Or:
Kraken cell [269]r8c3 => -9 r5c8 using segments of the same chains above.

Same as Steve's:
9r6c7 = r6c3 - 9r8c3 = (XY-Wing (26)r8c3,(16)r3c3,(12)r8c3) - (1=9)r3c8 => r3c7<>9,r5c8<>9; stte
(with the extra digit in the pivot cell, being true in the solution)

I found this Almost, Almost xy-wing(56-2) while chasing the seemingly non-related AUR(24)r45c16 and could not resist pursuing it............
AAXY-wing(56-2) with pivot (56=4)r7c2 and pincers (26)r7c5 & (25=6)r9c3 => r9c5<>2
xy-wing(56-2) => r9c5<>2
||
4r7c2-4r7c3=(4-1)r2c3=1r2c7-(1=9)r3c8-9r5c8=9r5c2-(9=5)r6c3-5r79c3=5r7c2 Contradiction => r7c2<>4 [Marked "a....i"]
||
6r9c3-6r3c3=6r3c7-r78c7=6r9c9 Contradiction => r9c3<>6 [Marked "w....z"]
