Safety from the Queen II (Posted on 2004-03-30)

I had read about a sequel to Safety from the Queen.

Is it possible to put 8 queens on the board so that 11 squares are left unattacked?

Put the queens at c2, c1, d1, g3, g2, h3, h2, and h1, leaves a7, a6, a5, b6, b5, b4, e8, e7, f8, f7, f6 unattacked.
