On October 19th 2012, following a proposal by Harris Usdan voted afirmatively by everyone present on October 12th, the Friday Bridge group started to use Chicago scoring instead of Rubber Bridge Scoring. This first experiment was successful and well accepted by the whole group.
There are several versions of this game, also known in the official rules as Four-Deal Bridge. As this name suggests, it is a game for four players which normally is complete in four deals, making it a fun game for social play.
The vulnerability varies from hand to hand in a fixed pattern as follows:
- Hand 1: Dealer North; neither side vulnerable
- Hand 2: Dealer East; North-South vulnerable
- Hand 3: Dealer South; East-West vulnerable
- Hand 4: Dealer West; both sides vulnerable
Each hand is scored duplicate style (2S making 3 is 140, 4H vulnerable is 620, etc.). There is no accumulation of part scores or games from deal to deal.
A multiple of four hands can be played, repeating the sequence of vulnerabilities as often as necessary. For Friday Y’s Men’s Bridge, hands 5 & 6 vulnerability will be:
- Hand 5: Dealer North; neither side vulnerable
- Hand 6: Dealer East; both sides vulnerable
The final score for the six hands is simply the addition of the scores of the six deals played.
