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.
