Quicky - couldn't find an X, but a W-wing did it. Curious what others found.

My wife found an xy, but I solved it with no advanced techniques as all. In fact I told her that it must have been a mistake to classify it as a VH when it should have been marked Easy.

I also used a xy-wing with the pivot in b4.
This was another easy, one-stepper. It would be nice if the VH puzzles were more involved.

Fast going up to the <379> xy wing - which took me a while to locate, because I'm xy-wing challenged. Don't believe it can be done without a VH step.

Just to clarify, then:
Code: |
+-------------+-------+----------+
| 5 28 6 | 7 9 1 | 28 4 3 |
| 79 2379 379 | 8 4 6 | 29 1 5 |
| 1 89 4 | 5 2 3 | 89 67 67 |
+-------------+-------+----------+
| 47 37 1 | 6 5 8 | 34 9 2 |
| 2 6 8 | 4 3 9 | 7 5 1 |
| 49 5 39 | 1 7 2 | 6 38 48 |
+-------------+-------+----------+
| 8 79 579 | 2 1 4 | 35 36 69 |
| 3 4 2 | 9 6 5 | 1 78 78 |
| 6 1 59 | 3 8 7 | 45 2 49 |
+-------------+-------+----------+

Play this puzzle online
The XY indeed should have been pretty clear. The W-wing was based on the 79's in Blocks 1 and 7 and the 7's in Block 4.

I was playing around to see how many different moves I could find. The 79 W-Wing didn't get me very far, but the M-Wing on 49 in boxes 49 made it a one-stepper.
Also, to preclude the DP 28-29-89 in rows 123, columns 27, r2c2 must be 3 or 7. One of them led to an invalid solution and the other one solved the puzzle, but with less elegance. |

I kind of figured it would be pretty easy when I filled in boxes 2, 5, and 8 immediately! |
