And a very 'ho hum' solution indeed. What makes the puzzle a bit
more interesting are two W-Wings - one on 49s that doesn't do it in one
and the one on 19s which sets r3c3 to 2 and does the business.

Whilst the 49 W wing does not give an instant resolution it sets up a BUG +1 in block A that does!

While the 49 W-Wing doesn't finish it by itself, adding a pincer transport does. The wing makes a direct elimination of -9r1c1. A transport from r9c1 to r5c2=> -9r1c2 which finishes it.
