come to think about it, its quite obviously wrong as if the queens are placed on a1, a2, b2, c2 and b1 quite a lot of spaces are not covered! perhaps 8 queens is much harder...
isn't the most amount of queens you can have on one board 9 because you can have one for each pawn and your orriginal queen. but this would nearly be impossible. because it depends what your opponent has on the board to protect them from your queens?
how do u get 8 queens on the board and have none of them intercepting each other?
