1r9c4=(1-5)r8c4=(5-6)r8c5=r2c5-(6=1)r2c7 => -1r9c7, pair to the end
To avoid the pair:
(1=4)r1c358-(4=2)r9c5-(2=1)r9c7-1r9c4=(1-5)r8c4=(5-6)r8c5=r2c5-(6=1)r2c7-(1=2)r9c7-(2=4)r9c5-(4=1)r1c358 => 1r1c3,-1r9c7

I only found lclste solutions. I am interested by Eleven's chain that goes through the same cells (r9c5 & r9c7) twice (in opposite directions). I have always limited myself to using a cell only once in a chain (although in overlapping ALSs I would use a cell twice). Something new to learn ever day!

I'll sometimes do this just to avoid posting a "proof by contradiction". Interesting how we have an aversion to that.
