Detective Chess Game

Detective Chess is a puzzle game based on the rules of Chess. Five pieces are placed on a chessboard - you are told what squares they are on, but not which one is on which square. There are some squares given with the numbers on it. These numbers represents number of pieces attacking that particular square. You have to deduce the position of each from the number of times certain squares are attacked. There's only one solution.
