 The Quaker Queens of Chess (Posted on 2003-06-03)
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.

 Submitted by Jonathan Waltz Rating: 3.3333 (6 votes) Solution: (Hide) There can obviously not be more than 8 queens on the chessboard - since there are only 8 rows, the ninth queen would find all the rows "occupied". Charlie has shown here that having 8 is indeed possible. Therefore, the maximum number is 8.
