A system for determining the skill of a player eliminates the element of
chance by comparing players who have the same initial position. In the
case of cards, the initial position is the hand dealt to the player and
in tile games, it is the initial distribution and arrangement of tiles. A
player with a less than advantageous initial position may win a game over
an opponent having a better initial position. It cannot conclusively be
said whether this win is due to the good play of the winner or the bad
play of the loser. However, it can clearly be said that the winning
player has a higher skill level than the losing player.
