Each chess piece has a point value.
The following is an example of an average point count:
King = 0 (Kings cannot be counted in points)
Pawn = 1 point
Bishop = 3 points
Knight = 3 points
Rook = 5 points
Queen = 9 points
Points are counted simply to determine who has an advantage during a chess game.
Points may be counted in order to determine a winner if a game is being timed, and time has elapsed.
The player with the most points at the end of the time period, wins the game.
