Hello Uri,
Well I'm not sure of the exact difference in rating that gives you "zero" rating
points.  What I was saying was that in trying to keep the rating under 1800
(1600-1800) many 1300 players (meaning in the 1300-1400 range)played it and
raised the rating up so when a 1700 player played and lost it went over.  I did
not stop 1800 players from playing it.  I was trying to find a setting which
kept it in the 1600-1800 range and the lower rated players made it difficult.
Also several people will play the machine and resign early.  I think they are
"sandbagging" for what reason I don't know.  Maybe there are prizes in some of
the tournaments held on ICC.  I never entered one.   That free account was very
busy.  There are very few computer accounts in the 1600-1800 range and mostly
people rated below that are playing the computer trying to raise their ratings I
guess.  It was an experiment that failed because ICC did not give me enough
leeway / time to find the right settings.  This was mostly due to the fact that
the rating numbers in Fritz are so far off from ICC/blitz.
