If someone wants to call me out on my last step, feel free. I just realized that if r3c6=5, then r2c9can't be=7.

Try this Marty:
(2=9)7n1 - (9r8c1=2r3c13)AUL178:r358c13 => r1c1 <> 2.

SV,
Thank you, but I don't understand the notation. I thought I made another post which seems to have disappeared.
It was 2r3c13=9r8c1-(9=2)r7c1=>r1c1<>2.

That's exactly the same as my chain but just written in reverse order, so you've got it!
AUL178:r358c13 just describes the potential deadly pattern, candidates 178, location r358c13. The 7n1 at the start is alternate language for the cell in row 7 column 1. (2=9)7n1 has exactly the same meaning as (2=9)r7c1.
