The following criteria are taken into account for pairing:a) Provisional team score for the date of pairing. Recalculation for the closed accounts is applied. If the score difference is 2 points and less, and the match is not won mathematically (>50% points), it is considered drawn. b) Provisional Buchholz coefficient (sum of team scores of all opponent teams)c) Power (nb of players + average rating)
The procedure of pairing is transparent. The provisional team scores and additional criteria (if needed) are published together with the schedule
2. In general, teams are paired to others with the same team score.
3. Pairing for the first round The Team's list is arranged by Power and divided into two equal parts: The teams from the upper part of the list are placed on the left and those from the lower part, on the right.
The first player from the left-hand list plays the first player from the right-hand list, the second plays the second, etc.
4. Pairing procedure for the remaining rounds.
Teams are divided into groups based on their provisional team score from highest to lowest. Each group including an even number of teams.
Within the score group teams are arranged by Buchholtz and Power and their pairing proceeds as above (#3).
5. If the number of teams of the score group is odd, a team from the next possible lower score group shall be transferred to the score group to be paired, who has not yet played with at least one of the players of the higher score group.
If there is a choice, then the team with the highest Power is to be transferred.
6. Any two participating teams scheduled to play in WCL playoffs or CWC Participation round can be forced-paired to play each other in WCOS to avoid excess match load if:
a) Their match by CWC/WCL schedule is set close to WSOS schedule;
b) There is no more than 1 point difference between their current standings;
c) Admins of both teams do not object to such suggestion.
The player eligibility issues in these matches will be ruled by the provisions of WCL or CWC correspondingly.The recalculations and final results for the purposes of WCOS will be defined by the rules of WCOS.

If the teams equal to the number of points the supplementary criteria are applied to determine standings:
a) Buchholtz coefficient and if it is equal, then
b) Summary percentage of points taken in all matches
All matches, which are not finished at the new season day, are declared won if a team:
a) has scored more than 50% possible points in the match (won mathematically), and if not, then:
b) all unfinished games in that match are adjudged by the TD using top computer engines and common sense and considered won if there is a clear advantage and drawn otherwise.
G. Fairplay
If a player account is closed, all of his matches will be declared lost.
Each player can play only for one team in the league during the same season. If he plays for several teams by mistake, he can declare, which team is his "home team". By default, the team whose team match with his participation was opened earler is considered "home team". All wins and draws scored by him for other teams are deducted from match scores.
In any league match it is not allowed to have more than 1 foreign flag (mercenary) in the first 10 tables and 2 mercenaries for every following 10 tables in the match. If such case occurs in a match, all wins and draws of extra mercenaries will be subtracted from match score.
The following flags are not considered mutually foreign: all flags on the British Isles; all flags of the former Yugoslavian republics and Albania; all flags of Spain and its provinces; Swedish and Danish; Azeri and Iranian; Canadian and Martinicain; Russian and Ukrainian (for team Sevastopol only); Greek and Cyprus - the list can be expanded whenever it is well-founded and concerns many players.
It is presumed that a player flag is constant during the season. No manipulations with flags and locations to bypass the rules are allowed. All players involved in such manipulations will be treated as mercenaries if their manipulations are reported.
Under no circumstaces shall admins discourage low rated players to join their Team or remove any players, especially low rated, from their roster - unless they are mercenaries, multiteamers, or have above 25% of timeouts.
The team admins shall inform their teammates about the rules content, especially in what concerns the fairplay rules.
