The problem is that you upstate New Yorkers obviously get up too early...
If you'd only wait for us lazy Birmingham (UK) solvers....

Yes, your XYZ (which I didn't see) is nicer than the 17-4 XY wing pivoted on
r3c5 -4r9c4

It's staying up late (1 am my time), not waking early. I could wait for you next time if you'd like.

I like your XY-Wing, especially the elimination because rather than solving a cell it leaves a pair, which is fun.

You're too kind. As well as compliments, we obviously complement each other
as all I saw was the -4 in r9c4 rather than in r1c5!

PS- Please don't wait for me...that could sometimes be interminable.
