This is a typical BrainBusters VH type puzzle. My two steps were:
Quote:
swordfish on 4 in r169c238,
xy-wing 26-4 with pivot 26 in r8c3 plus transport of pincer in r8c4 to r7c9 via r7c4.

A one-stepper is a 2-46 XYZ-wing in B78.

Otherwise there are an X-wing and a Swordfish to be found.

Thank you! I notice that the BB solution is X-wing, Swordfish, XY-wing. The XY-wing is actually the remnant of my XYZ-wing, making the critical elimination of <4> in R8C1.
