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

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!
