go with the XY wing (see below)
Which takes a bit longer if you ignore the skyscraper........ |
