Ken's Puzzle of the Week

Attacking a Chessboard

- Place as few pieces as possible on a chessboard from an entire set of 16
white chess pieces, to occupy or attack the entire board. You do not
need to attack squares occupied by pieces. White is attacking up the
board (important only for pawn placement.)
- Place one of each type of chess piece (white king, queen, rook, knight,
bishop, and pawn) on a chessboard to occupy or attack the greatest number of
squares.
- Place one of each color of each type of chess piece onto a chessboard (6
white and 6 black: king, queen, rook, knight, bishop, and pawn), such that
no piece is under attack from the opposite color, and the greatest number of
unoccupied squares are under attack.
