    i know this reference. the question is why the expected value is compared with the score of a player. really i can't understand the logic behind this.

    if I have a score higher than the expectation of my performance, you can infer I'm doing better than my early plays. then I should gain higher rank.

    yes i know this tale. the question is a little different. the expected score is the probability of win and half the probability of draw. and so question is why this probability is compared with the actual score?
