				| 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:

 | 349 47 5   | 1  3479 8   | 6  37  2  |
 +------------+-------------+-----------+

				| 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. |  |
