Two steps for me.

Either of two moves does the same thing: XY-Wing (467) with pincer transport or XY-Wing Chain (67-47-47-47-46) and then XY-Wing (562) with pincer transport

Marty,

I had the same first step, and then a remote pair.

I also had the same first step and then a Type 3 UR 67 in r29c56 that formed a subset 12 thereby deleting 2 from r6c6 to complete the puzzle.

Very interesting: three solutions each using the identical first step and each using a different second step.
