You have a standard chess board, and as many queens as you need. What is the most queens that you can put on the board so that no two queens can attack each other? What is the formation to put them in?

Keep in mind that a chess board has 64 squares (8x8), and queens can go diagonal, up and down, and left and right.

The idea is to place as many queens so that no queen is currently, without any further positioning, attacking any other. And color doesn't count. Geometrically this just means as many queens as will fit on the board so that no two queens are in the same row or column or diagonal straight line.
