|Table Guide Cards
for Rotary Movements
A movement that is "rotary" in nature — that is, a
design such that the moving pairs follow each other around the room in an
uninterrupted pattern — lends itself to the use of table guide
cards, which eliminate the necessity of providing said instructions in another
way. The so-called Howell movements and some Individual and
Team arrangements fall into this category.
Several vendors sell guide cards for the Howells and Individuals adopted long ago as "standard" by the ACBL (and subsequently by other organizations as a matter of convenience). Because I am not trying to supplant the printing industry, most such schedules are not featured here. What you will find are some original creations that provide one or more of the following benefits:
The downloadable file contains the data for all the movements; simply
discard the ones you don't wish to use. The PDF files enable easy
printing of guide cards and master sheets on standard
paper. The other files are compatible with the ACBL Score program.
Just copy the .MOV files into your \ACBLSCOR\MOV folder and the
.IND files into the \ACBLSCOR\IND folder. When you later
specify an Alternative Movement during a game setup, they will show up on
the list, easily identifiable by the hyphens in their names.
The filenames reflect the number of tables (pairs) or players (individuals) and the number of rounds. No more information can be included, because ABCLscore has a limitation on the length of a filename. When selecting a movement during a game setup, however, more details are available on the computer screen.

|H-04-06-24||Shorter session • Two stationary pairs|
|H-05-08-24||Shorter session • Two stationary pairs|
|H-05-07-28||Three stationary pairs instead of one|
|H-07-09-27||Easy conversion from 6-table game • Eliminates a 4-board sit-out|
|H-06-09-27||Far better balance|
|H-04-07-28||Better table arrangement and bye-stand positioning|
|H-06-11-22||Two bye-stands instead of four|
These movements have long been out of favor; but they can come in handy for home games or those times when most of your club's clientele is trapped in a snowstorm.

ABOUT MOVEMENT CONFIGURATION
Ideally, a rotary movement is set up such that the the tables are bunched
together as closely as possible with respect to the board sets, and the boards
go out of play from
Table-1 to a bye-stand. That is the
natural order of things. Not all movements can be so well-organized,
however. The 4-table Howell requires a pair of bye-stands,
and certain others need even more.
The well-known Howell and Individual schedules have been around since the
early days of duplicate; unfortunately, those same original designs are being
used to this day even though better setups are available in many cases.
For example, the ACBL adopted a
4-table configuration that starts with
board sets 1-4-6-7, even though a less confusing and more
intuitive 1-2-3-5 matrix was known at the time.
Similarly, the standard 6-table complete Howell utilizes no fewer than four
bye-stands, even though only two are needed. It didn't have to be
that way, because creating rotary movements simply isn't that difficult.
Admittedly, a computer is very helpful in this regard.
ABOUT MOVEMENT BALANCE
Most directors who opt for a Howell movement expect it to provide a more
equitable game, in that the pairs compete against each other for the matchpoints
to some extent; unfortunately, that is not always the case. Ideally, every
pair would play, as nearly as possible, half the boards in the same direction as
every other pair and half the boards in the opposite direction. Of all
movements analyzed, only four were found to be capable of perfect
balance — the complete Howells for 4 tables and 6 tables,
plus the complete Individuals for 8 players and 12 players.
The other complete Howells are reasonably and symmetrically balanced.
so-called three-quarter movements, though —
curtailed such that not all pairs meet — are mathematically flawed;
and the arrow-switching scheme for the stationary pairs further corrupts
the purity of the matrix. Under these conditions, programming even a
palatable configuration is problematical. In particular, the standard
Howell for 6 tables, 9 rounds is so utterly unfair to certain
pairs that it should have been replaced seventy years ago.
The ACBL Score program has a built-in feature for designing virtually any
movement of one's desire. For those that I tested, however, player
balances ranged from mediocre to horrid; in fact, a couple of them are worse
than the dreaded
6-table Howell. The program will generate a
mathematically workable schedule all right; but no coding has been spared to
select a matrix that is even remotely equitable. Additionally, the usage
of any of those movements would entail the printing of personal guide cards.
Now you don't have to do that, however, because new and improved table guide cards are available right here at Ted's World. For every schedule posted, all possible configurations have been tested and the fairest available option has been selected. Enjoy.
The posting of other movements would be considered upon request.
