I always forget to check for those BUG Lites. Embarassed
Code:
+---------+---------------+----------+
| 3 179 8 | 6    C59  B15 | 2  4  17 |
| 5 19  2 | 4     7   A18 | 6  89 3  |
| 4 17  6 | 2-89 E389  23 | 17 89 5  |
+---------+---------------+----------+
| 9 6   1 | 58    4    58 | 3  7  2  |
| 7 4   3 | 12    16   26 | 9  5  8  |
| 2 8   5 | 79   D39   37 | 4  1  6  |
+---------+---------------+----------+
| 1 3   9 | 78    68   67 | 5  2  4  |
| 8 5   4 | 3     2    9  | 17 6  17 |
| 6 2   7 | 15    15   4  | 8  3  9  |
+---------+---------------+----------+


R2c6=1--->r3c5=8; r3c4<>8.

Or BUG+3; all possibilities lead to r6c5=3.

I found it surprising that in a grid like this with so many bivalues that I couldn't find one of the conventional wings.
