Go up one level in this thread


It makes sense to me that Elo could predict that at a 200 point difference the
stronger player would win 75% of the time.   (Think about it:  Elo can predict a
200 point differnce because that is how the players got to be 200 points higher
... they win 75% of the time against players who are 200 points lower.  But why
on earth does that mean that a player rated 400 points higher would lose 5% of
the time?  One conclusion does not necessarily back up the other.)

The classic way to raise your rating on ICC is called "inching."  You play
lower rated players and get 1 point here, 2 points there, another point from
someone else.
