6.3 Improvements
If the players have already played each other, then the "white" player is paired with the first "black"
player whom he has not played before, from the lower rows;
If such a coincidence takes place in the last row for a group of players with the same score, then the
last but one row is changed.
If a coincidence takes place in a row No. k of a group with the same score and all the "blacks" from
the lower group have already played with the "white" No. k, then we change the pairing in row No.
k - 1, if this does not work, in row No.k-2, etc.
If the "white" No. k has already played with all the "blacks", we look for an opponent for him,
beginning with the "white" No.k+1 down to the end of the column, and then, beginning with the
"white" No. k -1 down to the "white" No.1. The colors of the pairings are assigned due to the color
allocation rules.
6.4 Floater
The aim of the pairing procedure is to pair all players within a score group.
If that cannot be achieved the remaining unpaired players are transferred to the next lower score
group and treated according to chapter 8.
If there is a choice the floaters should be chosen due to these characteristics with decreasing
preference:
- the player was not floater from higher score groups and can be paired in the lower score group;
- the player was not floater from higher score groups and cannot be paired in the lower score group;
- the player was floater from higher score groups and can be paired in the lower score group;
- the player was floater from higher score groups and cannot be paired in the lower score group.
7. Transfer of players to meet the requirement of Chapter 6.
If the requirement of the standard pairing procedure is not fully fulfilled the following transfers
shall be carried out in the order listed below
7.1 If a player has already played with all the players of his own score group, a player from the next
possible lower score group is transferred to the score group to be paired who has not yet played with
the player in question and can be paired according to the color allocation rules.
The player to be transferred should fulfill the following requirements with descending priority:
- the due color is opposite to the due color of the player in question;
- if there is a choice, then the player with the highest R is to be transferred;
- if there are more than one players having the same R then the one with the lowest ARO will be
transferred.
7.2 If the number of players of the score group odd, a player 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 and is allowed to be paired according to the color allocation
rules.
This player to be transferred should fulfill the following requirements with descending priority:
- his due color is opposite to the dominating due color of the higher score group;
- if there is a choice, then the player with the highest R is to be transferred;
- if there are more than one players having the same R then the one with the lowest ARO will be
transferred.
7.3 If the number of players in the score group is even and the number of Whites exceeds the Blacks
by 2n, then n "white" players, who have the lowest ARO, are transferred to the black group. If their
