Which position could you have 9 queens and control the least amount of squares on the board?

I'd imagine there are many positions where you control almost all squares like this one

 

But assume I was playing around trying to get 9 queens in the first place and didn't want to stalemate. What would be the best way to make sure the queens don't take up all the squares?

Something like this ... over 20 available squares.
