Kraken cell (268)r2c2
(2)r2c2 - r2c8 = r7c8 - r7c4 = r9c5 - (2=6)r1456c5 - r2c56 = r2c23 - r13c1 = (6)r7c1
(6)r2c2 - r13c1 = (6)r7c1
(8)r2c2 - (8=6)r2c6
=> -6 r7c6; stte

Another way using the same (long...) first chain:
Almost kite: (6)r2,c1 + rfr2c5
[kite(6)r2c6*=r2c23-r13c1=r7c1]
(6)r2c5 - (6=2)r2c26 - r2c8 = r7c8 - r7c4 = r9c5 - (2=6)r1456c5 - r2c56 = r2c23 - r13c1 = (6)r7c1
=> -6 r7c6; stte

Nice work, Cenoman! You found all the tough chains!

I can only add one extra digit to your second chain...
(6)r2c23 - r13c1 = (6)r7c1.
Along with your final long chain one then gets a finned 1-Fish r2\c6 + rfr2c235 => -6 r7c6.
And, further add the covered base cell (6)r2c6 for Kraken row (6)r2 => -6 r7c6.
