There's got to be a one-stepper in there, but I couldn't find it. Coloring on 8; AD are pincers; r6c6<>8. That exposes an XY-Wing on 238, pivoted in r6c6 which sets r2c5<>8.

Code:

|  6   C128 5  | 248 14  9    | 3  27 78 |
|  9    4   3  | 5   28  7    | 28 6  1  |
| D128 C128 7  | 6   13  23-8 | 4  59 59 |

Your cells plus r2c5 and r5c5 leads to r6c1<>8, with any value in r6c6.
