Still another enjoyable VH or VH+ type puzzle. Six steps, of which one or two may not have directly contributed to the solution. In random order, I had an ER, x-wing, two URs, a xy-wing plus a transport and a w-wing.
Also had a significant amount of clean-up part way through.

(1)r4c2 = (1)r6c2 - (1)r6c5 = (1)r7c5 - (1)r7c9 = (1-8)r8c7 = (8)r6c7 - (8)r6c45 = (8)r4c6; r4c6 <> 1
w-wing {1,7} removes 1 from r5c6
singles finish. |

| I finished up with the same W-Wing as Norm, but had seven steps prior, including a rare (for me) XYZ Transport. Also a few ERs, M-, XYZ- and XY-Wing, as well as a UR as the first move. |
