Rules for organizing, conducting, and participating in online Heroes of Might and Magic III tournaments.

I wonder if any other sports use a rating system in a similar way? I can't recall any examples. Perhaps weightlifting, but there it's the opposite – the lighter person wins.

In Russian billiards, for example, in amateur tournaments, players with a high rating (from KMS level) often give a handicap to the others. Which is, naturally, also "the opposite."

Of course, even a blind draw is preferable to selecting players based on rating.
