Hi dan:
Very smarts comments you have made to probe your point, but maybe there is
another angle to see this issue about the meaning of champion of anything. The
clue, I suppose, is the difference between to be proclaimed champion in a
determinate event and to be the very best. The first thing happens in a singular
event, like to play the final game in the soccer championship or to win or lose
against Deep Blue in an specific match of only half a dozen games. But also when
we talk of a champion we are not just makinfg reference to the guy that got the
cup, but just to the performer that in average has a better perfomance than the
competence. In this last sense statisc results are the core of the matter and
surely the statistics asociated to human beings are so good or bad to that than
the statistics asociated with chess computers. We tend to forget that when we
clasify a chess player as GM or IM we are not saying that he got a title of such
kind in this or that tournament, BUT that he has such rating and title after
hundred, perhaps thousands of games.
Anothet things we forget -it seems to me Smir forgot it - is that strenght is
something very different to relative force, such as that measured by Elo
ratings. Strenght could be and surely is permanent, as Amir say, but not so the
rating because thais last one depends of a relation of forces with changeable
oponents. It is not matter of you changing your strenght, but also how the
oposition change yours. That's the reason computers that in the middle of the
80's had a 2000 elo now appear with a very much degraded one; they now compete
with a lot stronger programs.
Cheers
Fernando
