There is an X-Wing which looks like all that's needed. I used a Kite and got two uses from a W-Wing: once with a direct elimination and again with pincer transport. This was my position after basics:

Code:

+------------+-------------+-----------+
| 5   2  467 | 3  4789 149 | 89 17  46 |
| 467 9  8   | 5  2    14  | 37 137 46 |
| 1   3  47  | 79 4789 6   | 89 2   5  |
+------------+-------------+-----------+
| 38  78 1   | 6  37   2   | 4  5   9  |
| 2   6  349 | 79 5    349 | 37 8   1  |
| 349 47 5   | 1  3479 8   | 6  37  2  |
+------------+-------------+-----------+
| 367 1  367 | 2  369  39  | 5  4   8  |
| 489 5  49  | 48 1    7   | 2  6   3  |
| 36  48 2   | 48 36   5   | 1  9   7  |
+------------+-------------+-----------+

My grid, after basics, is the same as Marty's.

There is a Type-4 UR <89>.

Ther are two X-wings on <3>: In R49 and C36. Remarkably, they do not make the same eliminations.

There is a W-wing <47> which takes out <4> in R5C3.

The clear and present x-wings on <3> do it in.
