All pieces on a small chessboard
by John from John D. Cook on (#6YM6J)
Here's another little chess puzzle by Martin Gardner, taken from this paper.
The task is to place all the pieces-king, queen, two bishops, two knights, and two rooks-on a 6 * 5 chessboard, with the requirement that the two bishops be on opposite colored squares and no piece is attacking another.
Here is a solution.
