Matchpoint (MP Scoring)
Take all the N/S scores and give
the best N/S score 100% and the worst N/S score 0% and then you calculate the % scores for the rest of the field. In MP's one extra trick can make the difference between getting a top or an average with the rest of the field.
Also your choice of contract can be significant. Better to be in 2 NT making 2, than 2H making 2, but if 2H making 3, then that is even better.
