Any hints on this one?

 

 

 

@duckDecoy  Think about where the 9 needs to go in column 9

R7C9 and R9C9 could take a 9     Is there some reason to rule one of those out?

If it has to go in one of those two, what does that then eliminate in box 9?

I'd love to know how to make the next step on this one

@duckDecoy - focus on column 9.  There are a couple of cells in there that are constrained to only 2 options.  The wrong one in either of those very quickly locks things up.

Thanks @floydbloke.  Ive never before tried the "pick an option and see if it results in a contradiction" technique before, you've added a new tool to my arsenal.
