Beats me.

Marty, how did you even get this far?
When I start from the givens, I have a kite and an xy-wing, but how did you get rid of 79 in r1c7, 7 in r1c9, and those 8s in col 6 box 8?



This is where I stand:

Not sure of the specifics. I had one ER on 8, Medusa which just trapped a couple of numbers which didn't do much, what Scanraid would call a Hidden UR on 13 and a Finned X-Wing on 7.
