IMO, this is why we play the games and why we don't just crown the person with
the highest rating the champion before the event. If engine A beats engine B,
even though engine B might be stronger if we played a few thousand games, engine
A deserves to win.

I think a lot of people forget that the rules are established before the event,
and that you win by being the best player within those rules. For instance
consider those reality T.V. shows where they stick a dozen or so people on an
island and vote one person off each week, and the last remaining person wins a
million dollars or something. There are only a handful of rules (don't
physically harm someone, and you can't conspire to share the prize with another
participant). Other than that, there are no rules. Inevitably, one participant
is considered to be a poor sport by the end of the show (they lied to a lot of
people, for instance), and people think that person doesn't deserve to win. I
disagree. I think that person simply played the game smarter than the others. He
or she recognized that there were no rules, while others did not. It is the same
with any sport. If a football team wins a tournament by defeating other "better"
teams, then they deserve to win, because they were the best team for those few
days. Same with chess. I don't think the point of a lot of tournaments is to
determine who is actually better in the long run. That is usually impossible,
unless you have candidate tournaments and matches, followed by a longer match
like the FIDE used to do.
