Extended Direct Encounter for Teams

Extended Direct Encounter for Teams, abbreviated EDE, adapts direct encounter to competitions with two scoring systems. Match Points, or MP, reward the overall result of a match between two teams. Game Points, or GP, add the individual results scored on the boards.

The competition defines which score is primary. EDE first applies direct encounter among the tied teams using that score. If the procedure breaks no tie, it is repeated with the secondary score. The basic idea is to examine what the tied teams achieved against one another before moving to criteria based on their results against the rest of the event.

Whenever the calculation separates a subset but leaves several teams tied, the procedure restarts inside the new group. Restarting prevents results against teams that have already left the relevant tie from continuing to affect that subgroup.

If exactly two teams remain tied in both MP and GP, the competition regulations must state whether team-knockout tie-breaks follow and in what order. The regulated options include Board Count, a total weighted by board number, Top Board Results, and Bottom Board Elimination. EDE therefore does not define the entire final sequence by itself.
