Add article description

International match points (IMP) within the card game of contract bridge is a measurement for conversion of the absolute contract bridge scores. The total point difference between two scores is compared to a scale ranging from 1 to 24.[1][2]

More information Point difference, IMPs ...

IMP score is used in competition bridge, including duplicate bridge (including at some online bridge websites),[4] but rarely within any kind of companion bridge, and never if playing rubber bridge.[5]

Tactics at IMPs differ from those of matchpoints and are similar to those of rubber bridge. The declarer's primary objective is to make the contract without jeopardizing it in a quest for overtricks; for the defense it is to defeat the contract without worrying about surrendering overtricks.[6]
