What is the Compensation Table? How to use it?

The Compensation Table is a system for playing duplicated bridge with 4 players. The players play in an open room; and the closed room result comes from the Compensation Table. In the closed room, the line with more high card points (hcps) gets points according to how many hcps and how long of a suit they have. If both lines have 20 hcps, the closed room is scored according to the dealer line. If the scoring line has both the major and the minor fit, then the minor fit must be ignored. If the scoring line has more than 33 hcps, then use the 33 hcps result and add +100/+150 (not vulnerable/vulnerable) for every hcp over 33.

How was the Compensation Table created?

The Compensation Table was calculated on the basis of over 60,000 results (over 30,000 boards, because most events were team events). Deals are from world class tournaments, such as the Bermuda Bowl, the Spingold, the European Teams Championship, etc. The table was calculated to be optimal for IMP scoring. Some results above the game level are slightly balanced to avoid situations where you must get more points with weaker hands.

Why is the Compensation Table good?

The Compensation Table provides results from other tables quickly and fairly. It is quick, because almost every bridge player counts their hcps; and in addition, almost every declarer counts their trump suit length. And it is fair, because the Compensation Table takes into account both the distribution and high card strength to report the score from the other table as accurately as possible. There is far less luck factor involved in duplicated bridge with the Compensation Table than in rubber bridge.

The history of the Compensation Table

In Estonia, the Compensation Table is somewhat popular. The older version, which was very similar to this one, was artificially generated from the original compensation method (NYT article). The new version was made in November 2009.
