LAW 78 - METHODS OF SCORING AND CONDITIONS OF CONTEST

A. Matchpoint Scoring

In matchpoint scoring each contestant is awarded, for scores made by different contestants who have played the same board and whose scores are compared with his, two scoring units (matchpoints or half matchpoints) for each score inferior to his, one scoring unit for each score equal to his, and zero scoring units for each score superior to his.

B. International Matchpoint Scoring

In international matchpoint scoring, on each board the total point difference between the two scores compared is converted into IMPs according to the following scale.

The Conditions must not conflict with law or regulation and shall incorporate any information specified by the Regulating Authority. They should be available to contestants.
