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.
