TOURNAMENT PAIRING METHODS
The following are brief summaries of the tournament
pairing systems commonly used singly or in combination in SA
- Round Robin: every player in the group plays
every other player once. Repeated round robins are
playable. The number of rounds played in a full round
robin is the number of players less one.
- King-of-the-Hill (KOTH): players in the field are
ranked in order of games won with (usually) cumulative
margin as a secondary ranking. The player currently in
1st position plays the player currently in
2nd position, the player currently in
3rd position plays the player currently in
4th position and so on.
- No repeat KOTH or "Australian Draw": Going down
the current standings the computer program will pair an
unpaired player against the next highest player he has
not previously played.
- "Swiss" Pairing: This is normally used for the
first round before standings have been determined.
Players are seeded in order of ratings. In a field of N
players the 1st-seeded player plays Player
(N/2)+1; the 2nd-seeded player plays Player
(N/2)+2 and so on.
- Progressive Round Robin: the field is seeded by
ratings and then divided into equal sized groups which
play a round robin within each group. Those finishing at
the bottom of their group are demoted to the next lower
group for the next round and those finishing at the top
of their group are promoted.
