First, a finned x-wing (3)r48c35; r8c6<>3=6

This results in the following code with a BUG+4 condition with two polyvalued cells in b1.
Code:
 *--------------------------------------------------*
 | 4    7    6    | 3    8    1    | 2    9    5    |
 | 9    3    15   | 7    45   2    | 8    14   6    |
 | 2    158  158  | 6    45   9    | 7    3    14   |
 |----------------+----------------+----------------|
 | 5    2    39   | 1    39   4    | 6    7    8    |
 | 13   19   7    | 28   6    38   | 5    24   49   |
 | 8    6    4    | 5    29   7    | 3    12   19   |
 |----------------+----------------+----------------|
 | 6    4    2    | 9    7    5    | 1    8    3    |
 | 7    18   138  | 4    13   6    | 9    5    2    |
 | 13   59   59   | 28   123  38   | 4    6    7    |
 *--------------------------------------------------*


Following the procedure provided recently by RonK, I concluded that r8c3=1, or r9c5=3, or r3c2=1, or finally that r3c3=5

BUG+4; r3c5<>5
(1)r8c3-r9c1=r5c1-(1=9)r5c2-(9=4)r5c9-r3c9=r2c8-(4=5)r2c5;
(3)r9c5-(3=9)r4c5-r4c3=r5c2-(9=4)r5c9-r3c9=r2c8-(4=5)r2c5;
(1)r3c2-(1=9)r5c2-(9=4)r5c9-r3c9=r2c8-(4=5)r2c5;
(5)r3c3;
