Queen Square (Posted on 2004-09-20) Difficulty: 3 of 5
What is the largest square you can paint onto a chess board such that you can still place five queens all on unpainted squares where all 64 squares are attacked?

Gamer does mean all 64 squares are attacked,

1 solution is:-
Queens placed on A2, B1, F8, G7 & H6.

This leaves a space in the middle of 5x5 squares ready for painting.

I think there are a lot more solutions than this.
