IMPs and Matchpoints

        There are two main ways to score a duplicate bridge event: IMPs and Matchpoints. The differences between these two scoring systems often lead to different styles of play.

 

         Matchpoints.     When playing matchpoints, your score is compared to the other teams that played the same hands, and you receive points as follows:

Matchpoints
    You are awarded 1 matchpoint for every pair that you beat on a given board, and
    You are awarded matchpoint for every pair that you tie on a given board.

For example:

Rank Matchpoints
Top (1st place) 2
Tied for 1st 1
Middle (2nd) 1
Wash (3-way tie) 1
Tied for 2nd
Bottom (3rd place) 0
Matchpoints with 3 pairs.

When playing matchpoints, all hands count equally, so that you are not penalized too much for one horrible play or given too many points for one moment of brilliance. Keep the following in mind:

 

         IMPs.     IMPs is the normal method of scoring in team events, or any event where only two tables play each board. When playing IMPs, your score on a contract is compared to the score of the other team who played the same hands. You are then either rewarded or penalized a certain number of IMPs based on the difference:
