Interesting. Only one freebie at the start and a very busy grid, including at least one 8-candidate cell. But a quad in c9 got things rolling and I ended up basically with the same three steps as Dan. But in addition to the Remote Pairs, it could also have been done in the form of a kite or a simple coloring chain. I forgot to look at the time, but after I finished I was wondering if the grid was a BUG+1 as well.

I guess there wasn't a BUG+1. A Kite on 7 emanating from box 8 will do it and a four-cell coloring chain on 7 from r1c5-r1c8-r7c8-r7c6 will do it it too. There are other ways of doing the same thing as well.

I had a slight variation on the theme.

UR 24,
RP37,
Type 6 UR57 deleted 7 r9c2,
simple four cell xy chain deleted 3 from r8c9.

Hidden Pair exposes a <24> UR Type 1, <37> Remote Pair, turbot fish, ending with a <26> UR Type 1.

Wendy: I lump 2-String Kite, Skyscraper, Empty Rectangle, and finned/Sashimi X-Wing in with the basic turbot fish.
