Place two pawns in the middle of the chessboard, one at $Q 4$ and the other at $K 5.$ Now, place the remaining fourteen pawns (sixteen in all) so that no three shall be in a straight line in any possible direction.
Note that I purposely do not say queens, because by the words "any possible direction" I go beyond attacks on diagonals. The pawns must be regarded as mere points in space — at the centers of the squares. See dotted lines in the case of The Eight Queens
