Pairing Methods Used

(When and How Accelerated Pairings Will Be Used)

Goals:

  1. clear 1st-place winner
  2. good competition (better players play better players earlier)
  3. fair opportunity for prizes (lower players can't easily "sneak in")
Using accelerated pairings with the break below the regular cut effectively balances the goals
More rounds in a section helps to "recover" from an initial imbalance
Draws or half-byes in the first round above the break will cause the break to be lowered so the best players don't meet too soon.
Reversing colors in round 1 for some boards makes the colors match for natural pairings in rounds 2 & 3 with 8 or 16 in score group.
Teammate and club-mate pairings will be avoided with a score group.
