This should be a fun puzzle if you don't over-think it. Still, one or two bumps in the road.
| Code: | +-----------------------+
| 6 . 7 | . 9 . | . . 2 |
| . 2 . | . . . | 8 . 6 |
| 5 . . | 1 . 2 | . . . |

For no particular reason, I seemed to look at bivalue techniques on this puzzle, with one exception. I used six steps to complete it.
| Quote: | | x-wing <4>, Type 4 UR<15>, Type 4 UR diagonal <58>, finned xy-wing <458> with fin <7> at r2c5, xy-wing <568> and another xy-wing <168> |
Another very fun puzzle!
