An x-wing, then a skyscraper (-7's) will finish it off.

I did a multi-coloring on 6, which I think wasn't a factor, then a Type 4 UR on 15 solved it.

The possible [24] UR* in R56C19 eliminates <7> in R7C7, three possible ways to avoid the DP(Deadly Pattern)

A. R56C1=|9| => R5C2=|4| => R7C2=|7|

B. R5C9={7} => R5C8={9} => R5C2={4} => R7C2={7}

C. R6C9=<8> => R4C7=<9> => R9C7=<4> => R3C7=<7>

I found a x-wing at r28c59 that removed <6> @ r28c6 (which may not have been useful), but a xy-wing with pivot @ r7c7 and pincers @ r1c7 & r8c8 deleted the 8 at r1c8 which broke the puzzle open.

A single XY wing was enough for me: 678 pivot R7C7.

Ted,

Yes, that 15 UR is also Type 3 and eliminates the <7> as you have noted.

This VH has an XY as a possible first move (as proved by putting the resulting 5 in r1c8) in draw/play which then grades the reulting puzzle as easy!
