Code:

.---------------------.---------------------.---------------------.
| 6 *49 7 |*15-9 2 *145 | 8 3 45 |
| 39 5 *3489 | 89 6 *348 | 7 1 2 |
| 2 348 1 | 578 478 34578 | 9 6 45 |
:---------------------+---------------------+---------------------:
| 1 489 2489 | 258 489 458 | 3 7 6 |
| 7 6 24 | 12 3 *14 | 5 8 9 |
| 5 389 389 | 78 789 6 | 4 2 1 |
:---------------------+---------------------+---------------------:
| 4 7 56 | 36 58 2 | 1 9 38 |
| 8 1 56 | 36 57 9 | 2 4 37 |
| 39 2 39 | 4 1 78 | 6 5 78 |
'---------------------'---------------------'---------------------'

(9=4)r1c2 - (4)r2c3 = (4)r2c6 - (4=1)r5c6 - (1)r1c6 = (1)r1c4; r1c4 <> 9

leaves xy-wing {489} to finish it off.
