It is startling to have so few unsolved cells and yet have difficulty.
A most excellent puzzle, thanks Dan! |

Basics got me to here:
| Code: |
| 6 5 39 | 7 4 1 | 39 2 8 |
| 1 4 8 | 9 2 3 | 5 6 7 |
| 39 7 2 | 8 6 5 | 139 34 14 |
|-------------------+-------------------+-------------------|
| 2 9 6 | 5 8 7 | 4 1 3 |
| 8 1 4 | 3 9 2 | 6 7 5 |
| 7 3 5 | 4 1 6 | 2 8 9 |
|-------------------+-------------------+-------------------|
| 35 2 137 | 6 37 9 | 8 345 14 |
| 4 6 37 | 1 5 8 | 37 9 2 |
| 359 8 1379 | 2 37 4 | 137 35 6 | |
Then a x-wing<3> creates a w-wing<17> with strong link <7> in row<8>. The <1> in r7c3 is transported to r3c9 via r7c9 to delete <1> from r3c7 and finish off the puzzle.

| It's always possible (probable?) that I did something wrong, but the X-Wing was all I needed. |
