I found 5 steps as follows:
Quote:
An "underground" skyscraper on <5>,
Type 4 UR24,
coloring on <2>,
w-wing25 which provided a deletion and then transported both pincers to get a second deletion,
and a xy-wing245 with pivot <24> at r9c2.

Do I get the "Brass Ring" Question

I liked the 25 W-wing followed by a 256 xy-wing. This simplifies into a BUG, although there is a 5-cell xy-chain if you don't like BUGs.
