Hello all,
It seemed to me that this puzzle had a little bit of everything along the advanced trail (depending on one's path). I will be interested in seeing what some of our astute community solvers come up with for a potential path. I needed at least 6 steps....main thing is...enjoy the puzzle.

Code:

| . 9 7 | 2 . . | 8 . . |
| . . 3 | . . . | . 1 . |
| 6 . . | 8 . . | . 7 5 |
+-------+-------+-------+
| 4 . . | . . . | . . . |
| . 1 . | 4 3 5 | . 8 . |
| . . . | . . . | . . 9 |
+-------+-------+-------+
| 7 2 . | . . 1 | . . 8 |
| . 5 . | . . . | 7 . . |

One step after basics.
If R9C5=8 =>contradiction R3C5=Ø
8R9C5-(8=1)R9C1-1R1C1=1R1C5-1R3C5;
8R9C5-8R9C1=8R6C1-8R6C56;
8R9C5-8R4C5=(8-9)R4C6=9R2C6-9R3C5=> R3C5=Ø=>R9C5=2=>solution.
Ciao a Tutti
Paolo
