Lots of possibilities? That's not good for my ego. Laughing I didn't see much. Normally I prefer not to use chains if there's something else. But I couldn't find any of the usual moves that I look for.

R1c2=4 proves r2c6=6; r2c2<>6.

Code:

+----------+--------------+------------+
| 47 46  3 | 127  257  8  | 9  257 126 |
| 78 68  9 | 1237 2357 16 | 4  257 126 |
| 5  2   1 | 79   4    69 | 3  78  68  |
+----------+--------------+------------+
| 48 348 5 | 19   6    19 | 28 238 7   |
| 9  7   6 | 5    38   2  | 1  4   38  |
| 1  38  2 | 378  378  4  | 5  6   9   |
+----------+--------------+------------+
| 6  9   7 | 4    1    5  | 28 238 238 |
| 2  5   8 | 6    9    3  | 7  1   4   |
| 3  1   4 | 28   28   7  | 6  9   5   |
+----------+--------------+------------+

Possiblities -- many 3sis wings and almost locked sets live out there. I chose this one.
Code:
 *-----------------------------------------------------------*
 | 47   d46    3     | 127   257   8     | 9     257  c126   |
 | 78    8-6   9     | 1237  2357 a16    | 4     257  b126   |
 | 5     2     1     | 79    4     69    | 3     78    68    |
 |-------------------+-------------------+-------------------|
 | 48    348   5     | 19    6     19    | 28    238   7     |
 | 9     7     6     | 5     38    2     | 1     4     38    |
 | 1     38    2     | 378   378   4     | 5     6     9     |
 |-------------------+-------------------+-------------------|
 | 6     9     7     | 4     1     5     | 28    238   238   |
 | 2     5     8     | 6     9     3     | 7     1     4     |
 | 3     1     4     | 28    28    7     | 6     9     5     |
 *-----------------------------------------------------------*
 m-wing
 (6=1)r2c6-r2c9=(1-6)r1c9=6r1c2 => -6r2c2

either r2c6 = 6 or r1c2 = 6
