METHODS
OF SCORING
- 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:
Difference Difference Difference in points IMPs in points IMPs in points IMPs 20 - 40 1 370 - 420 9 1500 - 1740 17 50 - 80 2 430 - 490 10 1750 - 1990 18 90 - 120 3 500 - 590 11 2000 - 2240 19 130 - 160 4 600 - 740 12 2250 - 2490 20 170 - 210 5 750 - 890 13 2500 - 2990 21 220 - 260 6 900 - 1090 14 3000 - 3490 22 270 - 310 7 1100 - 1290 15 3500 - 3990 23 320 - 360 8 1300 - 1490 16 4000 & upwards 24 - C. Total Point Scoring
- In total point scoring, the net total point score of all boards played is the score for each contestant.
- D. Special Scoring Methods
- Special scoring methods are permissible, if approved by the sponsoring organization. In advance of any contest the sponsoring organization should publish conditions of contest detailing conditions of entry, methods of scoring, determination of winners, breaking of ties, and the like.
LAW 79
TRICKS
WON
- A. Agreement on Tricks Won
- The number of tricks won shall be agreed upon before all four hands have been returned to the board.
- B. Disagreement on Tricks Won
- If a subsequent disagreement arises, the Director must be called. No increase in score need be granted unless the Director is called before the round ends as specified in Law 8 (but Law 69 or Law 71 may supersede this provision when there has been an acquiescence or a concession).
- C. Error in Score
- An error in computing or tabulating the agreed-upon score, whether made by
a player or scorer, may be corrected until the expiration of the period
specified by the sponsoring organization. Unless the sponsoring organization
specifies a later
time, this correction period expires 30 minutes after the
official score has been made available for inspection.
An earlier time may be specified when required
by the special nature of a contest.
