Thanks for the puzzle immp!
After basics: Code: | +----------------+-------------+-------------------+
| 1 35 4 | 23 8 57 | 2357 9 6 |
| 239 6 2579 | 23 4 1 | 2357 8 2357 |
| a23 8 257 | 9 6 57 | b12357 c1257 4 |
+----------------+-------------+-------------------+
| 57 4 3 | 1 2 6 | 8 57 9 |
| 57 2 1 | 8 9 4 | 6 3 57 |
| 6 9 8 | 5 7 3 | 4 d12 e12 |
+----------------+-------------+-------------------+
| 8 35 59 | 4 1 2 | 379 6 37 |
| 29-3 7 29 | 6 5 8 | 139 4 f13 |
| 4 1 6 | 7 3 9 | 25 25 8 |
+----------------+-------------+-------------------+
|
Then I used the following chain: 3r3c1 = (3-1)r3c7 = r3c8 - r6c8 = r6c9 - (1=3)r8c9 => r8c1 <> 3; stte. |

Almost like dongrave
(3)r7c2 = r7c79 - (3=1)r8c9 - r8c7 = (1-3)r3c7 = (3)r3c1 => - 3r1c2,r8c1; stte |
