I can see a path of W-wing twice, finned x-wing, x-wing and xy-wing.
I see lots longer but no big fish (that I saw) to cut through the chum.

Code:
9 . .|3 7 6|. . .
. 4 3|. . .|. 9 .
. . .|. . .|5 . .
-----+-----+-----
4 . .|2 . 3|1 . .
8 3 .|. 6 .|. 2 5
. . 6|7 . 5|. . 8
-----+-----+-----
. . 4|. . .|. . .
. 1 .|. . .|2 8 .
. . .|1 3 4|. . 6

in this mug pattern on 49, either the pair {1,2}r236c5 is true, or if not then the 7 is true in r5c7

1...(9=7)r9c7 - MUG49[(7)r5c7 = (12)r236c5] - (2=9)r7c5; r7c9 <> 9
2...x-wing 9
3...(2)r1c9 = (2)r2c9 - (2)r2c5 = (2)r3c6 - (2=7)r7c6 - (7)r8c6 = (7)r8c3 - (7=5)r4c3 - (5)r4c2 = (5)r1c2; r1c2 <> 2
4...extended w-wing... (1=2)r1c3 - (2)r1c9 = (2)r2c9 - (2=1)r2c5 - (1)r3c6 = (1)r5c6; r5c3 <> 1
