International Match Points International Match Point scoring was first introduced at the 1938 European Championships in Oslo. Its purpose is to moderate the disproportionate effect that a very large score differential (or "swing') on just one or two boards could have on the outcome of a contest involving dozens of boards. The difference in total points scored by each team is converted to International Match Points (IMPs) using a standard table which has sublinear dependencies on differences to reduce the effect of such large swings. Originally named European Match Points (EMPs), the scale provided for a maximum gain of 12 points as shown in the table below. A revised table was adopted for the 1948 European Championships in Copenhagen with a maximum of 15 points. North American players were first introduced to this scoring method at the 1951 Bermuda Bowl match in Naples, Italy. Further revisions were made in 1961 and again in 1962 by the World Bridge Federation.
