TEAM OF FOUR (DUPLICATE BRIDGE) SCORING:
Score on the hand:
Each hand played scores points independently of the other hands played. Points are not carried
forward from previous hands.
Points awarded:
Points are the same as for Rubber Bridge, with the following exceptions:
1. Points for an unfinished rubber are not relevant.
2. A pair succeeding in a contract scores 50 bonus points for a part score, 300 for a non-vulner-
able game, and 500 for a vulnerable game.
3. Points scored by NS in a hand count as a negative score by EW in that hand.
4. The penalty score for a doubled contract with declarer non-vulnerable is 300 for each additional
trick, starting from the fourth trick.
International Match Points:
The score by a team’s NS pair on a hand is added to the score by the team’s EW pair on that hand
(with the result being either positive or negative). The result is then converted to International Match
Points (IMPs), according to the following table. The IMPs for all hands played are then aggregated to
give the result of the match.
