4&5 Pairs

 

            For four and five pairs, the scoring is done manually rather than with an Excel scoring program.  For each configuration, there are three sheets used:  “Table 1”, “Table 2”, and “Scoresheet”.  The first two sheets are kept at their respective table, and the scoresheet is usually kept at Table 1, where the Director preferably starts out playing N-S.  The following explains how each of these sheets is used.

 

            The “Table 2” sheet is simplest.  For either four or five pairs, the two listed pairs play a single round.  For each board, the contract and the result are recorded, and the raw score is written in terms of N-S points.  Thus if N-S bid and make 4S nonvulnerable, the score will be 420 points, but if E-W do that, the score recorded will be -420 points.

 

            The “Table 1” sheet is more complicated.  For four pairs, the two listed pairs simply play a single round, but for five pairs there are two subrounds, with the Director’s opponents changing:  about halfway through the round, the sitout pair comes in and the Director’s pair changes direction.  (This is why it good to have the Director at Table 1.)  This special movement for five pairs breaks up the sitout for each pair into two nonconsecutive subrounds, except that the Director’s pair sits out during the whole final round.  Again the score for each board is recorded in terms of N-S points.  The boards are shared during each round, and for five pairs it is imperative that Table 1 play the lower-number boards first, after which the sitout pair will come in for the higher-number boards.

 

            After each round, the N-S points from Table 2 are transcribed to the “Table 2” column on the “Table 1” sheet, and then subtracted from the Table 1 N-S points for that board to give the entry in the Difference (“Diff.) column.  This is done according to the standard arithmetic rules for adding and subtracting positive and negative numbers.  For example, if on a particular board the N-S points at Table 1 are -420 and those at Table 2 are -450, the resulting difference is +30.  These differences are then converted to imps using a standard Imp table (such as given on the “Scoring for Home Duplicate Bridge” page of this website).  The imps for each round or subround are then added up and written down on the far right side of the “Table 1” sheet (just right of the table itself).

 

            Now the “Scoresheet” sheet is used, with entries for each full round (four players) or for each subround (five players).  If Imp scoring is used, the total imps for that round or subround are entered on the left side according to whether the imps are positive or negative, under the pair numbers.  (For five pairs, the sitout pair gets the average imp score for that subround, rounded down.)  These imp scores are then transferred to the right side, and a running total is kept throughout the session.  If Victory Points are used, the same procedure is followed, except that the imp total for the round or subround is first converted to victory points according to the table at the bottom of the scoresheet, and the pairs without the imps also receive victory points unless they did really badly.  For example, suppose that four pairs are playing a total of 24 boards, and in the first round the total imp score was -3 imps (the sum of the imps for Boards 1-4 given on the far right of the “Table 1” sheet); if Imp scoring is used, Pairs 1 and 2 will each receive 3 imps and Pairs 3 and 4 will get nothing, while if victory-point scoring is used, Pairs 1 and 2 will each receive 10 VP’s and Pairs 3 and 4 will each get 4 VP’s.

 

            All these sheets for four or five pairs are given in the 4&5 Pairs subfolder of the Word folder (itself a subfolder of the HDB folder).  All the HDB files start with “Br” (for “bridge”), and the fifth through eighth characters specify the number of pairs and the number of boards played.  The third and fourth characters specify the nature of the file:  “Sc” for “Scoresheet”, “T1” for “Table 1” sheet, and “T2” for “Table 2” sheet, for the present 4&5 Pairs subfolder.  Thus the file “BrT20520.doc” is for the “Table 2” sheet for five pairs playing 20 boards.

 

            As shown in the table at the bottom of the Introduction webpage, victory-point scoring is available for all of the four-pair configurations and for five pairs playing 30 boards.  If Imp scoring is desired, you should use “BrSc04.doc” or “BrSc05.doc” for four or five pairs, respectively.  (It doesn’t matter how many boards are being played, for these scoresheets.)  However, for victory-point scoring you should use the scoresheet which specifies the number of boards, such as “BrSc0430.doc”; these have the appropriate Victory Point table at the bottom.
