PS: simpler ...
(2=7)r8c3 - (7=2356)r7c1368 => -2 r8c1, r9c23; stte

=> -2 r9c2, - 2 r9c3; stte
(Explanation: at least one of r7c68 must be not 6)

I made one chain to show the contradiction, not sure whether it's correct. :?

(2)r9c23 - (27=5)r78c3 - (5=6)r7c8 - (6=3)r7c6 - (3=257)r7c13,r8c3 - (2)r9c23 => -2 r9c2, - 2 r9c3; stte

No, not particularly.
I was happy to conflate my two chains then "Let the reader figure out that it's merely a chain being used to arrive at a conclusion."
Those end terms "(2)r9c23 -..." and "...- (2)r9c23" showed the contadiction.
It was sufficient for me to put a 2 in either r9c2 or r9c3 on the left hand side to see it would kill them on the right hand side.
Job done.
But it's good to see your AIC, perhaps I could have done that too if I'd had enough confidence that my single chain was accurate.

"& -27 r8c1"
Bonus points. :D
