There are some differences between how Teams matches are scored versus normal Matchpoint Pairs. Knowledge of these differences can affect your tactics.
In a normal matchpointed pairs event, you receive 2 matchpoints for each pair that you beat on any given board. (We use Double Matchpointing. With Single Matchpointing you would get 1, not 2.) There may be slight adjustments to these scores (“factoring”) to compensate for pairs who play less boards (e.g. some pairs sit out, some don't), or for boards which are played less often (e. g. they were “played” at a sit out table, while some others weren't). Your score for the session is your total for all the boards you played.
In a teams match, the other scores on the board (those of the other teams) has no effect. Only your team's scores are relevant. There will be one score where your NS pair played the board against their EW pair, and one where your EW pair played against their NS. Your team score is the sum of your NS score and your EW score, bearing in mind that either or both scores could be negative. That sum is then converted to International Match Points (IMPs) according to a standard scale. IMPs scores are positive or negative (unlike matchpoints, which range from zero to a “top”).
Your total IMPs against a particular team determines the result of that match.
Your score in the event as a whole (assuming there are more than 2 teams), is arrived at by another conversion. The IMPs difference in each match is converted to Victory Points (VPs). Your overall placing in the event will (usually) be determined by the total of your VPs from all matches.
In a Pairs event, how well you do on a board depends on how many pairs you beat; not how much you beat them by. For example, if you play in 3NT making 10 tracks, for +430, and all the other pairs played in 4 Hearts making 10, for +420, you would get a “top” - the maximum score on that board. This is so even though you only beat the other pairs by a paltry 10 points.
By the same token, if you bid and made 6 Hearts Vul, for +1430, when every other pair was one off in 6H, for -100, you have beaten all the other pairs by 1530 points. But you only get the same “top” score as you got for outscoring them by 10.
But in teams scoring it is the size of your win or loss which is important. In the first example, if you bid 3NT making 10, for +430, and at the other table the opposing team bids and makes 4H, giving you -420, your aggregate score is +10. Plus 10 converts to 0 (zero) IMPs. The extra 10 points gains you absolutely nothing. But looking at the Slam example, your +1430 added to your team mates +100 gives your an aggregate of +1530, which converts to 17 IMPs. This is a great score! The IMPs scale tops out at 24 IMPs for an aggregate of 4000 or higher. 17 out of a possible 24 is a great score. Most boards will probably result in a score of only 2 or 3 IMPs. A game swing is about 10 or 12 IMPs, depending on vulnerability.
For those who follow Le Tour de France, or multi-stage bicycle races in general, there is a good analogy to Bridge. In the TDF Green Jersey competition, it doesn't matter what your time is, only where you place. By contract, in the Yellow Jersey competition, it is the time difference to your rivals which is important. Your placing on any stage is immaterial. The Green Jersey is Matchpoints. The Yellow Jersey is IMPs.
The most important tactical application of different scoring is with regard to overtricks. At matchpoints, an overtrick might be crucial; the difference between a bottom and a top. You may even decide that it is worth risking your contract for an extra overtrick. After all, a bottom by 30 scores the same as a bottom by 1400. However, at IMPs you should never take any risks for the sake of making an overtrick. Even an “almost certain” overtrick is not worth risking your contract for. The overtrick is worth 0 or 1 IMP, 2 at most. But failing to make your contract will cost at least 4 IMPS (for a low part score) and up to, say, 19 IMPs for going 1 off in a vulnerable Grand Slam.
VPs are usually allocated at combined total of 30 VPs per match. For a drawn match, each team gets 15 VPs. For a small win, you might get 16 VPs and your opponents 14. Or 17 to you, 13 to your opponents, and so on. But there is an upper limit of 25. You can never win 30 VPs to 0, or 29 to 1. Those scores would be 25-0 and 25-1 respectively.
You will usually find an IMPs conversion table on any Teams score sheet. But you won't always see a VP scale there. This is because the VP scale varies depending on the number of boards in a match, and without knowing in advance what the length of the matches will be, it is impossible to predict the correct VP scale.
