LAW 78
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.
