				| Yes, XY (59-2). 
 I'm unable to follow along with the W-Wing. I can see as strong link in c7 but the two 69s that it connects don't see a common cell for an elimination.

				| Hello all... 
 Marty, the 69 r2c9 and the 69 r4c7 have the strong link on 6. Therefore r123c7<>9.

				| Hi immpy, 
 even as Marty I don't see the strong link with number 6.
