     Duplication of boards is recommended whenever hand record printouts

     can be provided.  This continues to be one of the most appreciated

     forms of hospitality a tournament can provide.  Duplication is

     mandatory in all sessions that follow a qualifying round or rounds. It

     is mandatory for all championship events in National, Regional and

     Sectional competition (except KOs and Swiss), unless circumstances

     make duplication a practical impossibility.


     Duplication is mandatory in all matchpoint-scored National Team of

     Four events.


     In events with more than three sections, duplication from ACBL hand

     records is recommended.  Computer-dealt hand records must be

     manufactured by the ACBL or have ACBL approval.  When an event is held

     in two or more separate locations, duplicated hands may be used if

     made from ACBL supplied or approved hand records.


     Floor duplication is considered feasible for up to three sections, but

     is not feasible where different sections of an event are held in

     widely separated locations.  Where four or more sections are entered

     and hand records are not available, it is permissible to duplicate

     pairs of sections rather than the entire field.


     To start sections after having used hand records

     2-board rounds

     13 tables = boards down one e/w up one

     14 tables = boards down one, skip after 7

     15 tables = boards down two

     16 tables = boards down two, skip after 7

     17 tables = boards down two

     18 tables = boards down two, skip after 7


     3-board rounds

     9 tables  = boards down one e/w up one

     10 tables = boards down one, skip after 5

     11 tables = boards down two

     12 tables = boards down two, skip after 5


     4-board rounds

     7 tables  = boards down one, e/w up one

     8 tables  = boards down one, skip after 4

     9 tables  = boards down two


     TDs should take great care that no one has unauthorized access to hand

     records before game time, during duplication or throughout the

     session.  The TD should also enforce restrictions on players wandering

     in their own or other sections during the game.



                                                        PAIRS.033 (PAGE 2) 



     Current ACBL policy prohibits the use of any hands other than those

     generated by an ACBL approved program.  The use of any other hands for

     Sectionals or Regionals is strictly prohibited.


     Any set of hand records used for an event at a tournament (or

     otherwise) may not be reused in any way, shape or form.  This also

     means that any unused hands (i.e., boards 27-36), may not be reused.

                                                          (November, 1990) 


     EFFECTIVE IMMEDIATELY:  Include the set # of the hand records in the

     tournament setup.  (Office Policy - 5/98)



     TDs should check hand records from both sides of the reproduced recaps

     to protect against errors in printing.



     It is the feeling of the ACBL Board that the posting of penultimate

     scores at all computer tournaments is a must for player service and

     satisfaction.  All TDs are instructed to post leader charts at the end

     of the next to last round when scoring is done by computer.  Note that

     when hanging "12th round leaders" in qualifying events TDs should take

     extra care in marking them as not final.



     Whenever a correction is made at a computer tournament following the

     hanging of the original recap sheet, a new recap sheet must be printed

     and hung before the completion of the tournament.

     ORIGINAL PRS BECOME #    14->15      14->15     15->16     16->17

                                             15->16     16->17     17->18


     SKIP AFTER ROUND               7           7          7          8


     # OF TABLES SKIPPED            2           1          2          1

     Ideally, the augmented table will play the added set of boards during

     the first round. Before the 2nd round is called, you must get the new

     table, with the added set of boards, to the proper table in order to

     insure the correct movement of the boards. As the chart indicates, the

     last 1 or 2 tables, both North-South and East-West, will shift back

     one table taking their boards with them and assuming the new pair

     number. Now when the round is called the boards will move normally

     with the additional set in place.


     Using ACBLscore you simply set up a new movement using F9 and select

     #5 which is change movement parameters. One of the questions concerns

     the skip. Answering this properly is all that is necessary in order to

     take care of the additional table.


     Comment: The above is based on having a 13 round movement after adding

     a table to a 13 table game.


     The following will allow you to add a table but play only 12 rounds.

     1. The new pairs become 13 N/S and 12 E/W.

     2. Original N/S 13 moves to N/S 14 and assumes that pair #.

     3. Original E/W 12 becomes E/W 13

     4. Original E/W 13 becomes E/W 14

     5. Skip after six played rounds.



     Should the pairs not get moved properly after the first round and the

     boards remain out of order, the movement will work leaving it as is

     and editing the board movement.


     Set the game up with the new number of tables in play.  Make sure in

     the initial game setup that board 1 is placed where it was played on

     the first round and the E/W pair # is correct.  Then simply go into

     edmove and move the boards the added table actually played on the

     first round to that table # on the grid.  As long as you have told the

     game setup what table and pairs are playing board 1 all other boards

     will be in the order moved initially.  The added set of boards will be

     out of order.  Since the high numbered pairs did not move as intended,

     they retain their original number.



                                                        PAIRS.033 (PAGE 4) 



     The skips occur in the same manner

                                             14->15--double skip after 7

                                             15->16--single skip after 7

                                             16->17--double skip after 7

                                             17->18--single skip after 8


     While this is not the recommended way to add a table, if an accident

     occurs it is fairly easy to recover.



     It is not uncommon to have, at least in small tournaments, sessions of

     from 16-22 tables in which a movement of reasonable technical adequacy

     is required, such as in a Master's Pairs or an Open Pairs Finals. In

     the past the standard procedure has been to use twinned 3/4 movements

     and combined match pointing.


     These movements are universally disliked by players, and are not too

     popular with directors. They do have the purported advantage provided

     by rotating comparisons, but this is the subject of some disagreement.

     In all other respects the suggested movements of this paper are, in my

     opinion, superior.


     In effect, these movements consist of two sub-sections in which the

     boards circulate independently, while the moving pairs progress to the

     other sub-section after playing at the highest numbered table in one.

     In all cases, the traveling pairs move each round to the next higher

     numbered table, boards move next lower within each sub-section. The

     eighteen table game will be described in detail; the others will be

     understood by simply glancing at the master sheet and remembering what

     happened in the 18-table progression.



     Tables 1-9 play one set ("A"), tables 10-18 another ("B"). Stationary

     pairs at 1-9 play the boards in ascending sequence, those at 10-18 in

     descending. Boards 1-2 start at Table 1, 3-4 at 2, etc. up to 17-18 at

     9. The board order is inverted and displaced in the other sub-section:

     25-26 start at Table 18, 1-2 at 17, 3-4 at 16, etc. to 15-16 at 10.

     Note that on round one, Boards 1-16 may be duplicated in the two

     sub-sections, 17-18 and 25-26 may either be duplicated at tables 9 and

     18 respectively, or pre-duplicated (preferred). Boards 19-24 must be

     duplicated by the staff.



     Traveling pairs always move to the next higher numbered table. THERE

     IS NO SKIP. "A" boards move down until they reach Table 1 at which

     point they go to a bye-stand to re-enter at Table 9. "B" boards move

     down until they reach Table 10 at which point they go to the other

     bye-stand to re-enter at Table 18.



                                                        PAIRS.033 (PAGE 5) 



     Assuming that Table 1 is to be seeded, the only suitable* tables are:

                                        16 tables - 1, 5, 9, 13

                                        18 tables - 1, 7, 13

                                        20 tables - 1, 9

                                        22 tables - 1, 12


     *Actually, in some cases other NUMBERS will work, but in 20 and 22

     table progressions only two tables will mutually meet in both




     In Open Pair Finals, there is the restriction that no two pairs shall

     meet who met in the qualifying session. Where there are only two

     qualifying sections, the A qualifiers are simply made N/S, the B's



     For three qualifying sections, a schedule accompanies each master

     sheet for assigning pair numbers. It is assumed that the use of these

     progressions will never occur where there are more than three

     qualifying sections.



     The following is for an odd number of tables using the Web.  This will

     work for 15, 17, 19, 21, 23 or 25 tables.  Boards 1-26 are in play;

     every pair plays every board.


     Subtract 13 from the number of tables.  This will leave an even



     To start the game, pass out the first set of boards in order, two per

     table, to the first 13 tables.  The fragment that remains will get

     boards from two additional set, (at least a partial third set of

     boards will be needed) just as if it were a small even-numbered web.

     For instance, with 19 tables

          Table          Boards

          14            1-2

          15            3-4

          16            5-6

          Bye stand (incoming boards in regular order (7-8 next)

          Bye stand (outgoing boards

          17            3-4

          18            1-2

          19           25-26

          Bye stand (incoming boards in reverse order (23-24 next)


     Boards go into play at table 19 from the byestand, out of play at

     table 17 (the high half of the little "web").  Those 3 tables will

     play their boards in reverse order.  Boards from the other set go into

     play from the buy stand at table 16 (just below the midpoint of the

     little "web"), and out of play at table 1 (boards move regularly from

     table 14 to table 13, since table 14 always the same boards as table

     1.  E/W pairs move to the next higher table each round.
