> When it comes to a true rating system, we must never be permitted to pick our opponents. When we meet an opponent again we must alternate colors. So a common record should be maintained by Fide to know which color we must play against a given player. With the electronic age, this should be automated.

> The "Erdős number" should be included in the pairings. If a rated player enters a tournament and has never played the opponent, then the first rating change should be treated as if it was a provisional rating. If two players have played each other before than the ratings should not be considered provisional.
Strange idea. This may work for online server and non-tournament games only. In all other cases current games in current tournament much more important for pairing than old players' statistics against each other.
