I used an XY-chain to anchoured at r7c2 & r3c3 to eliminate 9 at r7c3.

Starting at r7c2 up c2, across r5, down c7, across r9, up c8, across r3 to r3c3.

Thanks for the puzzle immp! After basics:

Code:
+---------------+---------------+---------------+
|  1   6    2   | 458  58   3   |  7    9   489 |
| d45  7    3   | 4568 9    56  |  1    2   458 |
| d459 8   e59  | 7    1    2   |  6    4-5 3   |
+---------------+---------------+---------------+
| c259 3    4   | 58   2568 1   | b89   7   256 |
|  8   59   6   | 3    25   7   |  49   1   245 |
| c25  1    7   | 9    2568 4   |  3   a58  256 |
+---------------+---------------+---------------+
|  6   59   159 | 15   4    8   |  2    3   7   |
|  3   4    8   | 2    7    9   |  5    6   1   |
|  7   2    15  | 156  3    56  |  48   48  9   |
+---------------+---------------+---------------+

Then I used the chain (5=8)r6c8-(8=9)r4c7-(9=2|5)r46c1-5r23c1=r3c3 => r3c8 != 5; stte.
