Here's the original puzzle:

+-------+-------+-------+
| 6 5 . | . . . | . 1 . |
| . . . | . . 8 | . . 7 |
| . . 1 | 4 6 . | 5 . . |
+-------+-------+-------+
| 9 . 5 | 8 . . | . . . |
| 3 . 2 | . 4 . | 7 . 9 |
| . . . | . . 1 | 4 . 5 |
+-------+-------+-------+
| . . 9 | . 2 7 | 3 . . |
| 1 . . | 9 . . | . . . |
| . 2 . | . . . | . 7 1 |
+-------+-------+-------+

And, here's how far I got using all the techniques I know:

+-------------------+------------+------------------+
| 6 5 4 | 7 3 9 | 28 1 28 |
| 2 9 3 | 5 1 8 | 6 4 7 |
| 78 78 1 | 4 6 2 | 5 9 3 |
+-------------------+------------+------------------+
| 9 4 5 | 8 7 3 | 1 26 26 |
| 3 1 2 | 6 4 5 | 7 8 9 |
| 78 678 68 | 2 9 1 | 4 3 5 |
+-------------------+------------+------------------+
| 45 68 9 | 1 2 7 | 3 56 468 |
| 1 3 7 | 9 58 46 | 28 256 2468 |
| 45 2 68 | 3 58 46 | 9 7 1 |
+-------------------+------------+------------------+

Can you please tell me what additional techniques I need to use in order to complete the puzzle? Thanks!

Thank you so much! I've never heard of that technique - it looks like it's going to be really helpful.
