I calculate a different number. For a rating difference of 2800 points, I calculate the average points expected in one game for the weaker player as: p = 0.5*erfc(rating_difference/400.) 2.0919128E-23 So, you should never lose and not allow one single draw in over 2e22 games. Good luck! :-) I guess, Dann used some approximate formula, that will only work well with rather moderate rating difference. Regards, Dieter
