B.6.3 Scoring and tie-breaking in team competitions.
B.6.3.1 The sum of scores of each game in a match is referred to as the board points.
The team which scores more board points in a match than its opponents receives two match points, the opponents receives no match points. In the case a match ends in such a way that the sum of the board points is equal to that of its opponents, each team receives one match point. However, if both teams score 0 board points, both teams will receive zero match points.
The ranking will be made according to match points, the team obtaining the highest number of match points being declared the winner of the competition. In case of equality, B.6.3.2 shall be applied for swiss tournaments and B.6.3.3 for round robin tournaments.

The highest number wins. In case of two or more opponents with this same number of match point the lowest results of multiplication should be excluded;
(b) by the number of board points won, the highest number wins;
