IMPs is the abbreviation for International Match Points. An IMP tournament is a Mitchell which assigns points used in duplicate bridge in accordance with the IMP table.
An IMP tournament requires a philosophy of play typical of duplicate bridge, real bridge just to be clear!
Even though it is played in pairs, an IMP tournament is ideal for preparing team tournaments.
In a 30 table tournament, it’s as if your pair were playing simultaneously against 29 teams.
In Sweden IMPs have been played for many years with great success. In the USA IMP tournaments are slowly replacing traditional Mitchell tournaments with scores in MP (match points). The IMP is widely used in Internet in the numerous on line tournaments (see BBO for example, where normal matches between pairs with IMP scoring are almost standard).
Some methods have been suggested to apply the same principle to pairs tournaments; one of these is to compare each result with all the others and then convert all differences to IMPs, in accordance with the table published by the WBF.
Normally the sum of all these IMPs is divided by the number of comparisons made, obtaining a score which is more easily understood, and so giving the players an idea of how good, or bad, their score is, because this number indicates how many IMPs were moved in these boards.
The scoring method we propose (across the field, or cross IMP) is the one used in the famous “Cavendish”, the most important invitational international tournament where each pair of players is put up for auction, realizing total prize money of almost $2 million.
