Kraken Cell (1279)r4c1:

r4c1
(1) - r7c1 = r7c2 - r2c2 = (1-3)r2c6 = r8c6 - r8c8 = (3-1)r9c8 = (1-7)r9c7 = (7-5)r2c7 = (5)r4c7
 ||
(2) - (2=7)r4c4 - r1c4 = (7-5)r3c5 = r2c5 - r2c7 = (5)r4c7
 ||
(7) - r8c1 = r8c9 - r2c9 = (7-5)r2c7 = (5)r4c7
 ||
(9)

=> -9 r4c7; stte

(Found by Hodoku, not me. Lots of other Kraken possibilities with the same hub cell as well. Anyone with something more interesting?)

My p&p steps:

1) AIC-Loop: (2)r5c7 = (2-8)r5c4 = (8-7)r1c4 = (7-5)r3c5 = r2c5 - r2c7 = (5-9)r4c7 = (9)r5c7 - loop
=> -2 r1c4, r4c5; -5 r2c289, -12 r4c7

2) AIC-Loop: (3)r2c5 = (3-1)r2c6 = r2c2 - (1=8)r7c2 - (8=3)r7c5 - loop
=> -28 r2c6, -1 r36c2, -8 r7c1, -3 r79c5

3) AIC: (8)r4c9 = (8-7)r2c9 = (7-5)r2c7 = (5)r4c7 => -5 r4c9
4) AIC: (3)r2c6 = r8c6 - r8c8 = (3-1)r9c8 = (1-5)r4c8 = r4c7 - r2c7 = (5)r2c5 => -3 r2c5
5) W-Wing: (9=2)r4c1 - r4c4 = r5c4 - (2=9)r5c7 => -9 r4c7, r5c3; stte

[Added: Post-analysis reveals that my second loop is actually irrelevant. Then again, loops are always fun! Speaking of which, my first loop would get two more direct eliminations as:

(2)r5c7 = r5c4 - (2=7)r4c4 - r6c5 = (7-5)r3c5 = r2c5 - r2c7 = (5-9)r4c7 = (9)r5c7 - loop
=> -2 r1c4, r6c56, r4c5; -5 r2c289, -12 r4c7]
