[1]tderz: I think it is 9 rounds Swiss, not round-robin ( [ext] http://dgob.de/index.htm?lmo/lmo.php ), though I particated only several times as reserve.

Tapir: A nine round swiss tournament in a 10 team league is round-robin. Swiss is only relevant to the bigger 5th league.

Herman: <nitpick> actually 9 round swiss for 10 teams is not exactly the same as round robin, and would give trouble. </nitpick> :-)

Tapir: Can we solve this question and integrate the answer to the text? I don't understand Herman's comment. (With optimal pairing a 2n participant swiss tournament with 2n-1 rounds is round robin as far as i understand.)

Herman: What I was referring to is the fact that with Swiss you pair players with equal scores every round. If you try to do 9 rounds with 10 teams, you may find that in the later rounds, there is no valid pairing for all teams (simple example: after 5 rounds, teams A,B,C,D and E have all already played against teams F,G,H,I and J, but not against each other. So for round six, the group ABCDE must be paired internally, but since it is an odd number of teams, that is impossible). With Round Robin, you make a complete pairing in advance, to guarantee that it will work. So in the leagues with 10 teams, they use round robin, and in the 22 team league they use Swiss.
