Kinda messy but it works - a 3-stepper:
1.X-wing on 8 in c38 setting r1c38<>8
2.457 XYZ-wing pivot at r1c3 setting r1c1<>4
3.a type 3 (?) UR in 45 in c35.Either r1c3 or r3c3 must be <5> setting r1c3 and r3c3<>4. |

As kuskey pointed out, this was a messy one. After the XYZ wing, you can do to X wings on 1 and 7. this reduces the UR to a type 1 ..... Not that it matters .... A UR is a UR!

I agree. It was kinda messy for me. After the X wing on 8 and the XYZ 457 . I looked at r1c1 If 7 then r2c7 =7 or if 8 then r3c8=8 and after further elementary work in box 9 r2c7 becomes 7 again So r2c7 =7. After solving it was quite tricky remembering what the key moves were. Thus after the XYZ r5c1 = 4 but this leads no further (for me), and I don't like Urs
As I predicted above I had forgotten an earlier (not very useful) XY wing 247 that removes the 4 fromr7c8 allowing the easy analysis in box 9 referred to above! |

The "official" route seems to be X wing on 8 XYZ 457 leading to x wing on 7.
then two xy wings on 247 to remove both 4 and 2 fromr7c8! |

Thanks George! I totally missed the the second XY 247 wing.

| I am relieved to read the comments above! I've just solved this one and thought I was making an absolute dog's breakfast of it. As it happened I went down the X wing, XYZ wing, XY wing path - but is was hard going and took me over 30 minutes to get through it. Glad to see I wasn't the only one who found this puzzle 'messy'. |

I guess I just don't get it!
Everyone here is complaining about how messy the solution to the puzzle was and that it was hard going and took over 30 minutes to get through it.
Get a life! It was a puzzle! You got 30 minutes of challenge out of it! Geesh... |

I don't view the comments as complaints. Most of these puzzles are easy one-steppers, so this one was somewhat of an anomaly. |

| I certainly wasn't complaining. I enjoy a challenging puzzle. It was just that on this occasion, I thought I was blind to the obvious (which often happens!). As it turned out, I was not alone. Phew - alzheimers hasn't hit yet. |

After basics: | Code: | +----------------+----------------+----------------+
| 478 1 4578 | 9 45 6 | 3 2478 248 |
| 2 9 47 | 3 8 1 | 47 6 5 |
| 6 3 458 | 2 45 7 | 9 48 1 |
+----------------+----------------+----------------+
| 17 5 6 | 4 17 2 | 8 9 3 |
| 147 8 147 | 16 3 9 | 27 5 26 |
| 3 2 9 | 8 67 5 | 1 47 46 |
+----------------+----------------+----------------+
| 5 7 3 | 16 169 8 | 24 124 249 |
| 9 4 18 | 5 2 3 | 6 18 7 |
| 18 6 2 | 7 19 4 | 5 3 89 |
+----------------+----------------+----------------+ |
It took me six steps: X 8, XYZ -459, XY 2-47, X 1, X 7, XY -247, though I ignored the UR.

I know this is not normally needed for these puzzles but an m-wing solves it in one step.
| Code: | | m-wing(27) (2=7)r5c7 - r6c8=(7-2)r1c8=r7c8 ; r7c7<>2 |

Nice!
But, isn't that kind of like bringing a gun to a knife fight?

I'd say it was only a minor escalation in weaponry! Sort of BB/Air gun level 
You could argue that, from a chain perspective, wsml- wings are simpler than xy-wings - same number of strong links but only involving two candidates. (I'm not really going to argue that...)
For me I generally do a better job of spotting m-wings than xyz-wings for sure! |

Now this is the kind of puzzle that I like. I like multiple steps in a puzzle, it makes it a lot more fun.  |

Bringing a baseball bat to a pillow fight? 
I agree, much more fun, and much more interesting, than this site's usual VH, which is: XY, thank you ma'am.. |
