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?

Should the problem read "...where all 59 uncovered squares are attacked" or "...where all 64 squares are attacked" as the problem currently reads?  The latter seems hard, though I think I have an answer for the former.
