[dcwusjbb] Skill difference can be quantified

Chess is an interesting game because if you practice at it, you get better, a lot better.

How levels exist between the top and beginner?

Define two players to have a "one class difference" if the better player has an expected score of 2/3 of a point per game. How many class boundaries exist between the average complete beginner and the world's best?

How does the number of class boundaries in chess compare to the number in other popular games, for example go 囲碁?

The number of classes reflects the degree to which you can improve with practice. It represents how good the game is for humans.

This measure penalizes games for which draws are possible.
