A Bridge Too Far (Posted on 2013-06-19) Difficulty: 3 of 5
In the game of duplicate bridge, the idea is to get a better score than the other pairs who, during the course of the session, play the same hands at different tables. A pair will get one point for every score they beat, and half a point for every score they tie.

One particular hand was played eight times. All pairs playing North-South scored either +420 or +450. (The derivation of these scores doesn’t matter, although they are common and result from a contract of, say four hearts.)

One of the pairs that scored +420 noted that this score was worth 2.5 points at the end of the session.

How many points would this pair have received had they scored +450 instead?

Some Thoughts Worldwide scoring Comment 2 of 2 |
Incidentally, a week and a half ago I played in a worldwide event where 8,360 pairs in 35 countries played a common set of hands.  We were matchpointed across the whole world.

On hand # 11, for instance, the hand was played by 2,086 north-south pairs.  432 of them scored +450 and 31 scored +420.  461 did even better and 1162 did even worse.  So, scoring +450 instead of +420 was worth an extra (432 + 31 - 1)*.5 = 231 matchpoints (before factoring to compensate for the fact that not every hand was played by the same number of pairs).

I wound up with 89,995 factored match points, which was good for 402nd in the world (top 5% out of 8,360).  It was very cool.  Not bragging, just reporting.
