I take that back. I must have made a solving mistake, since I only needed one XY-wing.

I think you were right the first time, at least for me it was easier. Last week I needed Medusa and, in fact, in the thread, I verbed Medusa after learning about Calvin and Hobbes.

However, this week two W-Wings involving the same numbers in different cells were enough.

UR {4,6} doesn't really help
w-wing on {2,9} is nice

Needed an UR and a 5-cell xy-chain to complete this one. The <46> UR* in R35C46 eliminates both <6>'s in R3C46 (x-wing on <4> in the 46 UR), then a 5-cell

xy-chain(ABCDE) with pincer ends at R9C4(A) and R7C2(E) eliminating <2> in R7C4.

The second time I did it, using the computer to check for mistakes, I came up with two different W-wings on <29> that solve <9> in R8, and you are done.
