I eschewed the UR, though I don't think it would help much. (So far I have only done this once, with pencil & paper.)

Dan,

I can't find your solution path. I used the UR, 2 Skyscrapers and ended up with a BUG+1.

I had a different two-stepper.

1) A W-Wing on 27

2) An XY-Wing Chain on 374. The chain was 34-37-37-37-47. The pincers took out the 4 from r1c8, finishing it off.

since no one pointed it out yet, the useless skyscraper on 3's see's the {3,7} cells and makes the 7's pincers in r8c2 and r6c6, this eliminates the 7 in r8c6. then that combined with the skyscraper on 7, which is also present, finishes it.

Actually I did it in no-steps and was gonna quote that Irving Berlin song:
"Anything you eschew - I can do better"
But I guess it's back to the drawing board.
