1. (2=7)r9c7 - (7=492)r8c349 => -2 r8c78, r9c5
2. (7=52)r5c49 - (2=491)r8c348 - r5c8 = (13)r45c7 => -7 r45c7; lclste
... or 1. Kraken row (2)r8c4578

Nice finding, this DP(49)r8c348
I propose a simplification of your first chain:
(1)r8c8 - (1)r5c8 = (13-7)r45c7 = (7-5)r5c9

I like this too ! With the same use of AHS r45c7, and 7r45c7 as a target, the AIC in your second post becomes:
(7=2)r9c7 - (2*)r8c8 = [(13)r45c7 = r5c8 - (1=*492)r8c348 - (2=57)r5c49] => -7 r45c7; lclste
