Leren,
I'm sure I don't know all there is to know about W-Wings, but I thought you would've had to prove the 3 in r3c4. Obviously you have a nice solution, but I don't recognize it as a W-Wing the way I understand that technique.

Marty, this was a new one on me, too, but you can see that it's valid if you look at it a bit. The paired 3's in r2c23 strong link to the single 3 in r2c5 just as well as a single one would have, so it works just like a more conventional W-wing. Dang clever.
Marty R. wrote:That's another one of my "senior moments." My comments don't make any sense. It's a perfectly normal W-Wing with a grouped strong link. I made my comments as if it were an M-Wing. Maybe I got confused because M is an upside-down W.

You're better than me! . I'd never heard of a grouped W-wing before.
