If there is a w-wing on 48 then that confuses me further about w-wings. I thought that w-wings (on a 48 ) had an 48-b-c-48 connection with a strong link comprising the b-c link. I am not seeing that here.
On the other hand, I see a kite. There is a stong link of 8 in row 4 and in column 7. This would remove the 8 in c8r6.
