Marty,

That's exactly how I did it. On further investigation, there are (at least) three W-wings lurking in the "after basics" grid.

I had three steps.

Quote:
w-wing 79,
An AIC found looking for xy-wings: (5=9)r3c6 - (9=4)r1c4 - r79c4 = r9c6 - (4=2)r9c9 - (2=5)r8c9; r3c9<>5,
BUG+3 forces r3c6=5.
